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
