In C#7 there is an enhancement in the main method Async Main in C# that will allow you to await in your main method. Let me show you an example of how it was in C#6 and then how it has changed in C#7.
You will remember this most likely
|
1 2 3 4 |
static int Main() { return SomeAsyncCall().GetAwaiter().GetResult(); } |
One will need to get the Awaiter and then GetResult in order for it to work. But now in C#7 you can write it like below.
|
1 2 3 4 5 6 |
static async Task<int> Main() { Console.WriteLine("Helllo and delay"); await Task.Delay(2000); return await SomeAsynCall(); } |
And to add cherry to the icing, if you have a method that doesn’t return a value you can also just return Task.
|
1 2 3 4 5 6 |
static async Task Main() { Console.WriteLine("Helllo and delay"); await Task.Delay(2000); await SomeAsynCall(); } |
Summary
The above code shows the ease that C#7 provides with its main method an great improvement from C#6 I would say, hope that helps you in learning C#.
