I'm looking at my Visual Studio .sln file as I'm customising build configurations (the reason why is a long story involving projects that won't load in VS2012).

Does anyone know what the Build.0 part of the build config section means? Does it mean that this project is ticked to be built under this build configuration?

Also, what does the ActiveCfg relate to?

{CFHHHA78-C688-40B3-B53A-20C963A6F138}.Debug|Any CPU.ActiveCfg = Debug|Any CPU
{CFHHHA78-C688-40B3-B53A-20C963A6F138}.Debug|Any CPU.Build.0 = Debug|Any CPU
{CFHHHA78-C688-40B3-B53A-20C963A6F138}.Debug|Mixed Platforms.ActiveCfg = Debug|AnyCPU
{CFHHHA78-C688-40B3-B53A-20C963A6F138}.Debug|x86.ActiveCfg = Debug|Any CPU

Any links to .sln file walkthroughs would also be welcome. As always, the MSDN .sln file explanation is a little cryptic and doesn't seem to fully explain this part of the sln file.

Yes, your hunch was right. It does mean that the project has its Build option ticked to build under the build configuration. I just tested this by opening the solution in one instance of Visual Studio and the .sln file in the text editor (open with) of another Visual Studio instance. If you change the configuration options in the first and save all, you will see the appropriate changes in the second.
