Question

I try to install Async CTP and it says that installation was completed successfully, but nothing installs into “My Documents” and i cant find the samples. What can be done to see the samples with libraries and try them?

Answer 1

Do you have another machine you can install on at all?

My netbook didn’t accept the CTP installation properly, but it did do enough magic to the C# compiler to make that part work. I then just copied AsyncCtpLibrary.dll from another machine where the installation had worked, and all was fine. If you want to copy the samples as well, I’m sure they’d work too.

If this turns out to be a common problem, I suggest we ask for permission to publish a zip file with the samples and library.

Here’s a short program to let you see if you’ve got the C# compiler bits installed:

public class Test
{
    static async void Main() {}
}

That should fail with an error like this:

Test.cs(4,22): error CS0656: Missing compiler required member
        'System.Runtime.CompilerServices.VoidAsyncMethodBuilder.Create'
Test.cs(4,22): error CS1993: Cannot find Task-related types. Are you missing a
        reference to 'AsyncCtpLibrary.dll' ?
Test.cs(4,22): warning CS1998: This async method lacks 'await' operators and
        will run synchronously. Consider using the 'await' operator to await
        non-blocking API calls, or 'await TaskEx.Run(...)' to do CPU-bound work
        on a background thread
