fire and forget in csharp

Fire-and-forget is a programming pattern where a method is invoked and the caller does not wait for the method to complete before continuing execution. In C#, we can use the async and await keywords along with a Task object to implement fire-and-forget behavior.

To do this, we can define an async method and call it using the await keyword. This will allow the method to execute asynchronously and immediately return control to the caller. Here's an example:

main.cs
public async void DoSomethingAsync()
{
    await Task.Run(() =>
    {
        // Do some long-running task here
    });
}

// Call the method in a fire-and-forget manner
DoSomethingAsync();

In the example above, we define a method called DoSomethingAsync, which utilizes the Task.Run method to perform some long-running task in the background. The method is marked as async to indicate that it can be run asynchronously, and the void return type indicates that the method does not return anything.

To call the method in a fire-and-forget manner, we simply invoke it without the await keyword, as we're not interested in waiting for its completion. Instead, the method will execute in the background while the main thread continues to run.
