How can I improve the performance of my ASP.NET application using async programming?

How can I improve the performance of my ASP.NET application using async programming?

You can improve performance by using async and await keywords to free up threads while waiting for I/O operations.

Can you give me an example of how to implement async in a controller?

Sure! In your controller action, you can define it as async and return a Task. For example: public async Task<IActionResult> GetData().

What about database calls? Should I use async there too?

Absolutely! Use async methods like ToListAsync() or SaveChangesAsync() to avoid blocking the thread during database operations.

Are there any downsides to using async programming?

Yes, it can add complexity to your code and may lead to issues if not handled properly, such as deadlocks.
