Could not add a migration in ef

Question

I am trying to add a migration in a Visual Code in ef using the following syntax:

dotnet ef migrations add A_isVerified

All I get is this:

Could not execute because the specified command or file was not found. Possible reasons for this include: * You misspelled a built-in dotnet command. * You intended to execute a .NET Core program, but dotnet-ef does not exist. * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

What can I do to resolve this?

Answer 1

Remember to add Microsoft.EntityFrameworkCore.Design as a package in your project. See more at https://docs.microsoft.com/en-us/ef/core/miscellaneous/cli/dotnet

Answer 2

dotnet tool install -g dotnet-ef
