Noteworthy from the source: Microsoft does NOT use (unmergable) SLN-files for their projects, but instead scripts-msbuild invocations against specific projects:

Noteworthy from the source: Microsoft does NOT use (unmergable) SLN-files for their projects, but instead scripts-msbuild invocations against specific projects: https://github.com/dotnet/coreclr/blob/master/build.cmd#L140 https://github.com/dotnet/coreclr/blob/master/build.cmd#L140 https://github.com/dotnet/coreclr/blob/master/build.cmd#L159 https://github.com/dotnet/coreclr/blob/master/build.cmd#L159 I guess this explains why they saw no need to fix the somewhat broken SLN file-format in the first place, but actually did something about project-files. They don't share their customers pain on this point.
