Compile Error - CF 3.5 C# Application using Ultralte

[Jerry]

Version: SQL Anywhere v11.0.1 build 2376
Compact Framework project targeting CF 3.5

Good afternoon,

I am trying to compile a CF 3.5 project with references that uses the
Ultralite.NET component
during the build and error occurs indicating that System.Data is not
refenced.

It seems that ULConnection requires a call to System.Data

Error 3 The type 'System.Data.Common.DbConnection' is defined in an
assembly that is not referenced. You must add a reference to assembly
'System.Data, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089'. C:\Workspaces\PFS-SOURCE-QA
\PFSSoftware\Smart Device Projects\PFS.Mobile.Client\PFS.Mobile.Client
\clsDBMgr.cs 33 21 PFS.Mobile.Client

Can you advise on how to resolve this ?

Thanks
