System.TypeLoadException when compiling html

[DrHeinzDoofenshmirtz]

Hi.

I get the follow error when I try to do a Razor.Compile in an Azure Function App.

System.TypeLoadException: 'Method 'CreateAnalyzerDriver' in type 'Microsoft.CodeAnalysis.CSharp.CSharpCompilation' from assembly 'Microsoft.CodeAnalysis.CSharp, Version=3.8.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.'

This is how I do the compile:
var template = Razor.Compile(html, alc);

I am having a bunch of errors trying to execute the compilation from an Azure Function App.
Before this, I was having issues because Function Apps create a special bin sub-folder when building the project, and I had to add the following line to the .csproj file in order for it to work.
<_FunctionsSkipCleanOutput>true</_FunctionsSkipCleanOutput>

I don't know why I get the error, and I can't seem to find a solution online.
If it helps, I am using MiniRazor inside a class library that the Function App is depending on.

I hope someone can help.

Could this have any useful information? https://stackoverflow.com/questions/58634755/method-commoncreatearraytypesymbol-does-not-have-an-implementation

Never used function apps, so can't advise from experience
