When you pass a C# string through an anonymous object, Dapper maps it to nvarchar(4000). That’s the default mapping for System.String in ADO.NET — and honestly, it makes sense from a “safe default” perspective.

This is called CONVERT_IMPLICIT, and it means SQL Server can’t use your index. Full scan. Every time.
