I am not a socket programmer, but I need to develop a RTSP streaming server in c# .net.
I am developing a blackberry application, but it does not have native video calling support. So to fulfill my requirement, I want to create an intermediate streaming server, that will capture my video data (live bytes) from one BB device, and send it to another BB device. This will be live streaming, just like video calling.
But I have no idea on how to implement it in c# .net. I have tried to google for some code, but didn't get any useful links.
Please suggest if I am not on the right track. I am asking for c# .net as I feel it a bit easier to build for someone newbie like me.
Thanks in advance.
RTSP is going to be a very difficult choice for this. It requires coordinating a TCP control socket and multiple separate channels of UDP data.
You're much better off with any variant of HTTP Video or RTMP or RTMPF. HTTP Video has no single standard--just break up video and send in chunks. Easy. RTMP is used with Flash but can be used separately. There arr sample apps in .NET and Java. RTMPF is also used by Flash but is UDP based instead of TCP and is Peer-to-Peer focused. I think there are also sample implementations available.

I have a requirement to develop a VoIP Server (Viber like App). The client software has to be implemented on Android and the server software has to be implemented on .NET.So ,basically, the setup will consist of a server app running on a PC and a wireless access point allowing the clients (Android phones) to connect to the server.Some of the functions I will need for the server side:
Voice transmission
Instant Messaging.
Can anyone help me to implement such a server in .Net?
How much you want to do and what does the server have to do?
The MOST common approach these days is SIP (which is where "know how to read" comes in - that is a public spec, google, RFC, start going, quite long). The good thing is - SIP does not deal with audio at all on the server ;) See, unless you make a audio playback of some sort, noone wants to talk to the server. When I use my phone system, I talk to SOMEONE; not to the server.
SIP deals with SESSION INITIATION - it is a control protocol. The actual audio etc. streams are done via RTP & RTSP - again public protocols, have fun reading (and seriously, they are complex). Unless you NEED the audio streams on the server (recording etc.) there is NO need for the server even to see them - SIP is perfectly fine setting up sessions between two clients directly. SIP is done by MOST (by far) VOIP today. You may use a predefined library. Otherwise you are in a world of quite a lot of debugging, sorry ;)

we are in the process of determining what would be the best technology to write our signage player . Although we are a C# house with some experience in Java, all the talk has been about Java and Mono. Also the platform we are going to build on would be a linux box.
The player has to be very intelligent and support scheduling, content change triggers by external applications (by web services), time synchronization of content, content show in different portions of the screen, video/live streamed feed etc.
We will also need to create a designer to allow the design team to create webgl content.
There is some OpenGl experience in the company so we could leverage this.
Would this be a good choice?

That would be an excellent choice IF and only IF you have a good grasp on Javascript or your timeline isn't too tight in case you don't dominate Javascript. If going on a linux box, chances are you're better off with a custom build of Firefox or Chromium running your app alone without the browser parts (menus, tabs, etc).
My team here is working with HTML5+Javascript+Canvas/WebGL on the client side almost exclusively now because it is very fast to develop and needs almost no setup.

I have create a web site and I need to read data which is created by rfid reader.
this device has some dll which can be use in windows application.
I want to know that is there any way to use those dll in my site in order that I read data from RFID reader? if not is there any way to use that device in web site?
Reading dll's on a clients machine is seen as big security risk and there is not really allowed. It is possible to use ActiveX controls (basically dll's compiled into cab files) which the user can then enable and download, this then will allow you to talk to the ActiveX control which talks to the dll's, which talks to the RFID.
I would rather suggest you use something like Silverlight with out of browser mode, which you can run on the client machine with elevated privilages, then you can talk to com object.
A much better way to go.
ASP.NET application is Server side application with specific security restrictions applied.
So basically, as the question is very generic so my answer too: you can do it, it's enough to be sure that your architecture fits yuor ASP.NET security/permission requirements.
Cause I immagine DLL is kind of COM component where you push signals and read alphanumeric characters specifying your RFID (passive or active) identifier.

I want to integrate SMS service with the software I am developing, so that users could send SMS to their clients.
Perhaps you can get actual SMS integration by sending an email ('[phoneNumber]#[carrierDomainName]'). This is how I integrated paging into my EventLog in the past. The cellphone domain name for each carrier shouldn't be too hard to determine. Verizon's is vtext.com.
Really the question that you need to ask is, which SMS service would be easiest to integrate with C#. Most of them out there have Web APIs, which would be easy enough to tie in with a C# application.
A few example gateways:
http://www.mediaburst.co.uk/api/
http://www.zeepmobile.com/
http://www.messagemedia.co.uk/
Of course, to send SMS this way will cost money (usually in the form of credits with your chosen gateway). If you meant to ask how can you interact with a physical phone to send messages, well that would all depend on the phone, it's o/s and software available for it.
Here is a list of SMS gateways:

Yeah Subodh i know your question, i also want that software as i am a LIC agent, well that would help me in managing my clients and policies...
well for more answers, search on google with keyword -- "sms api"
I'm guessing you want an API of sorts. Check out the following libraries:

I want to make a P2P Chat client, all I want it to do is to be able to send text across to each peer.
I looked at a Chat Client from this example:
http://www.geekpedia.com/tutorial239_Csharp-Chat-Part-1---Building-the-Chat-Client.html
And am wondering if it can be converted to a p2p program?
If so how can it be and can someone provide some code as it will help a lot.
If it can't how can I make a really simple p2p chat program?
Codes and examples will be very helpful.
btw I did look at this article, but it didn't help me:
http://msdn.microsoft.com/en-us/library/ms751502.aspx
I did a similar project once, only using bluetooth rather than Internet.
Mine wasn't chat so much as IM, since it only allowed for two people to converse, but we got it working by using the technique in brydgesk's edit and having the client ('talker') and server ('listener') together in the same application, in such a way that the server only puts out received messages to the local client, rather than rebroadcasting to all connections.
Hope this little bit is helpful, I don't think this is really the right place to help you write the entire application.
For P2P, you need to use UdpClient instead of TcpClient. Google should help you from here :)
Edit: Sorry, I made false assumptions in this answer. If you want to continue using TCP, that's just fine. Instead of creating a separate server application, add the server code to your client application, so that either the sender or receiver acts as the server.
If it is to be done on the intranet, why not use WCF named pipes?
