Command dotnet ef not found

by

I’m following the docs in order to create an initial migration. When I execute dotnet, I get the help section, meaning that the PATH works properly.

Then I try to execute the command below from the docs in console window:

dotnet ef migrations add InitialCreate

I get the following error:

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.

  • I excluded the first item since I copied the command.

  • I excluded the second item because the package Microsoft.EntityFrameworkCore.SqlServer is installed.

  • I excluded the third item because I get the help section when invoking dotnet.

I’m googling the issue but since the version is new, there’s not much to go on and/or it’s drowning in similar issues from earlier versions.

I tried to forcibly install Microsoft.EntityFrameworkCore just in case it needs to be explicitly added. I ran into the error message telling me that the latest version to pick from is 2.2.6 and a downgrade is a no-go. I’m not sure how to install the version compatible with the SQL-package I have on my system already (and even less certain if that’s right approach to kill this issue).

Detected package downgrade: Microsoft.EntityFrameworkCore from 3.0.0-preview6.19304.10 to 2.2.6. Reference the package directly from the project to select a different version.
Web ->
Microsoft.EntityFrameworkCore.SqlServer 3.0.0-preview6.19304.10 ->
Microsoft.EntityFrameworkCore.Relational 3.0.0-preview6.19304.10 ->
Microsoft.EntityFrameworkCore (>= 3.0.0-preview6.19304.10)
Web -> Microsoft.EntityFrameworkCore (>= 2.2.6)
