Is there a standard file extension for MSBuild files?

Question

Is there a standard file extension for MSBuild files that are not project files but instead more complex build scripts?

I was thinking .msbuild.proj to avoid confusi

Answer 1

I recommend what VS does:

.*proj for project files --- msbuild.exe will find them automatically if they match this pattern
.targets for build process --- generally imported towards the end of your project
.props for shared settings --- generally imported towards the top of your project. C++ (*.vcxproj) files use these, and they will doubtless get added to VB and C# default project files at some point.
