When all of the projects in a solution are of the same type (e.g. C#/VB projects) the solution configurations will match up exactly with the project configurations. Once you have projects in a solution that have mismatched configurations/platforms, Visual Studio creates the solution level configuration(s) "Mixed Platforms/Debug" and possibly "Mixed Platforms/Release". These configurations are just mappings to individual project level configurations.

For example, if you have a C# project and a C++ project, typically "Mixed Platforms/Debug" will map to "Any CPU/Debug" for the C# project and "Win32/Debug" for the C++ project.
