About a month ago, I was testing out some ideas in Radzen and connected to our production SQL Server. The 'Infer Schema' worked fine, even if it did take several minutes to respond.
Not having much time to test since, I upgraded to the most recent version a couple of days ago and now, trying the same process, the infer schema process times-out after 30 seconds.
The database has around 550 tables and 530 views.
All SQL Server connections timeouts are set to 10 minutes including remote query timeout's.
