Mvc: Microsoft.AspNetCore.Mvc 1.0.0 does not support framework .NETCoreApp,Version=v1.0.

[NVentimiglia]

When I do a _dotnet build_ I get the following error.

The dependency Microsoft.AspNetCore.Mvc 1.0.0 does not support framework .NETCoreApp,Version=v1.0.

• Project is a minimal MVC site with EF, SQLITE, and a Websocket
• This works fine on windows
• I am running on a mac
• I have updated to the latest dotnet release
• 'new' projects restore, build, and run fine

Full project can be found.

What version of dotnet do you have (Run dotnet --version)? My guess is you either have an RC2 or preview1 build of dotnet.

@pranavkm thanks for the quick reply !

1.0.0-preview1-002702

This looks wrong. I just downloaded and installed dotnet-dev-osx-x64.1.0.0-preview2-003121.

My guess is I am still working with outdated bits, is there an official guide for uninstalling and reinstalling ?

https://www.microsoft.com/net/core#macos should have instructions on how to go about updating. I think it should take care of updating old bits if they're already installed.

@pranavkm

Yes, Ive been using that link as my download source. There are no uninstall instructions for preview 1. Installing preview 2 on-top does not work.

It does but you need to change the following.

@davidfowl Thanks so much, I didn't even think to look in that file.
