Unable to uninstall lower SDK patches

[Strong-IT-IBK]

I need to remove all older .NET Core SDK patches. Currently, I have the following SDKs installed dotnet-core-uninstall list --sdk .NET Core SDKs: 5.0.403 x64 [Used by Visual Studio. Specify individually or use --force to remove] 5.0.303 x64 3.1.415 x64 3.1.120 x64

When launching the command dotnet-core-uninstall dry-run --all-lower-patches --sdk nothing is displayed. The expected output should be: *** DRY RUN OUTPUT Specified versions: Microsoft .NET SDK 5.0.303 (x64) Microsoft .NET Core SDK 3.1.120 (x64) *** END DRY RUN OUTPUT

However, when launching the command dotnet-core-uninstall dry-run --all --sdk all SDK versions are listed in the output. *** DRY RUN OUTPUT Specified versions: Microsoft .NET SDK 5.0.303 (x64) Microsoft .NET Core SDK 3.1.415 (x64) Microsoft .NET Core SDK 3.1.120 (x64) *** END DRY RUN OUTPUT

When launching the command dotnet-core-uninstall dry-run --all-lower-patches --aspnet-runtime nothing is displayed. The expected output should be...

@Strong-IT-IBK I believe this is the expected behavior, can you please explain why you believe that should be the output?

Since you're using the --aspnet-runtime switch the tool is only going to display aspnet runtimes, so it should be expected that no SDKs show up in the output.

@sfoslund I am sorry. I unintentionally specified --aspnet-runtime instead of --sdk. I fixed the command lines in my first edit. The actual command I launched is: dotnet-core-uninstall dry-run --all-lower-patches --sdk. However, nothing is displayed in the output even if lower patch versions of SDK are present on the system (see output above).

I am seeing the same thing.

From my understanding the following output indicates that the following SDK's can be uninstalled when using --all-lower-patches:

• 7.0.308 x64
• 7.0.202 x64
• 7.0.110 x64

As they are superseded by 7.0.404 (higher patch version AND the same architecture)

C:\Temp>dotnet-core-uninstall list  --sdk

This tool cannot uninstall versions of the runtime or SDK that are 
    - SDKs installed using Visual Studio 2019 Update 3 or later.
    - SDKs and runtimes installed via zip/scripts.
    - Runtimes installed with SDKs (these should be removed by removing that SDK).
The versions that can be uninstalled with this tool are:
