NuGet package broken in Unity 2021.3.6f1

[fdorothy]

I'm trying to install the NuGet package Microsoft.ML.Probabilistic.Compiler in Unity 2021.3.6f1 via NuGetForUnity (https://github.com/GlitchEnzo/NuGetForUnity). I am seeing the following errors immediately after installing:

It looks like the depedency Systyem.CodeDom is conflicting with the system libraries?

There is no conflict since .NET performs assembly unification of these assemblies. The nuget package works perfectly fine outside of Unity. So this looks like a misbehavior of Unity. Check for any binding redirects that you have defined that might be messing things up.
