C# Authorize.net auto recurring billing

I need? [login to view URL] ARB(Automated Recurring Billing) API. Currently, AIM(Advanced Integration Method) has been already deleveloped in my current ~.aspx & ~.cs So I need CS code to be added for? just ARB api option (Create subscription, update or cancel)? to current source. ## Deliverables I need the code in C# for a project that I am working on. This Website project is built in C# & ASP.NET 3.5 Now my current source page (1 page) can handle regular card payment (AIM) except for ARB. So I want to add Automated Recurring Billing here. When users choose ARB option and submit billing info., it will be processed first month right away and a subscription will be created. When your bid is accepted, I will show you my current source code for you to add ARB option. You don't have to worry about database part. Because after the payment & subscription, I want to add the inserting to database. When the processing is done, users will be re-dirrected them to a thank-you page. I want you to test using your own test account in your testing environent.
