Edit and Continue applies to C/C++ programs only.
Edit and Continue does not regenerate IDL files; therefore, changes to IDL attributes will not be reflected while you are debugging. To see the result of changes to IDL attributes, you must stop debugging and rebuild your application. Edit and Continue does not generate an error or warning if IDL attributes have changed. For more information, see IDL Attributes.
For information on the limitations of Edit and Continue with Visual Basic and Visual C#, see Edit and Continue with Visual C# and Visual Basic.
