I must say that I have experienced random VALUE ERROR of .NET namespace being called that was defined with ⎕USING while multithreading. It was looking like ⎕USING had lost some definition(s) all of a sudden during the callback on another thread. I am glad to see that the original question on this thread resulted in this discussion and possibly will fix this behavior.

I am making one big ⎕USING that is used for the whole workspace and I am not localizing ⎕USING. It would be appreciated to have the recommended way of setting ⎕USING on a large workspace using multithreading from Dyalog after the conclusion of their research on this behavior. Thanks in advance for that.

Good news at the end of the week: fixes have been committed for versions 17.1 and 18.0. I don't yet know when the next patch will go out, but a fix for this problem (our problem ref 17877) will be in it.

Have a good week end!
