Out of bound of array error while creating Database Diagram SQL Server 2017

Question

I am using SSMS 2017 and my database is SQL Server 2016 Enterprise. An error is being shown while creating a database diagram:

The index is out of bound of array

How to resolve it? Thank you in advance

Answer 1

I figured it out myself by Creating database diagram in SSMS 2016, turns out you can create Database diagrams in their own/same version browsers. Thanks anyways

Like if your SQL SERVER database engine is of 2016 you need to also use SSMS of 2016 to create its database diagram.

Answer 2

As workaround, try starting SSMS as Administrator.
