attempting to use #Develop for existing c# code enhancement

hello, i have an application written in c# [by a collegue] using MS visualStudio [i don't have MS visualStudio yet...] i need these references [dll's ?] in order to build the application:

-------------------------------------------------------------------------

using System.Web.Security;
using System.Security.Cryptography.X509Certificates;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

using ComponentSpace.SAML2;
using ComponentSpace.SAML2.Assertions;
using ComponentSpace.SAML2.Protocols;
using ComponentSpace.SAML2.Bindings;
using ComponentSpace.SAML2.Profiles.SSOBrowser;
using System.Security.Cryptography.Xml;
using System.Security.Cryptography;

using System.Text;

-------------------------------------------------------------------------

is it possible to "import" them into #Develop 5.1 ?

thanks for listening -
