DynamicParameters Dapper question

[Derek Beattie]

Probably a silly question:

When I use Dapper alone in a console app, .NET 4.0 I'm able to use optional parameters for .Add.

p.Add("@facility_id", 26);

When I try and do this with ServiceStack.Data referenced I can't use optional parameters.  Any idea why?

#if CSHARP30

            string name, object value, DbType? dbType, ParameterDirection? direction, int? size

#else

string name, object value = null, DbType? dbType = null, ParameterDirection? direction = null, int? size = null

#endif

Basically ServiceStack binaries are compiled in and can run on .NET 3, so we don't use any .NET 4.0 features.

These are dapper's #defines (i.e. in the original Dapper src) that we ported along with the MiniProfiler port.

If you you want the .NET 4.0 version of Dapper you can add a reference to it on NuGet - Dapper in ServiceStack is purposely put in its own namespace so you can run both side-by-side.

Cjeers.
