Why is package restore failing when I upgrade to ASP.NET Core 1.0.1?

I am attempting to install ASP.NET Core 1.0.1 on my windows 7 dev box which already has ASP.NET Core 1.0 working in Visual Studio Community 2015 Update 3.

To accomplish this I installed .NET Core 1.0.1 - VS 2015 Tooling Preview 2 from https://www.microsoft.com/net/core#windows as indicated by https://blogs.msdn.microsoft.com/dotnet/2016/09/13/announcing-september-2016-updates-for-net-core-1-0/

I then updated several version numbers in my existing project.json file from 1.0.0 to 1.0.1 so that my web application would use the new 1.0.1 components.

As expected this triggers a package restore, but unfortunately it fails. I can't figure out why the packages restore is failing. Any help would be greatly appreciated.

enter image description here

Here are the errors from the output window:

Errors in C:\Users\Ron Clabo\Documents\Visual Studio 2015\Projects\wwwGiftOasisResponsive\src\wwwGiftOasisResponsive\wwwGiftOasisResponsive.xproj Unable to resolve 'Microsoft.AspNetCore.Server.IISIntegration (>= 1.0.1)' for '.NETFramework,Version=v4.5.2'.

My understanding is that the upgrade from ASP.NET Core 1.0 to 1.0.1 is suppose to be pretty easy so I must be missing something simple but after hours of looking I could really use some advice.

Not every package got version bumped to 1.0.1. There is no 1.0.1 version of IIS Integration on nuget. That component should be left at 1.0.0 in your project.json.

You didn't read the upgrade instructions (and here) correctly.

This is not a global version bump. Only the listed packages were upgraded to 1.0.1. All remaining ASP.NET Core packages stay at 1.0.0, this includes Microsoft.AspNetCore.Server.IISIntegration.

The affected packages are:

  • Microsoft.EntityFrameworkCore
  • Microsoft.AspNetCore.Server.Kestrel
  • Microsoft.AspNetCore.Mvc
  • Microsoft.AspNetCore.Antiforgery
  • Microsoft.AspNetCore.Routing
