Hey there! Today, I’m sharing some straightforward ways to speed up your .NET Core apps. No fancy words, just simple stuff that works.

Let’s dive in!

1. Asynchronous Programming

Asynchronous programming in .NET Core is a powerful way to enhance the scalability and responsiveness of your applications.

It allows your program to handle other tasks while waiting for operations, like I/O processes, to complete.

When to Use Asynchronous Programming:

  • I/O Bound Operations: Use async programming for operations that involve data access, file reading/writing, network calls, etc., where the program waits for an external process to complete.
  • UI Responsiveness: In desktop applications, use async to keep the UI responsive during long-running tasks.
  • Scalability in Web Applications: Use async in web applications to handle more requests by freeing up threads while waiting for database queries or API calls.

Best Practices:

  • Use ConfigureAwait(false) when awaiting tasks in a library to avoid deadlocks.
