Fire-and-forget asynchronous methods in ASP.NET MVC
In ASP.NET MVC, "Fire-and-Forget" refers to the method of starting a task but not waiting for its completion. While this approach is generally not recommended for use in ASP.NET applications, it may be necessary in some cases, especially when dealing with asynchronous methods.

Using fire-and-forget for async methods can lead to unobserved exceptions. To mitigate this problem, you can:
