Answer 1

.NET Core 2.1

This bug has been fixed in .NET Core 2.1: https://github.com/dotnet/corefx/issues/23229

.NET Core 2.0

Delete the bin folder in the Web project and rebuild the solution.

Add the following to your project file:

<Target Name="RemoveNetFxForceConflicts" AfterTargets="ResolveAssemblyReferences">
  <ItemGroup>
    <ReferencePath Remove="@(ReferencePath)" Condition="'%(FileName)' == 'netfx.force.conflicts'" />
  </ItemGroup>
</Target>

Answer 2

As @aaron stated, the solution is deleting bin folder.

In details;

• If you are using IIS, restart IIS.
• Close Visual Studio. Delete all BIN & OBJECT folders.
• Update Visual Studio to the latest. 15.4.0
• Making sure ApplicationPoolIdentity's .NET CLR version is set to "No Managed Code".

PS: This issue is not directly related to aspnetboilerplate. It's about corefx...
