Test case has a composite key of (int, datetimeoffset, int). Service methods are generated with the datetimeoffset parameters having a type of string, and a few cases won't compile. For now I've changed my DB data type to varchar(34) to see how that works.
EditEntity.razor.designer.cs Load event:
error CS1503: Argument 2: cannot convert from 'string' to 'System.DateTimeOffset?'
Appears to be incomplete work at present, as the code is wrapped in an empty exception handler (?!), whereas similar calls for other entities are not.
