Dapper Contrib - InsertAsync typeof not correct

[andreatosato]

Hi all,
In my Azure Function custom output binding I have problem with Insert method.
My T entity is an interface, but at runtime I have concrete type.
I change this line of code in my scenario:
https://github.com/StackExchange/Dapper/blob/d19d6012e75feebf24d591ad21b16f13becc95f2/Dapper.Contrib/SqlMapperExtensions.Async.cs#L142
This is my resolution:

var type = entityToInsert.GetType();

Do you think that this is correct fix in all scenario?
Thanks a lot

P.S. my sample is here:
