Asynchronous hierarchy-CodePudding

If I had an asynchronous method that contained an asynchronous method and a none asynchronous method in the parameters.

Which method would run first?

Example:

await ExampleMethod(
            Func<Task>: await Example.SomeMethod(), 
            Func<IEnumerable<T>> Example.SomeOtherMethod()
            );

There's nothing magic about asynchronous method invocations. They start executing synchronously, just like any other method (as I describe on my blog). Also, asynchrony doesn't impact the order of argument evaluation at all.

So, this code:

await ExampleMethod(await Example.SomeMethod(), Example.SomeOtherMethod());

is essentially the same as this code:

var parameter1 = await Example.SomeMethod();
var parameter2 = Example.SomeOtherMethod();
await ExampleMethod(parameter1, parameter2);
