I want to suggest you to add Solution folder in your extension.

You need to do 2 things: hide some folders and files and enable file nesting.
- Hide files. Into
settings.json:
"files.exclude": { ".vscode": true, "*/**/bin": true, "*/**/obj": true, "*.sln": true, }
- File nesting. into your
settings.json:
"explorer.fileNesting.patterns": { "*": "${basename}.*.${extname}" }

all file nesting patterns: https://github.com/antfu/vscode-file-nesting-config
C# commands (C# Toolbox: Options) should be moved into Solution folder:

also it would be better if Solution folder will have Studio Icons.
how to nest all projects into *.sln and how to nest projects into *.csproj I dont know but if you can do it then calling *.sln and *.csproj files should be made by context menu (like in vscode-solution-explorer):
