Woul like to develop an own application in C#

Thread Starter 
Hello,

I am a novice programmer who has knowledge in C and C++. I am thinking about developing an own application. Since I am not so skilled in programming I tried to look for something that could help. While I was searching I found a site (http://www.voip-sip-sdk.com/) with lots of sample programs. The sample programs are developed with the help of a software called Ozeki VoIP SIP SDK. However C# knowledge is needed as well and unfortunately I do not have the proper knowledge. Could you tell me how should I begin? Are there any useful books or tutorials? Hope you can advise me something.

C# should be relatively easy to pick up coming from a C or C++ background. I think the best way to learn is by doing - so download Visual C# 2010 Express to begin.
Not much beats MSDN IMO - http://msdn.microsoft.com/en-us/library/aa288436%28v=vs.71%29.aspx

While it might be best to sit down and completely learn a language before you use it, often times we have time constraints and an even shorter attention span. Since you have programmed before, you might be able get away with just trying to run with the examples on Ozeki's site. From what I can see, Ozeki appears to make extensive use of XML, so you might want to read up on the basics of XML which shouldn't take long (http://www.w3schools.com/xml/xml_whatis.asp).

You can start by reading through their online tutorial here first. Chapters I and II seem to cover pretty high level stuff, doesn't appear to be code specific. http://www.voip-sip-sdk.com/p_100-online-manual-voip.html

Once they get into the SDK, they walk you through how to install it. A lot of other SDKs expect you to know how to this already, so it appears they are trying to cover all bases. http://www.voip-sip-sdk.com/p_290-ozeki-voip-sdk-voip.html

The developer's guide starts off with a lot of theory, not too code specific. http://www.voip-sip-sdk.com/p_266-how-to-build-a-softphone-voip.html

If you have Visual Studio installed, you can download the first example and open the project by just double clicking on the SLN file.

http://www.voip-sip-sdk.com/p_121-c-sharp-wpf-softphone-configuration-voip.html

Follow the code line by line and comment each line as you go along. You might be surprised with how similar and simpler it looks compared to C and C++. Remember to expand the XAML files to view the (code-behind) CS files. If this is unfamiliar to you, I recommend reading this.
