Just the other day (February 27), pattern & practices released the Web Service Software Factory Modeling Edition for Visual Studio 2008. This is great news!

To get it up and running I installed the following tools:

• Visual Studio 2008 SDK Version 1.0 (this is needed because it contains the DSL Toolkit).
• Guidance Automation Extensions (February 2008) and Guidance Automation Toolkit (February 2008) Notice that the toolkit is only needed if you want to work with the source code of software factories.
• Web Service Software Factory Modeling Edition

I had problems with the installation of GAX where the setup complained that it couldn't find GuidanceAutomationExtensions[1].msi and there wasn't any file with that name. I solved it by simply make a copy of GuidanceAutomationExtensions.msi and rename it. The great thing about this new installation though is that we finally do not need to uninstall the previous version before installing the new one. This has been a hugh problem when upgrading before, because it is not possible to uninstall GAX without uninstalling all the software factories first.

Notice that it is important to read and follow the instructions in the InstallationInstructions.pdf.
