#Understanding_the_Common_Language_Runtime(CLR) The Common Language Runtime (CLR) is the heart of the .NET framework, responsible for managing the execution of .NET programs. Here’s a look at how CLR functions: 1. #Compilation_and_Execution:- #Compilation: When you write code in C#, VB.NET, or any .NET language, it's compiled into Intermediate Language (IL), also known as MSIL (Microsoft Intermediate Language) or CIL (Common Intermediate Language). This IL is platform-independent and is not directly executable by the CPU. #Execution: At runtime, the IL code is compiled by the CLR's Just-In-Time (JIT) compiler into native machine code that the CPU can execute. This compilation happens on-demand and ensures that the code runs efficiently on the specific hardware. 2. #Memory_Management: #Garbage_Collection: CLR includes a garbage collector that automatically manages memory by reclaiming unused objects. This prevents memory leaks and helps maintain application stability and performance. #Memory_Allocation: CLR provides services for allocating and deallocating memory efficiently, optimizing memory usage throughout the application's lifecycle. 3. #Exception_Handling:- CLR provides robust mechanisms for handling exceptions that occur during program execution. This includes structured exception handling using try-catch-finally blocks, ensuring reliable error management and program stability. 4. #Security:- CLR enforces code access security policies, which restrict the actions that code can perform to protect the system and its resources. Security checks are performed during JIT compilation and at runtime, ensuring that code operates within defined security boundaries. 5. #Type_Safety_and_Verification: - Before JIT compilation, CLR performs type verification to ensure that IL code accesses only valid memory locations and adheres to type safety rules. This prevents common programming errors that could lead to crashes or security vulnerabilities. 6. #Interoperability: - CLR facilitates interoperability between .NET code and unmanaged code (such as C or C++), COM components, and other systems. It provides mechanisms like Platform Invocation Services (P/Invoke) and COM Interop to enable seamless integration. 7. #Execution_Environment: - CLR provides a managed execution environment where .NET applications run. It abstracts the underlying hardware and operating system, providing a consistent runtime environment across different platforms (Windows, Linux via .NET Core, etc.).

📢 𝗦𝗲𝘁𝘂𝗽 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗲 𝗰𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻 𝗳𝗶𝗹𝗲𝘀 𝗳𝗿𝗼𝗺 𝘀𝗰𝗿𝗮𝘁𝗰𝗵 𝗶𝗻 .𝗡𝗲𝘁 👉 In ASP.NET Core, the WebApplicationBuilder class is utilized to initialize your application. During this initialization process, 𝗪𝗲𝗯𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝗕𝘂𝗶𝗹𝗱𝗲𝗿 generates a 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻𝗠𝗮𝗻𝗮𝗴𝗲𝗿 instance and makes it accessible through the 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻 𝗽𝗿𝗼𝗽𝗲𝗿𝘁𝘆. 👉 WebApplicationBuilder adds several default configuration providers to the ConfigurationManager  ✔️ JSON file provider  ✔️ User Secrets  ✔️ Environment Variable  ✔️ Command-line arguments 🔥 The Configuration Manager is automatically set up with these sources, but you can easily add additional providers. 🚀Alternatively, you can start from scratch by clearing the default providers, as demonstrated in the slide, allowing you to fully customize the configuration sources. In .NET, you can use a variety of configuration sources to manage your application’s settings. You can also use third-party configuration provider or add your own custom configuration provider. Fundamentally, it allows you to aggregate configuration values from multiple sources into a single, cohesive object. ✅ 𝗯𝘂𝗶𝗹𝗱𝗲𝗿.𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻.𝗦𝗼𝘂𝗿𝗰𝗲𝘀.𝗖𝗹𝗲𝗮𝗿() By calling Clear(), you remove all the previously added configuration sources. This can be useful if you want to start with a clean slate and add only specific configuration sources afterward. ✅ 𝗯𝘂𝗶𝗹𝗱𝗲𝗿.𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻.𝗔𝗱𝗱𝗫𝗺𝗹𝗙𝗶𝗹𝗲("𝗽𝗮𝘁𝗵",𝗼𝗽𝘁𝗶𝗼𝗻𝗮𝗹:𝘁𝗿𝘂𝗲,𝗿𝗲𝗹𝗼𝗮𝗱𝗢𝗻𝗖𝗵𝗮𝗻𝗴𝗲:𝘁𝗿𝘂𝗲); 1️⃣ 𝗣𝗮𝘁𝗵: Specify the path of the file. 2️⃣ 𝗼𝗽𝘁𝗶𝗼𝗻𝗮𝗹: true, telling the configuration provider to skip files that it can’t find at runtime instead of throwing 𝗙𝗶𝗹𝗲𝗡𝗼𝘁𝗙𝗼𝘂𝗻𝗱𝗘𝘅𝗰𝗲𝗽𝘁𝗶𝗼𝗻. 3️⃣ 𝗿𝗲𝗹𝗼𝗮𝗱𝗢𝗻𝗖𝗵𝗮𝗻𝗴𝗲: 𝘁𝗿𝘂𝗲: This means that if the configuration file is modified while the application is running, the configuration will automatically reload to reflect the changes. This is useful for scenarios where you want the application to adapt to configuration changes without needing a restart. 4️⃣ 𝗿𝗲𝗹𝗼𝗮𝗱𝗢𝗻𝗖𝗵𝗮𝗻𝗴𝗲: 𝗳𝗮𝗹𝘀𝗲: If set to false, the configuration will not reload automatically when the file changes. Any changes to the configuration file will only take effect after the application is restarted. ❓ Have you ever added a configuration file manually?

𝐌𝐚𝐬𝐭𝐞𝐫𝐢𝐧𝐠 𝐅𝐥𝐮𝐞𝐧𝐭 𝐀𝐏𝐈 𝐢𝐧 𝐀𝐒𝐏.𝐍𝐄𝐓 𝐂𝐨𝐫𝐞: 𝐒𝐢𝐦𝐩𝐥𝐢𝐟𝐢𝐞𝐝 𝐂𝐨𝐧𝐟𝐢𝐠𝐮𝐫𝐚𝐭𝐢𝐨𝐧𝐬 𝐟𝐨𝐫 𝐂𝐨𝐦𝐩𝐥𝐞𝐱 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞𝐬 As part of my experience, while implementing an ASP.NET Core project, I learned the power of Fluent API and how it can be used for complex database configurations. 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐅𝐥𝐮𝐞𝐧𝐭 𝐀𝐏𝐈? Fluent API is a way to configure your database in Entity Framework Core. It allows you to define database rules using code in the 𝐎𝐧𝐌𝐨𝐝𝐞𝐥𝐂𝐫𝐞𝐚𝐭𝐢𝐧𝐠 method of your 𝐃𝐛𝐂𝐨𝐧𝐭𝐞𝐱𝐭. 𝐖𝐡𝐞𝐧 𝐭𝐨 𝐔𝐬𝐞 𝐅𝐥𝐮𝐞𝐧𝐭 𝐀𝐏𝐈 𝐌𝐨𝐫𝐞 𝐅𝐥𝐞𝐱𝐢𝐛𝐢𝐥𝐢𝐭𝐲: 𝐅𝐥𝐮𝐞𝐧𝐭 𝐀𝐏𝐈 𝐨𝐟𝐟𝐞𝐫𝐬 𝐦𝐨𝐫𝐞 𝐟𝐥𝐞𝐱𝐢𝐛𝐢𝐥𝐢𝐭𝐲 𝐭𝐡𝐚𝐧 𝐃𝐚𝐭𝐚 𝐀𝐧𝐧𝐨𝐭𝐚𝐭𝐢𝐨𝐧𝐬. It's used for complex configurations that Data Annotations can’t handle. 𝐀𝐝𝐯𝐚𝐧𝐜𝐞𝐝 𝐑𝐞𝐥𝐚𝐭𝐢𝐨𝐧𝐬𝐡𝐢𝐩𝐬: Use Fluent API to set up complex relationships, such as many-to-many or composite keys. 𝐊𝐞𝐞𝐩𝐬 𝐌𝐨𝐝𝐞𝐥𝐬 𝐂𝐥𝐞𝐚𝐧: Fluent API separates configuration code from the model class, keeping the model focused on business logic. 𝐎𝐯𝐞𝐫𝐫𝐢𝐝𝐞𝐬 𝐃𝐚𝐭𝐚 𝐀𝐧𝐧𝐨𝐭𝐚𝐭𝐢𝐨𝐧𝐬: If you use both Data Annotations and Fluent API, Fluent API will override any conflicting configurations. 𝐂𝐮𝐬𝐭𝐨𝐦 𝐓𝐚𝐛𝐥𝐞 𝐚𝐧𝐝 𝐂𝐨𝐥𝐮𝐦𝐧 𝐍𝐚𝐦𝐞𝐬: You can use Fluent API to define custom table and column names that don’t follow EF Core's default conventions. 𝐈𝐧𝐝𝐞𝐱𝐞𝐬 𝐚𝐧𝐝 𝐂𝐨𝐧𝐬𝐭𝐫𝐚𝐢𝐧𝐭𝐬: Fluent API allows you to create indexes or apply unique constraints, which are not possible using Data Annotations alone. 𝐂𝐨𝐦𝐩𝐥𝐞𝐱 𝐂𝐨𝐧𝐟𝐢𝐠𝐮𝐫𝐚𝐭𝐢𝐨𝐧𝐬: Fluent API is great for configuring things like foreign keys with custom names, or setting cascade delete behaviors. 𝐖𝐨𝐫𝐤𝐬 𝐰𝐢𝐭𝐡 𝐌𝐢𝐠𝐫𝐚𝐭𝐢𝐨𝐧𝐬: Even if you use Fluent API, you still need to use migrations to apply the configurations to your database. 𝐋𝐚𝐫𝐠𝐞 𝐏𝐫𝐨𝐣𝐞𝐜𝐭𝐬: Fluent API is especially helpful in larger projects where database configurations are more complex and may change often. 𝐒𝐞𝐩𝐚𝐫𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐂𝐨𝐧𝐜𝐞𝐫𝐧𝐬: Fluent API allows better organization by keeping database configurations out of the model classes, leading to cleaner code. 𝐄𝐱𝐚𝐦𝐩𝐥𝐞: protected override void OnModelCreating(ModelBuilder modelBuilder) { modelBuilder.Entity<Student>() .HasKey(s => s.StudentId); // Primary key modelBuilder.Entity<Student>() .Property(s => s.Name) .HasMaxLength(50) // Max length .IsRequired(); // Required field modelBuilder.Entity<Student>() .HasOne(s => s.Class) .WithMany(c => c.Students) .HasForeignKey(s => s.ClassId); // Foreign key }    Fluent API has given me more control over database configurations while keeping my code clean and organized. I’d love to hear your thoughts or experiences with Fluent API—how do you use it in your projects? #ASPNetCore #EntityFrameworkCore #FluentAPI

✨ Tracking Change in Data in ASP.Net core web API and Log it in Database

٥٨

Logging in ASP.NET Core is a powerful service that allows developers to capture various application behavior and errors. It’s an essential component for monitoring, debugging, and the operational management of applications. Logging can capture information such as errors, system information, and custom messages. uses of logging some uses of logging are for debugging and troubleshooting Event recording monitoring and performance analysis there are different components of logging which are Log Levels: These categorize the severity of the logged events, such as DEBUG, INFO, WARN, ERROR, and FATAL. Log levels help filter logs based on their importance. Log Messages: The actual information recorded, often including a timestamp, event description, and potentially user or session identifiers. Log Output: The destination for log messages, which could be a console, a file, a database, or a centralized log management solution. Log Frameworks: Many web applications utilize logging frameworks or libraries that provide a standardized approach to logging. These frameworks offer flexibility in configuration, log formatting, and output options. Examples include Log4j for Java applications, Serilog or NLog for .NET applications, and Winston or Morgan for Node.js applications. Log levels: ASP.NET Core provides a set of log levels to help developers categorize and prioritize log messages based on their severity and importance. These log levels are defined in the Microsoft.Extensions.Logging namespace and are commonly used across ASP.NET Core applications the various log levels are explained below Trace: The most detailed log level. It is typically used for very detailed debugging information that can be useful during development but may be too verbose for production environments. Debug: Used for messages that are helpful during development and debugging but are not necessary in production environments. Information: General information messages that can be helpful in tracking the flow of the application. These messages are typically used to record significant application events. Warning: This indicates a potential problem or issue that does not prevent the application from running but should be investigated. These messages highlight issues requiring attention but do not necessarily indicate an error. Error: This is used to log errors that occur during the execution of the application. These messages indicate problems that need to be addressed but do not necessarily result in the termination of the application. Critical: The most severe log level. Used to log critical errors that may result in the termination of the application or significant data loss. These messages indicate serious problems that require immediate attention. None: Disables logging. No log messages will be generated when this level is set

ASP .Net Core Basic Program Execution Program.Cs file basic code And Detail // Create a builder instance of WebApplicationBuilder class var builder = WebApplication.CreateBuilder(args); // Build the app (Return an instance of WebApplication) var app = builder.Build(); // Create a route - HTTP GET method + URL, returns "Hello World" app.MapGet("/", () => "Hello World!"); // Start the server app.Run(); When we start the execution of our ASP.NET console application, it begins from the `Program.cs` file. This file typically contains the `Program` class and the `Main` method. However, starting with C# 9, Microsoft removed the need for the `Program` class and the `Main` method. Instead, they introduced a simplified approach, and the application can now run with just four lines of code. Details about each line of code are provided in the comments above the code. Detail of each line: code Line 1 // Create a builder instance of WebApplicationBuilder class var builder = WebApplication.CreateBuilder(args); This line creates an instance of WebApplicationBuilder, which sets up configuration, logging, and services for the application. Code Line 2 // Build the app (Return an instance of WebApplication) var app = builder.Build(); After configuring services and middleware, you build the app using builder.Build(). This creates a WebApplication instance that is ready to run. Code Line 3 // Create a route - HTTP GET method + URL, returns "Hello World" app.MapGet("/", () => "Hello World!"); Here, you define a simple route using the MapGet() method. This maps the root URL ("/") to an HTTP GET request, which returns the string "Hello World!". Code Line 4 // Start the server app.Run(); Finally, the app.Run() method starts the web server, allowing it to listen for incoming requests.

Why Implement API Versioning? It allows you to support different versions of your API simultaneously. It enables you to safely introduce new features or changes without disrupting existing users. Here is an example of using API Versioning in ASP.NET Core Web API: 1- Install the NuGet Package: dotnet add package: Microsoft.AspNetCore.Mvc.Versioning 2- Configure API Versioning: In the ConfigureServices method, add the following services.AddApiVersioning(options => { options.ReportApiVersions = true; // Reports supported API versions in response headers options.AssumeDefaultVersionWhenUnspecified = true; // Uses the default version if not specified options.DefaultApiVersion = new ApiVersion(1, 0); // Sets the default API version }); 3- Create Versioned Controllers: Copy your existing controller and add the ApiVersion attribute. Also, update the Route attribute to reflect the version, as shown in the snapshots. 4- Test the API Versioning by calling the two different versions of your API: Version 1.0: GET /api/v1/products Version 2.0: GET /api/v2/products

Title: Domain-Driven Design (DDD) for Microservices: A Strategic Guide 🔰 Understanding DDD: Domain-Driven Design (DDD) is a software development approach focusing on understanding and modeling the core domain. It bridges the gap between technical and domain experts, ensuring that both are aligned with the software’s goals. 🔰 DDD in Modern Software Development: With the shift towards microservices, DDD becomes crucial. It ensures services are well-defined, isolated, and capable of independent evolution, thus enhancing agility and scalability. Key Concepts 🗝 : • Entities: Unique objects with a distinct lifecycle. • Value Objects: Immutable objects representing descriptive characteristics. • Aggregates: Clusters of related objects treated as a single unit to maintain consistency. 🔰 DDD Patterns in Microservices: 1️⃣ Bounded Contexts: Define clear subsystem boundaries. 2️⃣ Repositories: Abstract the database layer. 3️⃣ Factories: Create complex objects. 4️⃣ Services: Focus on specific business logic. 🔰 Relationship between DDD and Microservices: DDD’s strategic perspective complements microservices’ need for small, manageable, independent services. By dissecting complex domains into subdomains, businesses can create microservices with clear purposes and responsibilities. 🔰 Ensuring Autonomy and Isolation: Microservices must function autonomously. DDD helps achieve this by minimizing dependencies, allowing services to evolve independently. 🔰 CQRS and Event Sourcing: 🔸 CQRS: Separates command and query operations, optimizing each for its specific purpose. 🔸 Event Sourcing: Stores every state change as an event, ensuring data isn’t lost and system state is traceable. 🔰 Challenges and Solutions: 🔸 Complexity: Breaking down systems into bounded contexts requires clear domain knowledge. 🔸Scalability and Consistency: Event-driven architecture and CQRS can help manage data integrity and optimize scalability. 🔰 Implementing DDD for Microservices: 1️⃣ Understand the Domain: Collaborate with domain experts to identify key concepts. 2️⃣ Define Bounded Contexts: Ensure each microservice has a clear responsibility. 3️⃣ Use DDD Patterns: Apply entities, value objects, aggregates, and repositories. 4️⃣ Adapt Architecture: Embrace iterative development and adapt to evolving business needs. 5️⃣ Foster Collaboration: Promote open communication and feedback loops. 🤘 Conclusion: Integrating DDD with microservices leads to more responsive, adaptable, and maintainable systems. For successful implementation, businesses should invest in understanding DDD concepts, maintain clear communication, and prioritize training. By strategically combining DDD with microservices, companies can design systems that cater to current needs and are prepared for future challenges. ♻ #DDD #DomainDrivenDesign #Microservices #SoftwareDevelopment #Backend
