How To Remove .NET Runtime And SDK On Mac - IT Nota

Check Installation

Determine which version is installed with the command line.

According to Microsoft documentation, we need to remove the SDKs and runtimes separately:

Pay attention to the difference in installed locations between the Intel Mac vs. Silicon M series chip.

Arm-based mac: /usr/local/share/dotnet/ Intel-based mac: /usr/local/share/dotnet/x64/dotnet/

In this example, I want to remove the .NET 6 RC on an M1 silicon Mac from previous test.

% dotnet --list-runtimes Microsoft.AspNetCore.App 6.0.0-rc.1.21452.15 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App] Microsoft.NETCore.App 6.0.0-rc.1.21451.13 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App] % dotnet --list-sdks 6.0.100-rc.1.21463.6 [/usr/local/share/dotnet/sdk]

Uninstall .NET

From the example above, we’ll remove all instances. All these commands can be entered all at once in the Terminal, it will ask you to enter sudo password just once.

sudo rm -rf /usr/local/share/dotnet/sdk/$version sudo rm -rf /usr/local/share/dotnet/shared/Microsoft.NETCore.App/$version sudo rm -rf /usr/local/dotnet/shared/Microsoft.AspNetCore.All/$version sudo rm -rf /usr/local/share/dotnet/shared/Microsoft.AspNetCore.App/$version sudo rm -rf /usr/local/share/dotnet/host/fxr/$version

That’s it.

You can re-run the dotnet –list-runtimes and dotnet –list-sdks to verify that there’s no longer any .NET installed. You should see something similar to this:

% dotnet --list-runtimes A fatal error occurred. The folder [/usr/local/share/dotnet/host/fxr] does not exist % dotnet --list-sdks A fatal error occurred. The folder [/usr/local/share/dotnet/host/fxr] does not exist

Now you can install the new version for your .NET development.

2. great write up but not helpful because of the following reasons

   Are the sudo commands to be entered all at once on the terminal or one after the other ? How do you confirm if the sdks and runtimes are successfully removed ?

   Maybe you should update this article
