I'm using the latest R# (2018.3.4) and VS 2017 (15.9.8). Currently i'm working on a solution which uses NHibernate.
I have a performance problem when i step through methods which executes NHibernate LINQ queries. The first processed query hangs for a couple of seconds. But the more often i step over such a query, the longer the debugger hangs. After the third time or so i have to restart the application, because the debugger seems to be in an endless loop.
If i disable the Editor adornments and data tips in the debugger options the problem is gone. If i disable R# debugging is significant faster.
The problem occurs also with Visual Studio 2019 RC (16.0.0 RC1.SVC1) .
