People often post questions in the language specific forums when they are not language specific at all. Those forums are for language syntax issues, and language syntax issues only. Therefore, the thread gets moved to its appropriate location and the title is usually altered to reflect the poster's preferred language for replies.
However, not everybody knows the syntax of every language so sometimes an answer might be given in another language. Since we're dealing with the .NET framework here, the method will be the same only using different language syntax. An answer in the wrong language is better than no answer at all.
