ProjectRootElement.Open throws due to missing

Issue Description

When try to open csproj project file with ProjectRootElement.Open from namespace Microsoft.Build.Construction then it throws following exception. I couldn't find 4.0.4.1 version anywhere, and my attempt to solve with bindingRedirect didn't work, it's blocking my work for another P1 issue.
error: Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. trace: System.AggregateException: One or more errors occurred. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

@benvillalobos
I don't, I'm just using VS to debug nuget client code.
