Can you create your own MDAs for your own class library/runtime?

Yup they are really cool. You guess it I want to add my own. How could I deploy them? Or do I have to sign a NDA with MS?

Unfortunately, you can't create your own MDAs. The current ones are very intimate with the CLR.
We hope to extend it to be a more general mechanism in a future release.

Any ideas on how to GET RID of the MDA? The registry tweaks on MSDN2 don't help a bit, there are no problems running the executables, etc, but i can't get rid of the MDA messages in the IDE.

This is the MDA error i get:

InvalidVariant was detected
Message: An invalid VARIANT was detected during a conversion from an
unmanaged VARIANT to a managed object. Passing invalid VARIANTs to the
CLR can cause unexpected exceptions, corruption or data loss.

There is no option to get rid of though.

According to http://msdn2.microsoft.com/en-us/library/d21c150d.aspx you only have to set MDA=0 in your registry (which i did), i also tried the COMPLUS_MDA=0, both of them had no effect.

Is there a way (maybe a config file or something) that kills all MDA messages for the current project?

Thanks in Advance,

Nick Kusters.

The env var is the easiest way to disable MDAs.
Are you setting COMPLUS_MDA in a way that ensures that the debuggee will inherit that environment var?
Are you launching your debuggee from VS, or attaching to it under VS?
