I don’t know a lot about Collation – I know how to set it in SQL Server, I know it’s important, it know chaos can ensure if your not careful for example if you set it to CS rather then CI*, so my general tack is to leave it as default and hope it leaves me alone.
Today however, this happened
Turns out in the VS SSDT package, I have forgotten to set one of the databases collation in project settings to Latin1_General_CI_AS to match the default on SQL Server (rather then the VS SSDT default)
CI – case insensitive – recommended
CS – case sensitive – avoid
