Using MSBuild on the command line and building to any platform/target possible?

[Vurv78]

Is it possible to use MSBuild on the command line for a .sln without specifying the platform / configurations (/p:Configuration=Debug or /p:Platform="Any CPU" for example)?

I am trying to automate this and am going through many different solutions which all have different configurations, so I can't just specify one as many projects won't have it and will lead to this error:

The specified solution configuration "...|..." is invalid.
Please specify a valid solution configuration using the Configuration and Platform properties ...

Basically, if a solution has many targets such as Release|x64, Debug|Any CPU then I just want MSBuild to pick the first one applicable to build without me specifying it.

You don't have to specify a configuration--MSBuild will pick the first one defined in the solution.
