FileLoadException for System.Runtime.InteropServices.RuntimeInformation on old-style .csproj test projects

[poke]

Hey, I’m currently migrating my projects to .NET Core 2.0 and as part of this, I’ve updated the Microsoft.Extensions.Logging.Console dependency on some test projects to 2.0.

When I run tests that attempt to create a console logger, I get the following error:

Message: System.IO.FileLoadException : Could not load file or assembly 'System.Runtime.InteropServices.RuntimeInformation, Version=0.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

I assume this is related to the change introduced with #440 that got rid of the PlatformAbstractions dependency. It also works fine for me in new-style .csproj projects (including test projects) but it just fails with old-style test projects. For some odd reason, the same code within a console application runs fine, even on old-style projects.

My test is literally just the following:

[Fact]
public void TestConsoleLogger()
{
    new LoggerFactory().AddConsole().CreateLogger("Test");
}

Is there anything I can do to avoid this problem other than upgrading to the newer .csproj format? I’ve also tried referencing various different kinds of InteropServices in the project but I couldn’t get it to work.

I’ve prepared a minimum test project that reproduces the problem over here.

Just now, @dasMulli suggested on chat to add the following to the .csproj to turn on binding redirects:

<PropertyGroup>
    <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
    <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
</PropertyGroup>

This ended up fixing my issue, so I’m going to close this.

Overall, this seems to be a general limitation with the old-style projects. The general problematic is also being discussed on dotnet/msbuild#2481.

thanks @poke this worked for me was going crazy. In fact i also removed any in the app.config to get this working
