Looking for library for Instant Messaging, like libpurple, but written in C#

Question

I'm looking for an Instant Messaging library that at minimum supports YM, MSN protocol - preferably free but if it's worth to pay, why not.

Answer 1

msnp-sharp is the open source protocol written in c# for MSN. You can get it from http://code.google.com/p/msnp-sharp/ . Its very active.

But i don have any experience with yahoo IM protocol. This link showed up in google search YM Trainer. And Just give a try http://www.ycoderscookbook.com/, incase you are not aware of.

Answer 2

First of all, have you had a look at libpurple-sharp which are .NET bindings for libpurple. Even if the project hasn't released a package, there is a lot of code there already and perhaps it is enough for your application.

I think that the only way that you will achieve support for as many protocols as libpurple is to either use libpurple or port it to .NET.

Answer 3

I've never heard of a multi-protocol IM library for .NET... there are separate implementations for almost all protocols, however. If you really need that, I suggest you create your own library ;).

I can see 2 main options for doing that :

• Create a .NET wrapper for libpurple
• Use the existing separate protocol implementations, extract an abstraction level that fits all of them, and put them all together.

I think the first approach is the best, because the abstraction level probably already exists in libpurple. Whichever you choose, it's going to be a lot of work anyway...
