问题
I have 2 existing database diagram in local server in SQL Server 2018, SSMS 18.1 While opening it, the application becomes "Not Responding" then crashes without any error. It was working fine for the last 7 days.
回答1:
By mean 18, if you have SSMS version 18.0 installed then Database Diagrams were deprecated and removed from 18.0 version, and added back into SSMS version 18.1.
Source: Deprecated and removed features in 18.0:
check out Deprecated and removed features in 18.0 in above Release notes for SQL Server Management Studio (SSMS).
