I'm not able to get a vanilla NET Core app to with localized stream resources to compile. The app is targeting net core 2.0. I've created a repo with a simple project to repro the error: https://github.com/amrmahdi/dotnetcore-localized-resources

The error that I get is

E:\repro\Resources\AudioFiles.en-US.resx(123,5): error MSB3103: Invalid Resx file. Could not load file or assembly 'System.Runtime.Extensions, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencie s. Reference assemblies should not be loaded for execution.  They can only be loaded in the Reflection-only loader context. (Exception from HRESULT: 0x80131058) Line 123, position 5. [E:\repro\repro.csproj]

The resource files are added using the Visual studio experience.

Copied from original issue: dotnet/sdk#2228

This works if I edit the .resx files manually and replace System.IO.MemoryStream, System.Runtime.Extensions, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a with System.IO.MemoryStream, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089.

Why does Visual studio references the wrong assembly ?

Why does Visual studio references the wrong assembly ?

The reference VS wrote is technically correct, but the code that is reading the resx is assuming that it can do an active load on assemblies that appear in it.

It’ll probably work on .net 4.7.1 since that assembly is in the unification table but that’s a hack. I thought this same problem was hit for UWP and a task was rewritten on s.r.m or LMR. Apparently not this task.
