33 // Many of the methods of Microsoft.VisualBasic.dll take
34 // default argument values. The whole of Mono's
35 // Microsoft.VisualBasic.dll is implemented in C# and C#

40 // This internal attribute:
41 // Microsoft.VisualBasic.CompilerServices.__DefaultArgumentValueAttribute
42 // is used to associate a default argument value with a method
45 // The compiled Microsoft.VisualBasic.dll assembly is then
46 // post-processed through a "disassemble-fixup-assemble cycle"
47 // which strips off the "__DefaultArgumentValue" custom
48 // attribute from the method parameter and replaces it with
49 // the suitable CIL parameter flags and constants.
