Unable to install EF Core tools 3.0.0 in .net Core 3.0

[geedsen]

Trying to create the initial migration
dotnet ef migrations add initial --startup-project ..\CojacDB\CojacDB.csproj

results in the following error:

The EF Core tools version '2.1.4-rtm-31024' is older than that of the runtime '3.0.0'. Update the tools for the latest features and bug fixes.
Unable to create an object of type 'CojacJobContext'. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728

running dotnet ef --version shows:

Entity Framework Core .NET Command-line Tools
2.1.4-rtm-31024

doing an install of the 3.0.0 tools:

But the problem remains, the exact error occurs on the migration. and the dotnet ef --version still shows the 2.1.4-rtm-31024

Tried this: dotnet tool install --global dotnet-ef
But no difference

[roji]

Can you please run dotnet tool list --global and post the results?

Not sure if this helps (it did not for me :)

[geedsen]

but this did work:
dotnet tool uninstall --global dotnet-ef
dotnet tool install --global dotnet-ef --version 3.0.0 --interactive

Had to do the uninstall first else it would tell me it was already installed.
