Nuget Catch 22 after migrating VB project

Question

I am migrating a VB project from VS 2010 to VS 2017 and I am getting the following errors:

Error occurred while restoring NuGet packages: System.ArgumentException: '$(NETStandardImplicitPackageVersion)' is not a valid version string.
**StackTrace**

and

'C:\Users\PathToProject\obj\project.assets.json' not found. Run a NuGet package restore to generate this file.

I can get around the first error by turning off nuget restore as mentioned here but then i can't get past the second error, which requires nuget restore, or some other way to generate project.assets.json

Here is my vbproj file:

Can you make a dummy project with the requisite NuGet packages and copy the generated project.assets.json (with any appropriate path etc. changes) to the real project? — Andrew Morton, May 24 '18 at 18:58
Or, David Kean tantalisingly suggests that a `` property might need to be present towards the end of the thread [another nuget error](https://developercommunity.visualstudio.com/content/problem/159294/another-nuget-error.html). — Andrew Morton, May 24 '18 at 19:08
Wrote an answer based on the wrong project system hint. If it doesn't help, please include the csproj content in the question to be able to reproduce it. — Martin Ullrich, May 25 '18 at 02:22
Note that WinForms projects aren't really supported in the SDK/project-system, I'd be interested in how far you can get it to work. Also, you can remove the VB targets import since the SDK already does that. — Martin Ullrich, May 25 '18 at 18:40
Also, why are you using the web sdk? ( `Microsoft.NET.Sdk.Web` ) since it is not a web application, you should remove the `.Web` — Martin Ullrich, May 25 '18 at 18:40
What you are trying to do is highly experimental at best.. if you want stable tooling you should use a normal migration by opening the old project file in VS 2017 instead. — Martin Ullrich, May 25 '18 at 18:42

Remove the csproj from the solution and add it again. Make sure you have a recent version of VS 2017 (at the time of writing 15.7.2).

This can happen if you migrate to an sdk-style project (<Project Sdk="Microsoft.NET.Sdk">) which is loaded using the classic csproj project system instead of the new project system specifically designed for this type of project.

The GUIDs in the solution as well as the ocurrance of a <TargetFramework> property determine which project system is used to load the csproj.
