This issue is occurring because we don t have Entity Framework installed  Please install Entity Framework using the below command   Install-Package EntityFramework -IncludePrerelease   Once installed  choose the project in the package manger console default project drop down   Make sure at least one class in your project inherits from data context  otherwise use the below class   public class MyDbContext   DbContext               public MyDbContext                               If we don t do this we will get another error   No context type was found in the assembly  After completing these things you can run  enable-migrations

I just had the same problem in asp net core VS2019  This solved it   Install-Package Microsoft EntityFrameworkCoreInstall-Package Install-Package Microsoft EntityFrameworkCore Tools   Don t forget to set default project in Package Manager Console to your database project in case it differs   While executing the migrations the default project also seems to play a role  At a later step it helped to install  this to my main startup project  not the EF database project    Install-Package Microsoft EntityFrameworkCore Design
