You need to specify the context name. You are only specifying the Migration Name.

Hi,

You need to port Entity Framework 6 to Entity Framework Core, here is the guide https://docs.microsoft.com/en-us/ef/efcore-and-ef6/porting/.

After this porting you will be able to use Entity Framework Core CLI only to run all the migrations.
