Connect to Salesforce partners WebServices (WSDL) Using Visual Studio 2010/2012/2013 & C#. This is complex WCF example. look for the “DOT.NET 2.0 Style” for easier way.

Step 1:

Logon to Salesforce and download the Partners WSDL and save it to your HD. You can get it from “Setup—>Develop—>API”. Make sure to click “save link as”. open the link and then save it will result corrupted WSDL file.

Step 2:

Add reference to the new WSDL inside your project in Visual Studio using “Add new service reference”.

Step 3:

Write the actual code to query the salesforce using C# and WCF.

Code Snippet
  1. // This client instance will b e use to login and get valid password.
  2. SF.SoapClient loginClient = new SF.SoapClient();
  3.  
  4. SF.LoginScopeHeader header = new SF.LoginScopeHeader(); // not needed in this demo.
  5. SF.CallOptions options = new SF.CallOptions(); // not needed in this demo.
  6.  
  7. // User this URL for production. you can change the API version id needed.
  8. loginClient.Endpoint.Address = new System.ServiceModel.EndpointAddress("https://login.salesforce.com/services/Soap/u/29.0"); // Production
  9. // Use this URL for sandbox.
  10. //client.Endpoint.Address = new System.ServiceModel.EndpointAddress("https://test.salesforce.com/services/Soap/u/29.0"); // Sandbox
  11.  
  12. // Login details - add the token string at the end of the password
  13. SF.LoginResult response = loginClient.login(header, options, "myemail", "mypasswordmytoken");
  14.  
  15. // The object will hold the session id and required for all future communication with salesforce.
  16. SF.SessionHeader sessionHeader = new SF.SessionHeader();
  17. sessionHeader.sessionId = response.sessionId;
  18.  
  19. // Now, after we loged in and have session id - we can start new client and use it to query the salesforce
  20. SF.SoapClient executionClient = new SF.SoapClient();
  21.  
  22. // Here we give our execution client the urk we got from the login call.
  23. executionClient.Endpoint.Address = new System.ServiceModel.EndpointAddress(response.serverUrl);
  24.  
  25. // object to hold our query result
  26. SF.QueryResult result = new SF.QueryResult();
  27.  
  28. // Finaly we can query the salesforce. the result will be in the "QueryResult" object.
  29. SF.LimitInfo[] info = executionClient.queryAll(sessionHeader, options, new SF.QueryOptions(), "select id from account", out result);

    I noticed that ranking your site may be difficult... I had to hire an SEO company to make sure my site stayed at number one. However, it was expensive! It was a constant monthly fee and my company/website was not big enough to afford them. I checked around for a DIY SEO program and <A href="4cfab7xr2fwr21b459giqhvh56.hop.clickbank.net/;>found this one</A>. It worked out well because I knew very little about SEO and I only knew have to manage my website. Anyway just thought I'd share some info with everyone. Good luck and don't give up!!!
