How Can I Achieve Synchronous-like Behavior with .NET's Asynchronous `Process.Start`?

Asynchronous Process Execution: Exploring Equivalents to Process.Start

Process.Start, a fundamental function in .NET, empowers developers to execute external applications and batch files. While this action is notably straightforward, it operates asynchronously, rendering it unsuitable for certain scenarios where synchronous execution is preferred.

To bridge this gap and enable effective usage of async/await patterns for process execution, several approaches can be contemplated.

1. Wrapping Process.Start in a Task.Run

One viable option is to wrap Process.Start within a Task.Run. This approach allows for the asynchronous initiation of the process, but it comes with a caveat: there's no way to determine when the process has completed. Hence, this solution may not meet all requirements.

2. Employing the Exited Event and TaskCompletionSource

For scenarios demanding more control, the Exited event can be combined with a TaskCompletionSource. This approach allows for registering a callback that fires when the process concludes. The callback then triggers the completion of the TaskCompletionSource, which in turn concludes the async await operation.
