描述

I loaded a csproj using MSBuildWorkspace but the project.MetadataReferences was empty. The project compiles and runs fine in VS2015 and has numerous (+15) third party references. I discovered that the project had the default configuration Debug|AnyCPU, which did not exists, so i fixed it to an existing configuration and the project now loads fine.

I do not understand this behaviour, it seems like a bug to me, or that there should be some sort of exception thrown.

研究方向
Investigate the MSBuildWorkspace loading logic in Roslyn, specifically how it resolves project configurations. Look at the code in 'src/Workspaces/Core/Portable/Workspace/MSBuildWorkspace.cs' and related files. Understand why a non existent default configuration causes metadata references to be skipped. Consider adding a validation or error message when the default configuration is missing. Also review the StackOverflow link provided for additional context.
