If we want to do the basic operations like Create, Update, Delete and View records from Salesforce in .NET Console Application, it can be achieved by using REST API and DeveloperForce.Force in Visual Studio.  Below are the steps used to implement the above scenario:


If we want to access the Salesforce Lead object from a .NET Application, you must first install the Develperforce.force(REST API) in NuGet Packages.

Step 5: 

Below is the code/logic that covers all the functionalities explained in this article.
