>I'm just getting started with the MM framework and have downloaded the latest install files and documentation (as of today). I have VS 2008, and SQL Server 2008. Install seemed to go flawless. (I should note that most of my development is VFP, and I am a newbie to VS 2008.) I'm walking through the developer documentation step by step and trying to run the sample app. I didn't have the Northwind database so I had to go download it separately and install/attach it. The database is now loaded and I can operate on it in SQL Server Management Studio. I open the sample app project (C#) and edit the connection string as the doc describes.

Your Solution has multiple projects in them. When you hit F5 to have Visual Studio "run" the app., it has to decide which one of the projects to run (it's perfectly valid to have both a WinForms app., a console app, and a web app inside of the same project). Currently, a class library project is set as the main "startup" app., which is why it's complaining (it can't "run" a class library). Right-click on the WinForms or ASP.NET web project and select "Set as Startup Project". You can see the one that's currently selected since the project name is bold. Then re-run and it should work as expected.
