Upgrade from .net core 1.0 to 2.0 preview 2 warning #2108

Closed huytnd closed 6 years ago

huytnd commented 7 years ago

Today, I upgraded my asp.net core project from 1.0.4 to 2.0 (preview 2). The project was rebuilt successfully but got this warning message: Code: CS1685 Description: The predefined type 'MarshalByRefObject' is defined in multiple assemblies in the global alias; using definition from 'System.Runtime, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' How to get rid of this one?

natemcmaster commented 7 years ago

Not enough details. Can you share a csproj file? It is most likely that you have a package reference that should be removed now that you have upgraded.

Here is the csproj file.

@huytnd there doesn't appear to be anything wrong with your packages. Do you have a type named MarshalByRefObject in your project? This type was added in .NET Core 2.0.

@natemcmaster No, I didn't use, or install this anywhere in my solution, I just upgraded all my packages from 1.0.4 to 2.0 preview2.
