Description

Hi Team,

Using Dapper.Contrib , attribute [Key] is defined for string variable(Here we are intending to use GUID as primary key for your database table).
Insert operation is failed, by throwing error "Column can not be null", but eventually GUI is passed in the variable.

Thanks
Varanasi

Research direction

Start by reproducing the reported Dapper.Contrib insert with a string [Key] containing a GUID and a varchar primary key. Inspect the insert handling for identity keys and verify the expected database behavior; done means the non-null GUID is inserted successfully rather than producing a "Column can not be null" error.
