  • Hi Dan

    Welcome to the MSDN forum.

    This error usually shown the package cannot be found on any sources.

    The solution 1: Examine the project's dependencies in Visual Studio to be sure you're using the correct package identifier and version number. Also check that the NuGet configuration identifies the package sources you are expected to be using. 

    The solution 2: In Visual Studio go to Tools -> NuGet Package Manager -> Package Manager Settings. Here select the Package Sources tab in the tree on the left. You should see the following:

    If the nuget.org package source is missing, add it manually by clicking the green plus button in the top right corner and setting:

    • Name: nuget.org
    • Source: https://api.nuget.org/v3/index.json

    Sincerely
