Problem with Migration in ASP .NET Core

Gordana Tasic

Hi,

I want to add first migration in database, but I get error "Method 'get_Info' in type 'Microsoft.EntityFrameworkCore.Infrastructure.Internal.SqlServerOptionsExtension' from assembly 'Microsoft.EntityFrameworkCore.SqlServer, Version=1.1.6.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' does not have an implementation."

Does anyone know how to solve this?
