Jeff,

>The type 'OakLeaf.MM.Main.Business.mmBaseBusinessObject' is defined in an assembly that is not referenced. You must add a reference to assembly 'Mere Mortals Framework 2005, Version=2.0.0.0, Culture=neutral, PublicKeyToken=511bd18e16c7f771'.

>When I try to build one of my projects. Obviously, it is telling me I haven't referenced the MM Framework. I have it referenced. When I remove it, I get an error for each form complaining that the using statement for OakLeaf.MM.Main.Business is not found ("are you missing an assembly reference?").

Is it possible you have multiple versions of the MM .NET assemblies on your computer? I recommend launching Windows Explorer and navigating to the C:\Windows\Assembly (or C:\WINNT\Assembly) and check if there are multiple versions. Another thing to check...see if you inadvertently have local copies of MM .NET assemblies in your application's bin\Debug folder.

Best Regards,
