Answer 1

I found it, I followed below steps and everything worked fine:

1. first of all, you should edit the paths in project. assets file to become refers to a new project path.

2. Open Power Shell for the same directory that .sln file exist then run below command

   PS E:\WorkSpace\VMTEST\5.5.0\aspnet-core\src\VMTEST.Web.Core\obj>dotnet restore VMTEST.sln
   

   (if won't work, run the command again)

3. Ensure that you have cleared the Nuget caches.

4. clean your project.

5. Build your project.

6. close the VS and reopen it again.

In my case the above steps fix the problem (both problem Package console and restore packages problem).
