I was using v1.0 the API for simple HTTPWebRequest tweet query in C# code until now, and it no longer works.
I have been trying to switch over to v1.1 for the past three days and it has been a nightmare.
Specifically, I tested the consumer key/secret and access token/secret I was given at with every .NET code sample(more than a dozen) and it failed to authenticate. Even the application only authentication using the consumer key and consumer secret failed.
So where do I test these keys and token to make sure they are valid?
