Description

Hi, I answered this question today
https://stackoverflow.com/questions/55398454/how-to-instanciate-an-object-by-activator-createinstance-an-inserting-it-on-a-ta/55398570#55398570

He used object as generic argument. Which broke dapper. The reason why is becasue you do var type = typeof(T). The correct way would instead be var type = entity.GetType();

Research direction

Start at Insert(TEntity entity) and inspect how the entity type is determined, especially the current typeof(T) usage. Reproduce the case where object is the generic argument and verify that insertion uses the entity's runtime type instead; done means that scenario no longer breaks Dapper.
