Subject: [PATCH] [fix] fix the bug in GenericReferenceWriter where
 _systemTypePattern did not properly escape the '.' in type names. This caused
 issues when compiler-generated anonymous types and functions contained string
 sequences like 'System-Int', incorrectly matching them to 'System.Int',
 resulting in runtime exceptions.
