How do I use the Result from a CodeActivty<string> in WF 4.0?

Question

I've created a custom activity in a .NET 4.0 beta 1 WF project. It's defined as:

public class GetCurrentUserMailAddress : CodeActivity<string>

because I've read that this is the most efficient way of returning a single result.

At the end, I set the Result using:

context.SetValue(Result, up.EmailAddress);

But now I'm struggling to use it in my Workflow. I want to use the value in my next activity but I can't find it.

How do I reference the Result from one custom activity in the next activity?

Answer 1

Never mind. I was being thick. Just in case anyone else is struggling, the Properties window for the custom activity contains a Result property. Stick your variable name in there and it will be populated with the value of your Result OutArgument.
