Fix a coding/API issue

Job Description:

We have an app that interfaces with our CRM system (Salesforce). The app has been written in C#.

Salesforce is undertaking some updates which means the legacy versions 21.0 through 30.0 of the Salesforce Platform API are no longer supported by Salesforce.

We have been told to modify or upgrade our applications to function with the supported APIs in order to prevent any disruption caused by software referencing deprecated versions.

I would like to hear from anyone who can take a look in to updating the API in the code.

Skills:, Salesforce App Development, Software Architecture, C# Programming, PHP
