what is source code

BlazorServer is suitable for scenarios with low user volume, low latency and strong security. The core logic runs on the server side, dependent on the network but starts quickly; BlazorWebAssembly is suitable for scenarios with high scalability, offline use, and independent deployment. The code runs on the client side, and the first screen loads slowly but the interaction is smooth. 1. In terms of working principle, BlazorServer processes logic and pushes updates on the server through SignalR, while WebAssembly downloads .NET runtime in the browser and executes locally. 2. In terms of applicable scenarios, Server is suitable for projects with poor equipment performance and need to be launched quickly; WebAssembly is suitable for public network SaaS, PWA, and API driver architectures.

In C#, this keyword has four main uses. 1. Reference the current instance of the class to resolve conflicts between the fields and parameters, such as this.name assignment in the constructor; 2. Pass the current object as a parameter to other methods, such as OrderProcessor.Process(this); 3. Implement chain calls of the constructor through this to reduce duplicate code, such as the constructor with parameter without arguments; 4. Use this to modify the first parameter in the extension method to make the method look like an instance method, such as the WordCount extension method of type string.

When sending HTTPGET requests using HttpClient in C#, the instance should be multiplexed, the response should be processed correctly, and the request header should be added. It is recommended to create an HttpClient instance as a singleton or static field to avoid socket exhaustion; sending a GET request, you can use GetStringAsync to get string results or GetAsync to process status code and response content; you need to add authentication information such as APIKey through DefaultRequestHeaders; at the same time, you should pay attention to exception handling, set up BaseAddress to simplify URL management, and it is recommended to use IHttpClientFactory to manage client instances to optimize resources.

To create a Windows service, you need to use the ServiceBase class and follow the steps to implement it. 1. Create a WindowsService project in VisualStudio and inherit the ServiceBase class; 2. Write service logic such as timing tasks or listening operations in the OnStart() and OnStop() methods; 3. Add the installer component to set Account, ServiceName and StartType properties to register the service; 4. Use the installutil command to install or uninstall the service and check the service manager to confirm the registration status; 5. Debug by attaching a debugger or manually attaching it to the process. Mastering these steps can help you realize background task processing and

To optimize .NET garbage collection, you should first clarify whether to use ServerGC or WorkstationGC: ServerGC is suitable for multi-core server applications to improve throughput. The configuration method is to set "System.GC.Server":true in runtimeconfig.json; use it with caution in 1-2 core low-configuration environments. Secondly, select GC mode according to the delay requirements: Batch mode is suitable for high-throughput scenarios, Interactive is used for regular responsive services, LowLatency mode can temporarily reduce pause time, but exit in time after use to prevent memory overflow. Next, understand the intergenerational recycling mechanism to avoid short-lived life cycle objects
