Description

The Dapper.Contrib does not use the ITypeMap instances set for mapping database table column names to POCO property names. Generated SQL statements therefore are wrong when using a POCO with property names not identical to database columns.

Research direction

Start by tracing Dapper.Contrib's generated SQL and how SqlMapper.TypeMaps are currently handled. Done means POCOs with property names that differ from database columns produce correct SQL using their configured ITypeMap instances; add or update coverage for that mapping case.
