Answer 1

.NET doesn't support RegEX recursion but you can check this project to use PCRE in .NET

According to the documentation, (?R) is not a valid construct in .NET regular expressions, nor is there any mention on that page of "recursive" or "recursion" so apparently this is not supported in .NET.
