Hello, Linda

Somewhere you have references to both versions of MM. First, check your projects and be sure that (for each MM assembly) you're only pointing to the most recent version. If that doesn't work, I'd suggest using VS tools (see help on gacutil options to dump a list of GAC'd assemblies, or use the .NET Framework configuration tool) to see how many versions of the assemblies are in the GAC and remove the ones that aren't needed.

Hope that helps,

>I created a new web project using VS 2005 and Mere Mortals 2.1, following the guidelines in the help file. I used business objects created under VS 2003 and then converted to VS 2005. When I try to build the solution, I get the same error for factory.cs and app.cs:
