dotnet build sln file failing in Windows

[livarcocc]

We have logs for this here: https://ci.dot.net/job/dotnet_cli/job/rel_1.0.0/job/debug_windows_nt_x86_prtest/450/consoleFull. Just search for stack trace.

I am going to zip up some projects that reproed this in windows and add it here in a second.

Just do

dotnet restore TestApp.csproj
dotnet build TestApp.sln

PJAppWithSlnAndXprojRefsAndUnrelatedCsproj.zip

I've also had issues of msbuild /t:restore on solution files where the error is "sequence contains more than one element".

This appears to happen (sporadically) when you build an sln file that references a csproj file that is also referenced as a project dependency by another csproj file.

In this case (see the callstack below) TestLibrary is referenced in the sln and also is a project dependency of another csproj file referenced in the sln file. This appears to be some sort of timing issue.

Note that this also fails on other platforms (not just Windows).

[srivatsn]

@nguerrera @rainersigwald - does this look the concurrency issue as well?

[rainersigwald]

Yes, I'd bet this is a dupe of #739.

[dsplaisted]

OK, closing this issue as a dupe of #739
