Using Make VS.Net gives error message "..not a valid solution file

[megha_3781]

Hi,

Iam using Visual Build Professional 5.0.
Recently we installed Visual Studio 2005.
We created a project in c#. Now I want to build the
solution by using Make VS.Net.
It is saying my project file xyz.sln is not a valid Visual Studio .NET Solution file.
There is no issue with the solution file. It is fine.
I don't know why this message is coming. Whether Visual Build Professional 5.0
supports VS.Net to build Visual Studio 2005 solution project?

Actually I also tried using VISSTUDDIR\devenv.exe "filename" /build to build. This works fine but I don't know how to set Company Name,Product Version..etc.
