While installing the package Microsoft.EntityFrameworkCore.SqlServer (v.7.0.10) using nuget package manager in visual studio, i got an error. Below is the error i got: Error NU5000 An error occurred while retrieving package metadata for 'Microsoft.NETCore.Platforms.1.1.0' from source 'C:\Program Files\dotnet\sdk\NuGetFallbackFolder'.

i don't got any error when installing Microsoft.EntityFrameworkCore.SqlServer(6.0.21) (last version before 7.0); But i got the error i mentioned above in all versions starting from 7.0.

In my PC there is Microsoft.NETCore.Platforms.1.1.0 folder in NuGetFallbackFolder and all packages are available in this folder.

Please share the app type on your side.

And you can try to clean the nuget cahce and change the package source in this situation:

After that, close VS, remove the .vs folder in the solution folder, and then reopen VS:

  • Did not fix it for me unfortunately. I am using visual studio 2022 v.17.7 and the application I am getting this error is Asp.Net core MVC. – almira can Aug 20 '23 at 13:22
  • @almiracan What is the nuget source you are using, is it nuget gallery api? If not, try to use it and check whether the issue exists. :) – Bowman Zhu-MSFT Aug 28 '23 at 08:18
