[Package Issue]: Microsoft.DotNet.SDK.8

Please confirm these before moving forward

• I have searched for my issue and not found a work-in-progress/duplicate/resolved issue.
• I have not been informed if the issue is resolved in a preview version of the winget client.

Category of the issue

Installation issue.

Brief description of your issue

You can't install both the x64 and x86 architecture versions of this package. Once you install one architecture, you get an error that the package is already installed when you attempt to install the other architecture. This is clearly allowed if you go to https://dot.net and download both the x64 & x86 versions of the 8.0.403 versions of the SDK.

Steps to reproduce

On a clean Windows machine run:

winget install Microsoft.DotNet.SDK.8 --architecture x64

That will work. Now run:

winget install Microsoft.DotNet.SDK.8 --architecture x86

Actual behavior

The second install fails with:

Found an existing package already installed. Trying to upgrade the installed package...
No available upgrade found.
No newer package versions are available from the configured sources

Expected behavior

I expect to be able to install BOTH the x64 AND the x86 versions of the .NET 8.0 SDK on my test PC.

No response

Reproduce the issue on Windows with the two winget commands shown: install Microsoft.DotNet.SDK.8 for x64, then x86. Trace how the package is identified across the two architecture requests and verify that the completed change allows both SDK variants to install without treating the second as an upgrade.
