Description

I have a simple enum just like this:

public enum Foo
{
  First,
  Second,
  Third
}

When saving in the dabase, the value are stored as the indexed position of the enum value.
Is possible to store an enum property as string in the database?

Research direction

No file or test is named in the issue. Start by tracing Dapper's handling of C# enum properties during database writes, then compare the current indexed storage with the requested string storage; done means enum properties can be persisted as strings without breaking existing mapping behavior.
