I want to retrieve replies from a Tweet with LinqToTwitter api but i can`t.
I found this but it is already removed.
Some help?
The Twitter API v1.0 introduced a related_results endpoint, but it didn't last long. Except for an initial blog on new API's at that time, it was undocumented. The answer, by Hassan Magdy, to the question you're linking to is accurate as well as it's follow-up comment.
LINQ to Twitter supports what the Twitter API offers. If the Twitter API doesn't support it, neither does LINQ to Twitter. In theory you might approach this task by looking at the user's home timeline to find tweets that reply to a given tweet. However, you would encounter limitations through rate limits, the need to be authorized as the original tweeter, and miss parts of a conversation from people who are not friends or followers of the original tweeter. This would require a significant amount of resources and complex code and still not be 100% accurate.
