We need to reduce the length of the filename / path or this PR, they are forcing us to use incredibly short path to pull Uno's repo.

@dr1rrb Which file is causing the issue?

@Youssef1313 I would say all the files in the TestOutput folder have very long file path, and in my case I've 3 files that have too long filename. For instance https://github.com/unoplatform/uno/blob/master/src/SourceGenerators/Uno.UI.SourceGenerators.netcore.Tests/XamlCodeGeneratorTests/TestOutput/When_Grid_Uses_New_Assigned_ContentProperty_Syntax/XamlCodeGenerator_Grid_Uses_New_Assigned_ContentProperty_Syntax_9f853e56098ff21d39f15479035509ef.cs is 244 char long (relative to repo root) which breaks on windows as soon as you are checking out the repo in a more than 11 char long path dir (even with long file path enabled).

I'm going to change the name of the tests to reduce the length of the generated filenames.

@dr1rrb I have no idea why it's not working with long path enabled. On my machine, I have the repo at C:\Users\PC\Desktop\ which is more than 11 characters and I didn't see issues.

But it should be okay to rename the tests. I'm even interested to find a way to remove the hash from the file name, but that's another thing.

Jérôme pointed me that there is an option in .gitconfig to enable long filename

[core]
    longpaths = true

Will still change the test name to improve first experience :)
