I wish did fix the issue. Well I still don't see where you work with GameInfo - your description absolutely doesn't correspond with your code. By looking at your code I guess the problem will be in the snippet like this:
code :
foreach (var game in model.Games)
{
    if (!dataModel.Games.Any(e => e.GameId == game.Id))
    {
        DataGame dataGame = new DataGame();
        dataGame.GameId = game.Id;
        dataGame.GameName = game.Name;

        dataModel.Games.Add(dataGame);
    }
}
foreach (var game in model.Games)
{
    if (!dataModel.Games.Any(e => e.GameId == game.Id))
    {
        DataGame dataGame = new DataGame();
        dataGame.GameId = game.Id;
        dataGame.GameName = game.Name;

        context.Games.Attach(dataGame); // Now the context knows that it is not a new entity 
        dataModel.Games.Add(dataGame);
    }
}

Hope this helps No it is not how it works. When you implement interface you must return exactly the type defined in the interface definition. Also there is some discrepancy in generic types you are using in your example - Patient / Client.
You can redefine the interface like:
code :
 IQueryable<Client> ClientsQuery();
 public IQueryable<Client> ClientsQuery()
 {
     return Clients;
 }

code :
Install-Package EntityFramework -Version 6.1.1
<configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

      </context>
    </contexts>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />

fixed the issue. Will look into that further Per Microsoft:
"EF Core does not support the EDMX file format for models. The best option to port these models, is to generate a new code-based model from the database for your application."
