It sounds like you don't get this error when building with the VS.Net IDE, but you do with Visual Build Professional? Have you invoked the command-line used by Visual Build Pro to determine whether it really is Visual Build Pro or the command-line compiler? To do so, just check the box "Display the compiler command-line that is used", then execute the displayed command-line call manually (noting the output).
If the error occurs when using the command-line compiler, the issue is related to the Microsoft compiler, otherwise please either post or send the following info to
support@kinook.com so we can trouble-shoot:
- bld file
- csproj file that causes the problem
- portion of the log indicating the error
