Description

Creating an app domain and then having it perform a callback that requires the test assembly to be loaded results in a load failure. This used to work in project.json land.

Steps to reproduce

• git clone git@github.com:aspnet/Mvc.git
• cd Mvc
• git fetch
• git checkout nimullen/migration.createdomain
• cd test/Microsoft.AspNetCore.Mvc.Core.Test
• dotnet restore
• dotnet test -f net451 --filter "FullyQualifiedName=Microsoft.AspNetCore.Mvc.Infrastructure.ActionContextAccessorTests.ChangingAppDomainsDoesNotBreak_ActionContextAccessor"

Expected behavior

Test Passes

Actual behavior

Test fails
