External User-Defined Function

[SMitchell]

Does anyone have any experience creating an External User-Defined function? I'm hoping (not sure if it's possible) to create on in C#, I know it has to use the C calling conventions.

Any thoughts?

If I recall, there are some sample external UDFs provided with the product - dlls and corresponding c code.  It may be worth taking a look at these as a first step.
