Description James Bellinger 2012-07-08 13:31:20 UTC
See http://msdn.microsoft.com/en-us/library/hh156513%28v=vs.110%29.aspx for 'async keyword should be contextual'.

I was using it as 'bool async' parameter and then later as 'async ? a : b' and the Mono compiler has a problem with this latter use, saying:

Test/System.IO.Pipes/PipeSecurityTest.cs(177,38): error CS0103: The name `Async' does not exist in the current context

Notice it also alters the casing...

I cannot reproduce the issue

my sample compiles fine with 2.11

class C
{
	public static void Foo (bool async)
	{
		int a = 0;
		int b = 2;
		var r = async ? a : b;
	}
	
	public static void Main ()
	{
	}
}

System.Core/Test/System.IO.Pipes/PipeSecurityTest.cs is where I was running into this issue.

If you replace the four @async with async you will encounter it.
