Terry, Are you using the correct msbuild executable? The msbuild tag allows you to specify the msbuild executable to use, however it isn't a required parameter. If it is not specified, it will use the .NET 2.0 framework executable. It sounds like you need to set the tag to use the msbuild executable in the .NET 3.5 framework folder. (C:\WINDOWS \Microsoft.NET\Framework\v3.5\msbuild.exe)
