If you write code to SQL Server then you might be interested in this: at the end of 2017 I wrote a tSQLt tdd training course which has helped over 300 people learn both tSQLt and how to apply TDD practices to their SQL Server T-SQL development, you can join the course at https://courses.agilesql.club. The course is free if you are happy to wait 10 weeks to complete it, with 1 lesson being made available per week - if you are in more of a hurry or you would like to help support the project you can purchase the course which makes it instantly available to you.

Download SSMS, SSDT or SSDT-BI

It is a constant source of frustration for some people that it is hard to download SSDT or SSDT-BI or you download the wrong thing.

This is an example of some frustration: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/c82354d0-2f88-4…

Anyway, this is now sorted as there is a single page to download SSMS or SSDT:
