Assume that this is always the case and delete the logic of "remove DataTestMethod"

Simplified the logic as requested. The code fix now always replaces [DataTestMethod] with [TestMethod] regardless of whether both attributes exist together. Removed the complex branching logic and the RemoveAttributeAsync method. Fixed in commit 78f5305.

Reverted changes to DataTestMethodAttribute.cs as requested. The implementation now uses a purely analyzer-based approach without modifying the runtime attribute. Fixed in commit 8687172.

Remove this condition. It's always true.

Removed the redundant condition as requested. Since the CodeFixProvider only exports for C#, the language check was always true. Simplified the implementation by moving the logic directly into RegisterCodeFixesAsync and removing the unnecessary method. Fixed in commit 33c71b0.

This always return completed task. Make the return type void instead.

Changed the method to be synchronous and return Document directly instead of Task<Document>. Removed the unused CancellationToken parameter and updated the call site accordingly. Fixed in commit a260b1b.
