.Net Core 1.1.0 NuGet packages fail to install in Visual Studio Mac

Question

I'm playing around with a ASPNet.Core 1.1.0 application in Visual Studio Mac Preview and have problems updating/installing NuGet packages.

If I try to update eg. Microsoft.AspNetCore.Diagnostics from 1.0.0 to 1.1.0 it fails the download and removed the package completely. I then have to download and install the package for 1.0.0 again. Same goes for Microsoft.AspNetCore.Server.Kestrel.

Microsoft.EntityFrameworkCore I'm not able to install in any version. Heres the exception output: https://gist.github.com/anonymous/52ceb28b8d9781835b226bcbe9d04d58

I know everything is right out of the oven, but was wondering if other people have experienced the same issues and know of a workaround/solution.

For everyone else having similar problems, here's a walk-through:

1. First install .NET Core 1.1.0: https://www.microsoft.com/net/core#macos

2. The official .NET Core 1.1.0 installer (as of when this is written) includes the .NET Core SDK 1.0.0 Preview 2.

You will need .NET Core SDK 1.0.0 Preview 3. Download it here: https://github.com/dotnet/core/blob/master/release-notes/preview3-download.md

3. Create a new project in Visual Studio Mac

4. Close the project

5. Open up project/src/myapp/myapp.csproj and change "netcoreapp1.0" to "netcoreapp1.1". Save and close the file.

<TargetFramework>netcoreapp1.1</TargetFramework>

6. Open your solution in Visual Studio Mac and compile it.

Now you will be able to update your NuGet packages to newest versions.

Should you run into problems, do a "dotnet restore" when standing in /project/src/myapp/
