  Introduction Logging serves as a cornerstone in the development and deployment life-cycle of any application. Serilog, a renowned logging library for .NET, offers robust features for logging messages to various destinations, including text files. However, deploying applications to IIS servers can introduce challenges, particularly pertaining to permissions issues that impact logging functionality. In this blog post, we'll delve into troubleshooting steps and solutions for addressing Serilog logging challenges in a .NET Core 7 application deployed to an IIS server.   Identifying the Issue Upon deploying a .NET Core 7 application utilizing Serilog for logging to an IIS server, you might encounter instances where log messages fail to be written to the designated text file. Upon investigation, it becomes apparent that the application lacks the requisite write permissions for the directory where log files are intended to be stored. This obstacle impedes logging functionality and necessitates corrective measures.   Troubleshooting Steps Review Logging Configuration: Commence by scrutinizing the Serilog logging configuration within your .NET Core 7 application. Ensure that the Serilog configuration accurately specifies the file path and logging sink for storing log messages. This step verifies that the logging setup aligns with the requirements of your deployment environment. Inspect File System Permissions: File system permissions are pivotal in enabling applications to write log files. Navigate to the directory designated in your Serilog configuration and examine its permissions settings. Confirm that the IIS application pool identity or the user account running the application possesses adequate permissions to write to the target directory. Grant Write Permissions: In cases where the directory lacks essential write permissions, take action to grant appropriate access rights. Depending on your deployment environment and security policies, you may need to manually adjust permissions or enlist the support of system administrators to ensure proper authorization for the application. Implement Log File Rotation: When log files accumulate rapidly, implementing log file rotation mechanisms can prevent log files from becoming excessively large. Configure Serilog to rotate log files based on size, date, or other criteria to maintain manageable log file sizes and simplify log file management. Validate Logging Functionality: Following the resolution of permissions issues and adjustments to logging configurations, conduct comprehensive testing to verify that log messages are being successfully written to the designated log files. Perform test scenarios that encompass various aspects of your application to ascertain logging functionality under diverse conditions.   Conclusion Effective logging is indispensable for diagnosing issues, monitoring application health, and troubleshooting errors in .NET Core 7 applications deployed to IIS servers. By adhering to the troubleshooting steps outlined in this blog post, you can address Serilog logging challenges stemming from permissions constraints and ensure seamless logging functionality in your deployed applications.

To utilize custom fonts from your Dotnet codebase in HTML or PDF documents, follow these steps: Add the fonts you intend to use for your PDF or HTML documents. Ensure they are in the .ttf extension format. <PackageReference Include="Polybioz.HtmlRenderer.PdfSharp.Core" Version="1.0.0">   Include the necessary package by adding the following line to your project file: Initialize the IServiceCollection to utilize the CustomFontResolver class. You can achieve this by adding the following extension method:   public static class IServicesCollectionExtension { public static IServiceCollection InitializeDocumentProcessor(this IServiceCollection services) { GlobalFontSettings.FontResolver = new CustomFontResolver(); return services; } } Initialize the class in your program file:   builder.Services.InitializeDocumentProcessor();   Specify the DefaultFontName you wish to use. You can also manage bold and italic styles. public class CustomFontResolver : IFontResolver { string IFontResolver.DefaultFontName => "Rubik"; public FontResolverInfo ResolveTypeface(string familyName, bool isBold, bool isItalic) { if (isBold) { if (isItalic) { return new FontResolverInfo("Rubik#bi"); } return new FontResolverInfo("Rubik#b"); } if (isItalic) return new FontResolverInfo("Rubik#i"); return new FontResolverInfo("Rubik"); } public byte[] GetFont(string faceName) { switch (faceName) { case "Rubik": return CustomFontHelper.Rubik; case "Rubik#b": return CustomFontHelper.RubikBold; case "Rubik#bi": return CustomFontHelper.RubikBoldItalic; case "Rubik#i": return CustomFontHelper.RubikItalic; } return GetFont(faceName); } }   Define a helper class CustomFontHelper to facilitate loading font data. Ensure you have added the fonts for all the types you intend to use. public static class CustomFontHelper { public static byte[] Rubik { get { return LoadFontData("Rubik-Light.ttf"); } } public static byte[] RubikBold { get { return LoadFontData("Rubik-SemiBold.ttf"); } } public static byte[] RubikBoldItalic { get { return LoadFontData("Rubik-SemiBoldItalic.ttf"); } } public static byte[] RubikItalic { get { return LoadFontData("Rubik-Italic.ttf"); } } static byte[] LoadFontData(string name) { using (Stream stream = File.OpenRead("Fonts/" + name)) { if (stream == null) throw new ArgumentException("No resource with name " + name); int count = (int)stream.Length; byte[] data = new byte[count]; stream.Read(data, 0, count); return data; } } } By following these steps, you can seamlessly integrate custom fonts into your HTML and PDF documents from your Dotnet codebase, without needing to specify the font-family in the HTML directly. You can also pass font styles directly through code.

What is MinimalAPI?  Minimal APIs are a simplified way of building web APIs in ASP.NET Core. They are designed for scenarios where you need a quick and minimalistic approach to expose endpoints without the overhead of a full-fledged MVC application.    Why Minimal APIs?  Efficiency: Write less, do more. A mantra for the modern developer.  Performance: They’re lean, mean, and fast, perfect for high-performance scenarios.  Ease of Use: New to .NET? No problem! Minimal APIs are accessible and easy to grasp.  Flexibility: Simplicity doesn’t mean limited. From microservices to large-scale applications, they’ve got you covered.    How Minimal APIs Work?  Minimal APIs leverage the WebApplication class to define routes and handle HTTP requests. They rely on a functional approach, allowing developers to define endpoints using lambda expressions.    Limitations of Minimal API  No support for filters: For example, no support for IAsyncAuthorizationFilter, IAsyncActionFilter, IAsyncExceptionFilter, IAsyncResultFilter, and IAsyncResourceFilter.  No support for model binding, i.e. IModelBinderProvider, IModelBinder. Support can be added with a custom binding shim.  No support for binding from forms. This includes binding IFormFile. We plan to add support for IFormFile in the future.  No built-in support for validation, i.e. IModelValidator  No support for application parts or the application model. There's no way to apply or build your own conventions.  No built-in view rendering support. We recommend using Razor Pages for rendering views.  No support for JsonPatch  No support for OData    How to create a Minimal API?  Creating a Minimal API closely mirrors the traditional approach, so you should encounter no significant challenges. It is a straightforward procedure that can be accomplished in just a few easy steps.  Let's get started:  Step 1:   Open Visual Studio and select the ASP.NET Core Web API.  Provide a preferred name for your project and select the location where you wish to store it.  For the final step, choose the targeted framework, ensure that the "Configure for HTTPS" and "Enable OpenAPI support" checkboxes are checked, and, most importantly, leave the checkbox "Use controllers (uncheck to use Minimal API)" unchecked. Then, click the "Create" button.  Step 2:  Create one class with two fields and create one list class with some static values.  namespace MinimalAPI { public class Student { public int Id { get; init; } public string Name { get; set; } } public static class StudentList { public static List<Student> student = new List<Student>() { new Student() { Id = 1, Name = "Test1", }, new Student() { Id = 2, Name = "Test2", }, new Student() { Id = 3, Name = "Test3", } }; } } Now add register new endpoint in Program.cs file.  app.MapGet("GetAllStudent", () => StudentList.student); Run the project and see the output.  I have added Create, Update and Delete student endpoint. See the full code below.  using MinimalAPI; var builder = WebApplication.CreateBuilder(args); // Add services to the container. builder.Services.AddControllers(); // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle builder.Services.AddEndpointsApiExplorer(); builder.Services.AddSwaggerGen(); var app = builder.Build(); // GetAll app.MapGet("GetAllStudent", () => StudentList.student); // GetById app.MapGet("GetByStudentId/{id}", (int id) => StudentList.student.FirstOrDefault(user => user.Id == id)); // Create app.MapPost("CreateStudent", (Student student) => StudentList.student.Add(student)); // Update app.MapPut("UpdateStudent/{id}", (int id, Student student) => { Student currentStudent = StudentList.student.FirstOrDefault(user => user.Id == id); currentStudent.Name = student.Name; }); // Delete app.MapDelete("DeleteStudent/{id}", (int id) => { var student = StudentList.student.FirstOrDefault(user => user.Id == id); StudentList.student.Remove(student!); }); // Configure the HTTP request pipeline. if (app.Environment.IsDevelopment()) { app.UseSwagger(); app.UseSwaggerUI(); } app.UseHttpsRedirection(); app.UseAuthorization(); app.MapControllers(); app.Run(); Run the code and see the output. Conclusion:  Minimal APIs in ASP.NET Core, introduced in .NET 6, offer a simplified and concise approach to building lightweight HTTP services, reducing boilerplate and emphasizing convention-based routing. While ideal for rapid development of small to medium-sized APIs, they lack advanced features found in traditional ASP.NET Core applications and may not be suitable for complex scenarios.

Understanding Import and DirectQuery Modes in Power BI Power BI empowers users to analyze data from various sources. This post dives into two key connection modes: Import and DirectQuery. Each offers distinct advantages depending on your data analysis needs.   Import Mode: Power and Flexibility Import mode brings your data directly into Power BI's internal memory. This creates a copy of the data, allowing for: Faster Performance: Since the information is readily available, visualizations and calculations happen swiftly. Enhanced Data Manipulation: Transform and mold the data to your liking before loading, offering greater control compared to DirectQuery. Offline Accessibility: Reports built with import mode function flawlessly even without an internet connection. However, there are limitations to consider: Resource Demands: Importing large datasets strains system resources like RAM and disk space. Data Refresh: Changes made to the source data won't be reflected until you refresh the import. Setting up automatic refreshes can help, but large datasets can lead to slow refresh times.   DirectQuery Mode: Real-Time Insights DirectQuery mode bypasses internal storage. Instead, it sends queries directly to the original data source. This approach offers several benefits: Real-Time Analysis: Always see the latest data without manual refreshes. Changes in the source database are instantly reflected in your reports. Large Dataset Efficiency: DirectQuery handles massive datasets effectively, avoiding memory constraints encountered in Import mode. Guaranteed Accuracy: Reports always showcase the most up-to-date information. However, DirectQuery comes with its own limitations: Limited Functionality: Certain features like calculated columns and complex data models are restricted due to the reliance on live data. Potential Performance Lag: Queries travel back and forth between Power BI and the source system, impacting response times compared to Import mode.   Let’s take a look on how Import & Direct Query modes works One of the main advantages of using Power BI is its ability to import data from various online sources. To import data from your database directly into your Power BI reports and dashboards, you need to connect to the database first. Here are the steps to follow:  Open Power BI and click on the “Get Data” button. In the “Get Data” window, select the “Database” option. Choose SQL Server option. Enter the server name and credentials to connect to the database. Select the specific tables or views you want to import data from. Click on the “Load” button to import the data into Power BI or you can Transform the data if any necessary transformations or filters you wants to apply.   Setting Up a DirectQuery Connection Except for the import mode prompt, the steps for configuring a DirectQuery connection will remain the same. Choose the DirectQuery option when prompted for the import mode. Choosing the Right Mode The optimal mode hinges on your specific needs: Import Mode: When speed, offline access, and intricate data manipulation are paramount, Import mode shines. It fosters a responsive environment for in-depth analysis, ideal for creating reports and dashboards that can be explored without an internet connection. This mode is particularly advantageous for smaller to medium-sized datasets, where refresh times are manageable. DirectQuery Mode: This mode is your go-to for real-time insights. It ensures you're always basing your decisions on the freshest data available, minimizing the risk of outdated information influencing critical choices. For very large datasets, DirectQuery eliminates the memory limitations of Import mode, making it a powerful tool for handling massive volumes of information. By understanding the strengths and weaknesses of each mode, you can leverage Power BI effectively to make informed decisions based on your unique data analysis requirements.

Introduction  In the world of database management and querying, two commonly used methods are Language Integrated Query (LINQ) and Stored Procedures. Both serve the purpose of retrieving and manipulating data from databases, but they differ significantly in their approach and implementation. In this blog post, we'll delve into the disparities between LINQ and Stored Procedures to help you understand when to use each. 1. Conceptual Differences:    - LINQ Example:  var query = from p in db.Products                  where p.Category == "Electronics"                  select p;            foreach (var product in query)      {          Console.WriteLine(product.Name);      } In this LINQ example, we're querying a collection of products from a database context (`db.Products`). The LINQ query selects all products belonging to the "Electronics" category.    - Stored Procedures Example: CREATE PROCEDURE GetElectronicsProducts      AS BEGIN     SELECT * FROM Products WHERE Category = 'Electronics' END Here, we've created a Stored Procedure named `GetElectronicsProducts` that retrieves all products in the "Electronics" category from the `Products` table. 2. Performance:    - LINQ: LINQ queries are translated into SQL queries at runtime by the LINQ provider. While LINQ provides a convenient and intuitive way to query data, the performance might not always be optimal, especially for complex queries or large datasets.    - Stored Procedures: Stored Procedures are precompiled and optimized on the database server, leading to potentially better performance compared to dynamically generated LINQ queries. They can leverage indexing and caching mechanisms within the database, resulting in faster execution times. 3. Maintenance and Deployment:    - LINQ: LINQ queries are embedded directly within the application code, making them easier to maintain and deploy alongside the application itself. However, changes to LINQ queries often require recompilation and redeployment of the application.    - Stored Procedures: Stored Procedures are maintained separately from the application code and are stored within the database. This separation of concerns allows for easier maintenance and updates to the database logic without impacting the application code. Additionally, Stored Procedures can be reused across multiple applications. 4. Security:    - LINQ: LINQ queries are susceptible to SQL injection attacks if proper precautions are not taken. Parameterized LINQ queries can mitigate this risk to some extent, but developers need to be vigilant about input validation and sanitation.    - Stored Procedures: Stored Procedures can enhance security by encapsulating database logic and preventing direct access to underlying tables. They provide a layer of abstraction that can restrict users' access to only the operations defined within the Stored Procedure, reducing the risk of unauthorized data access or modification. Conclusion: In summary, both LINQ and Stored Procedures offer distinct advantages and considerations when it comes to querying databases. LINQ provides a more integrated and developer-friendly approach, while Stored Procedures offer performance optimization, maintainability, and security benefits. The choice between LINQ and Stored Procedures depends on factors such as application requirements, performance considerations, and security concerns. Understanding the differences between the two methods can help developers make informed decisions when designing database interactions within their applications.
