ModelState mate and parameter didn't get deleted in table

[Frederick_Law]

When a assembly mate is deleted, it didn't get deleted in ModelState table.

Sometime even deleted parameter stay in the table.

Hi Frederick,

This sounds like a bug to me. Does it happen persistently? Please share an example that exhibits the behavior. I would like to understand the iMate deletion behavior better.

Many thanks!
