Research direction

Start with the Stack Overflow report linked in the issue and reproduce the exception using MySQL, Dapper 1.50.2, and a model containing a property named Date. Trace the System.Reflection.Emit.DynamicILGenerator.Emit failure and consider the issue resolved when that model maps without the ArgumentNullException while the existing behavior remains intact.
