The relevant links for the July CTP of .NET Framework 3.0 and the associated VS Extensions for Window Workflow Foundation (WF) RC4 are below:
- .NET Framework 3.0 July CTP from here.
- VS Extensions for WF RC4 from here.
- Windows SDK for July CTP from here.
If you are just starting with WF you should install this build. There are no new features or API changes between RC2 and RC4, only some bug fixes. Before you ask, I don’t have a list.

there was a post about this issue (I don't remember where); the solution was to store the setup (.exe) file in different directories, and to run them from there...otherwise the setup for the VS extens ion calls your sdk setup...

I'm really confused with all the RC versions and the Beta versions, and the WinFX and .NET 3.0 stuff.
what do I exactly need to develop WF applications
what do I exactly need to run WF applications
I developed workflows as well as a workflow Runtime Service on my local machine. Now I have to deploy it in the integrative system, and the system won't work. I am not sure, which version of which Framework and so on I need to install on the integrative machine.
I still use the Beta 2.2 version, because I'm still bit confused, and dont want to update until I know exactly what to update, deinstall and so on.
Do I need to deinstall the WinFX, Workflow Extensions for VS and so on
Please help. Thanks.
