How to Call a Synchronous Method Asynchronously in C#?

The simplest way to execute a method asynchronously is to start executing the method by calling the delegate's BeginInvoke method, do some work on the main thread, and then call the delegate's EndInvoke method. EndInvoke might block the calling thread because it does not return until the asynchronous call completes.

Can we call synchronous method from another asynchronous method?

Yes, We can call a synchronous method inside a future method. Both will run on Asynchronous Only.

How do you make a synchronous function asynchronous?

The first step is to make this function return a promise instead. Now, let's look at how this would actually be used. I'll start with the synchronous version. To use the asynchronous version, however, we either need to convert the callback within createServer into an Async/Await function or now use a promise chain.
