How to use Salesforce Marketing Cloud API to connect with my SQL server?

[atonalwilson]

I need to use C# to do an HTTP POST request to acquire an access token, but I have no idea how to do it. Salesforce Marketing Cloud is a customer relationship management (CRM) platform for marketers that allows them to create and manage marketing relationships and campaigns with customers. I need to run this sample code in C#:

POST https://auth.exacttargetapis.com/v1/requestToken
Content-Type: application/json

{
"clientId": "gyjzvytv7ukqtfn3x2qdyfsn",
"clientSecret": "************"
}

I am using SSIS 2008r2, I want to write c# code to make an API call to the exact Target API to connect to the SQL server database. Because I want to pull data from the SQL server to the marketing cloud. I didn't find any article about using SSIS to connect Marketing cloud.....the salesforce marketing cloud rest API or FuelSDK looks like it only supports .net 4 or higher.
