ASP.NET integration

Yes, but i don't only need validate or dispaly information. I need add it in confluence from the ad-hoc application (writing code).

Yes.

I think you need to expand on this question if you want more detail - "integrate X with Y using technology Z" is quite a vague question. The answer is generally "yes", but there's usually caveats.

Thanks Nic. We are developing an ASP.NET application. En each screen we need to add a control (or something like that) to write something about the entity (e.g. the Client "Lopez S.R.L." pay the Budget number 23343) and that information must be sync with the wiki.
