System information

Godot v4.5.1.stable.mono - Windows 11 (build 26100) - Multi-window, 3 monitors - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 4090 (NVIDIA; 32.0.15.8180) - 13th Gen Intel(R) Core(TM) i7-13700K (24 threads) - 63.77 GiB memory

Issue description

Godot will include .cs files from directories marked with a .gdignore file in the root .csproj/.sln

Steps to reproduce

• Create an empty Godot project
• Add a C# script in the project root
• Add C# scripts to a subdirectory
• Add a .gdignore to that subdirectory
• Delete the .csproj and .sln files in the Godot project root
• Build (in Godot)
• Open the C# project root script
• Observe that C# scripts from the .gdignore'd directory are included in the solution
