Unity3d project crashes VSCode

Question

Medium-size Unity3d project. Opens fine in VSCode on OS X, opening it in VSCode on Windows results in deep freeze (and crash).

What I found so far: Unity3d creates .csproj files with target .Net framework "v2.0". Target persists between development environments. OmniSharp logs lots of warnings like:

[WARNING:OmniSharp.MSBuild.MSBuildProjectSystem] The primary reference "System.Xml.Linq" could not be resolved because it has an indirect dependency on the framework assembly "System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v2.0". To resolve this problem, either remove the reference "System.Xml.Linq" or retarget your application to a framework version which contains "System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089".

Manually switching target framework to "v3.5" in .csproj files resolves warnings and avoids VSCode freeze, but as soon as I add new file to project Unity regenerates .csproj files.

Any ideas why it works on Mac, but refuses to work (without modifications) on Windows?

Answer 1

Solved it. Turns out it was integration plugin that switched target framework to "v2.0" from Unity's default (and working) "v3.5".
