.NET 4.5 new Uri unescaping double dot when there's inverted question mark about twitterizer

[meebey]

Not sure if I fully understand the issue. You say the Twitter request becomes a http:// instead of a https:// request when the Twitter message contains an inverted question mark and thus fails with "Could not authenticate you"?

Nope, the problem is that is sending at the querystring parameter "status" "http:". I mean, is sending a double dot without encoding it and if you send it, Twitter answers with the error message "Could not authenticate you".

Ah, so everything is encoded in the status query string except the colon after the http. I think this can easily be workaround by replacing the http: with http%3A. To me this sounds like a bug in the URI class of .NET 4.5 then, but it could also be valid and the Twitter server violates the HTTP specification. Who is wrong makes no difference though as we can't fix either of them and thus need to workaround it in Twitterizer :-)

Yes, it's a bug in the uri class of .net 4.5. I was asking if somebody knows any workoaround for it, because I have tried soooomany things but nothing works :(
