Missing TabItemHelper.cs file referenced in Source Link – causes debugging issues

[grimmiegramm]

Describe the bug

On iNKORE.UI.WPF 1.28 and iNKORE.UI.WPF.Modern 0.10.0,

While debugging an application that uses the iNKORE.UI.WPF.Modern NuGet package, Visual Studio attempts to locate the source file:

E:\Yoojun Products\iNKORE.UI.WPF.Modern\source\Inkore.UI.WPF.Modern\Controls\Helpers\TabItemHelper.cs

The debugger uses Source Link and tries to access the file at:

https://raw.githubusercontent.com/iNKORE-NET/UI.WPF.Modern/0c069985a218b616994b5193516eae2c73fd896a /source/Inkore.UI.WPF.Modern/Controls/Helpers/TabItemHelper.cs

Commit: 0c069985a218b616994b5193516eae2c73fd896a

However, the request fails with a 404 error because the file does not exist in the repository or is not publicly accessible at that commit.

Impact: This results in:

• NullReferenceException stack traces pointing to source files that cannot be inspected
• Debugger failing to step into or decompile library code
• Degraded debugging experience for users relying on Source Link

Exception thrown at:

Thanks in advance.

Reproduction

1. Create a new WPF application.
2. Install the iNKORE.UI.WPF.Modern NuGet package.
3. Add a TabControl with one or more TabItem elements using the default iNKORE styles.
4. Run the application in Debug mode.
5. When a NullReferenceException is thrown from TabItemHelper.UpdateTabGeometry, open the Call Stack and attempt to navigate to the source file.
6. Visual Studio will attempt to fetch: https://raw.githubusercontent.com/iNKORE-NET/UI.WPF.Modern/0c069985a218b616994b5193516eae2c73fd896a/source/Inkore.UI.WPF.Modern/Controls/Helpers/TabItemHelper.cs

which results in a 404 error.

Expected Behavior: Visual Studio should locate and display the source file for better debugging support.

Actual Behavior: Debugger cannot locate the source file due to missing commit or missing file in public repo, causing Source Link failure.

[NotYoojun]

It doesn't exist because somehow the casing of the path is changed. It should be:

source/iNKORE.UI.WPF.Modern/Controls/Helpers/TabItemHelper.cs

You should be able to view the file at: https://raw.githubusercontent.com/iNKORE-NET/UI.WPF.Modern/0c069985a218b616994b5193516eae2c73fd896a/source/iNKORE.UI.WPF.Modern/Controls/Helpers/TabItemHelper.cs

But somehow iNKORE became Inkore and git is not ignoring cases so 404 happened. 'Inkore' was the form that we used years ago before we changed everything to 'iNKORE', but I don't know who is ignoring the changes and still using the old crappy one.

I tried to re-clone the repository, but that didn't work.
