Application Names and Database Queries

Tom Zika does not like those missing application names:

Whenever I’m trying to debug a problem using sp_whoisactive or Extended Events (XE) and I see either Core Microsoft SqlClient Data Provider or .Net SqlClient Data Provider, my blood begins to boil.

It means I’ll probably spend hours asking around to try and find the owner. Sometimes knowing the host_name helps, but there can be a multi-purpose host that runs many applications – which one is having the problem?

How do you set the name? Read the post to find out.
