Cannot install dotnet-ef tool on Windows 11

I'm trying to install the dotnet-ef tool via the dotnet-cli.

The command that I enter: dotnet tool install --global dotnet-ef --version 6.0.4

It gives me the following error:

C:\Users\orbit>dotnet tool install --global dotnet-ef --version 6.0.4
C:\Users\orbit\AppData\Local\Temp\yfvm4duz.fcf\restore.csproj : error NU1211: Project restore must have a single package reference(s).
C:\Users\orbit\AppData\Local\Temp\yfvm4duz.fcf\restore.csproj : error NU1212: Invalid project-package combination for Packaging.Targets 0.1.171. DotnetToolReference project style can only contain references of the DotnetTool type
The tool package could not be restored.
Tool 'dotnet-ef' failed to install. This failure may have been caused by:

* You are attempting to install a preview release and did not use the --version option to specify the version.
* A package by this name was found, but it was not a .NET tool.
* The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
* You mistyped the name of the tool.

Some info using dotnet --info command:

  Microsoft.WindowsDesktop.App 6.0.4 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]

I have an acces to https://api.nuget.org/v3/index.json so it's not the problem with my internet connection.

I tried to delete C:\Program Files\dotnet\sdk-manifests without any result.

Also I tried dotnet tool install -g dotnet-ef --version 6.0.4 --ignore-failed-sources command. The same exception message.

I found that this problem could be not only with the dontet-ef tool, but with every tool, because I tried to install dotnetsay tool and got the same exact error messages.

I solved the same issue by removing

  • the executable dotnet-ef.exe from C:\Users\%USERNAME%\.dotnet\tools
  • the folder dotnet-ef from C:\Users\%USERNAME%\.dotnet\tools\.store\

manually.

After that, I used dotnet tool install --global dotnet-ef --version 6.0.6

Try to uninstall it with this command:

dotnet tool uninstall --global dotnet-ef

then install (without --version) like this:

dotnet tool install --global dotnet-ef

and check the version, if you want to update to newer versions, try this command:

dotnet tool update --global dotnet-ef
