I am walking through the MS Press Windows Workflow Step-by-Step book and in chapter 8 it mentions a tool with the filename "wca.exe". This is supposed to be able to generate workflow communication helper classes based on an interface you provide it. I can't find that file. I thought it would be in the latest .NET 3.5 SDK, but I just downloaded and fully installed, and it's not there. Also, some MSDN forum posts had links posted that just go to 404s. So, where can I find wca.exe?

Should be part of the .NET 3 SDK (and later version as well). If you've already installed this, the path might look something like

C:\Program Files\Microsoft SDKs\Windows\v6.0\Bin\wca.exe

On my machine, with Visual Studio 2008 installed, it's in C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin
