c# – NuGet Errors in Visual Studio 2022 After Changing Project Icon and Reinstalling .NET and Visual Studio

I am encountering a persistent issue with NuGet package resolution in Visual Studio 2022 (Version 17.11.4) that started after I changed the project icon in my .NET MAUI solution. Now I am getting multiple errors like the following:

Unable to resolve 'Microsoft.IO.RecyclableMemoryStream (>= 3.0.1)' for 'net8.0-windows10.0.19041'. PackageSourceMapping is enabled, the following source(s) were not considered: C:\Program Files\dotnet\library-packs, Microsoft Visual Studio Offline Packages, nuget.org.

What I have tried so far:

1. Resetting to Last Working Commit:

   • I reset the project to the last commit where everything was working, but the issue persists.

2. Reinstalling Visual Studio and .NET SDKs:

   • I completely uninstalled and reinstalled both Visual Studio and the .NET SDK.

3. Clearing NuGet Cache and Reinstalling Packages:

   • I cleared the NuGet cache using nuget locals all -clear.
   • Reinstalled all NuGet packages with the -Reinstall option.

4. Creating a New Solution:

   • I tried creating a new solution from scratch, but the same errors occur.

5. Verifying Product Versions:

   • I have verified that all the installed products (SDKs, runtimes, etc.) are up-to-date.

My Environment:

• Visual Studio Version: 17.11.4
• .NET SDK Version: 8.0.100
• Operating System: Windows 10

I am attaching screenshots showing all the errors and the versions of the installed components.

Error Details:

• NU1100 errors appear for various packages, including Microsoft.IO.RecyclableMemoryStream, Microsoft.Maui.Controls, etc.
• It seems like PackageSourceMapping is not correctly considering the configured sources, even though nuget.org and the default Visual Studio package sources are enabled.

Request:

I am looking for suggestions on how to resolve this issue. It seems to be related to NuGet and package source mapping, but none of the usual fixes (cache clearing, reinstalling, etc.) have worked. Any insights or troubleshooting steps would be greatly appreciated.

Thank you in advance!
