Nevermind, all this fuss for nothing.

I was able to fire the sproc from my .net app w/o having to do anything
special.

It's all good now, thanks for your help!

OK, this is simple. You define the input argument for description as a
blob, but you passed a string to it. Either redefine the input argument as
a varchar (valid up to 32,565 bytes in length) or pass a blob.

It doesn't matter - the db engine doesn't care. But it does care if it is
expecting a blob and you pass a string.
