I'm currently developing a solution using the DeveloperForce tooling for .NET.
In Salesforce, I have created a custom object CustomObject which has the API name CustomObject__c.
When using the same account to get the list of sobjects from the REST API, the custom object is not returned in this list. When using the ForceClient in the .NET library to add a record of this object type, the response returned is "The requested resource does not exist."
What else do I need to do to create custom objects using the REST API?
