Can the Main entry-point function be async?

Question

I'm using .NET Framework, and I'm wanting to call an awaitable function in my Main entry-point function.

I'm using the async keyword on the function, but it keeps giving me CS5001 Program does not contain a static 'Main' method suitable for an entry point. Although it doesn't say anything about it not being async.

It seems this error is related to the problem.

Have a read through the answer on the duplicate question there are some really handy ones which explain how to achieve what you are after — Izzy, Aug 13 '19 at 10:40

Async Main methods were introduced with C#7.1, so if you are targeting that or above, you can use it.

You can't set `async` modifier on the Main method of a console app which is what the error in OPs question refers to. – Adrian Aug 13 '19 at 10:40

@Adriani6 actually you can - starting with C# 7.1 https://blogs.msdn.microsoft.com/benwilli/2017/12/08/async-main-is-available-but-hidden/ – Alex Wiese Aug 13 '19 at 10:43

@Adriani6 In 7.1 you should be able to. – Magnus Aug 13 '19 at 10:43
