Answer 1

You usually have more files inside your project that are not source code related like:

• README.md
• CONTRIBUTING.md
• .gitignore
• LICENSE
• Build scripts
• Docs and tools folders, etc.

And a tons of others files that depend on your configuration. So, if you have a src folder, you don't need to mix your source code files with those.

Answer 2

because you may have your code in src folder (class libraries, etc), test in your test folder, documentation in a documetation folder

in global.json you specify which folders does roslyn pick for compiling.
