public interface IDataEnvironment
{
    // Methods
    DesignerDataConnection BuildConnection(IWin32Window owner, DesignerDataConnection initialConnection);
    string BuildQuery(IWin32Window owner, DesignerDataConnection connection, QueryBuilderMode mode, string initialQueryText);
    DesignerDataConnection ConfigureConnection(IWin32Window owner, DesignerDataConnection connection, string name);
    CodeExpression GetCodeExpression(DesignerDataConnection connection);
    IDesignerDataSchema GetConnectionSchema(DesignerDataConnection connection);
    DbConnection GetDesignTimeConnection(DesignerDataConnection connection);
    // Properties
    ICollection Connections { get; }
}

该服务的使用方法：

            IDataEnvironment service = (IDataEnvironment)GetService(typeof(IDataEnvironment));
            if (service != null)
            {
                DesignerDataConnection connection = service.BuildConnection(null, null);
            }
