Scaffold generator generating incorrect attributes for composite FK associations and MSSQL schema-bound functions
See original GitHub issueDescribe your issue
A large number of tests started failing when we attempted to migrate our project from the old T4 template system to the new scaffold generator. Investigation of the cause revealed two errors in the attributes being generated by the scaffold generator:
- Associations generated from <var>n</var>-component composite foreign key constraints join on the first component <var>n</var> times (redundantly) and the other components never—furthermore, all components of
OtherKeyother than the first get set to the same name (samenameofexpression, even) as the corresponding components ofThisKey, even when the names do not correspond between the tables. In other words, all components of bothThisKeyandOtherKeyapart from the first seem to be clobbered by duplicates of the first component ofThisKey. - We have a schema-bound scalar function which we use from LINQ expressions. SQL Server appears to require it to be referenced with an explicit schema prefix (
dbo.), which the scaffold was not including (unlike the old T4 system). Furthermore, the scaffold attribute was wrapping the name in[], resulting in[…](…)syntax in the generated SQL, which was causing a syntax error on the SQL Server side.

Will be fixed next release. Currently we are busy with other stuff, so PR is welcome
@alexmehlhorn. We are not able to reproduce it and I really don’t see from generator code how it could generate function name without escaping. Check that you have proper version instaled
dotnet tool list -gand if it’s 5.2.0 - create new issue with function declaration script (no body needed, only signature) and your scaffold configuration
