C# and WCF , where to learn about it?

Its been a few weeks since I started learning C#, i know my way around visual studio, know things about classes, constructors, objects, played around with WPF and now think its time to learn some networking, say making a simple server/client application.
From what I understand winsockets are outdated and currently it is better to learn WCF ?
Maybe someone know some books, articles or tutorials about WCF for beginners where it would be explained step by stem from the ground up. :) Since all I was able to find were either rather complicated materials assuming that the reader it already a master-programmer or just coded supposed to be used as copy/paste without really explaining what it does.
Thanks! :)

In short, WCF is Microsoft's library of code to simplify the process of inter-machine and inter-process communication. Pre-WCF, there were a number of frameworks you could use. WCF gives them a consistent .net interface to simplify programming.
I recommend "Learning WCF", by Michele Leroux Bustamante. It's as thick as a Bible, but it has accessible material about the different facets of WCF with lots of code samples.

http://msdn.microsoft.com/en-us/netframework/wcf-screencasts.aspx
A very accessable group of tutorials, that cover the basics very well. Great place to start.

I would like to reccomend Pro WCF: Practical Microsoft SOA Implementation
- i've been learning with wcf with it.

I learned what I needed to know from the book Windows Communication Foundation Unleashed by Craig McMurty, Marc Mercuri, Nigel Watling and Matt Winkler. It has good examples that you can use to produce your own web services and such. It requires some knowledge of C#, which you seem to already have.

Go to MSDN my friend,If you have the patience to read the tutorials/articles in MSDN you can learn WCF very well.

Here are some good beginner tutorials from MSDN

Real winforms/wpf projects which use MVC, MVP, MVVM

I have looked some videos and read some articles about MVC, MVP, MVVM. I think, that I understood basic principles and differences. But it seems to me that samples in articles and videos are very easy.
I think that it's easy to learn how to apply these patterns when you can look on some projects.
So I'd like to look on real projects(Winforms/WPF), which use MVC, MVP or MVVM. Could you provide me links to sources of such projects? (If it is open source)
It will be great if projects will have unit tests for Controller/Presenter/ViewModel, because it's one of my problem when I develop applications.
Thanks in advance.

CodePlex will have a fair few http://www.codeplex.com/
I assume you have also used the samples at http://www.asp.net/mvc (you seemed to suggest this in your post)
Edit: also see these questions:

Repository Pattern in C#

I am trying to figure out the repository pattern for .NET. I think I have a pretty decent understanding of it, but I still don't feel comfortable using it.
I have googled for this topic, but found some advanced topics along with the repository pattern. What I am looking for is a basic knowledge of the concept, then I can build on it. With that said, can I get a recommendation of some good articles on the repository pattern?
Thanks

See the answers to Repository pattern tutorial in C#.

I recommend start by Fowler's definition
This concrete implementation could help you as well : )

Ayende's Rhino.Commons has a decent implementation.
I also benefitted from reading "Domain-Driven Design" by Eric Evans, which gives a good foundation of understanding the motivations behind Repository.

Have a look at following Article.
Using the Repository Software Design
Pattern
If you go through the whole series above, will be more help full

I'm in exactly the same position you were in. I found this Remondo.net blog post particularly useful. It walks through the implementation of a basic repository:

Best design pattern for complex silverlight games

What patterns do you think are best for silverlight games? Some main areas of focus are game performance, maximum number of objects reasonably updated in real time, ease of development and testing.

Actually the blog Shawn mentioned should be http://www.bluerosegames.com/silverlight-games-101/
I've been fighting this one for a while, and in XNA games I am leaning towards a Model-View pattern but in Silverlight I like using a combination of inheritance and composition that I detail here:
http://www.bluerosegames.com/silverlight-games-101/post/An-improved-Silverlight-Sprite-class.aspx
It just seemed that when I went to implement a Model-View pattern in Silverlight for games that it got in the way more than it helped. It could also be that I just don't understand the pattern well enough and I'd love to see if someone who's better at it to see if what I do is applicable to that pattern.

For ease of dev and testing, applying the MVVM pattern (which is widely used in the WPF community) will be of great help. But as for the the other pieces, I would read Bill Reiss' blog (http://www.bluerosegames.com/silverlightbrasstacks/) as he has done a lot in that area.

Good place to start learning ASP.NET

I have a two years of experience of programming in Visual C# and Visual C++. I would like to know some good online sources to start learning ASP.NET or anything else I should/need to learn before diving into ASP.NET. I found some online videos that are proving to be quite useful. Perhaps I would like to know about some open source projects where I can have a look at the ASP.NET code directly.

Sorry, but I'm going to have to suggest the immediately obvious first:
Official Microsoft ASP .Net Site
There's a link at the top to both "Get Started" and "Learn", and I have found this site incredibly useful over the past year or so.

Speaking as a convert from WinForms to the Web, I offer the following tips
Learn the ASP.NET Life-cycle
Get to grips with the concepts of client vs server-side code; know how pages are served up etc
Don't bite off too much too soon, there are A LOT of new things to learn, and it changes very quickly. But you don't need to be writing a full-blown AJAX web app straight away.

I like http://www.asp.net/learn/ it has some great tuts and some cool videos that walk you through the processes.
Good Luck

IMHO, CodeProject (www.codeproject.com) has lots of excellent articles related to ASP.NET.
Regarding projects, there are plenty of ASP.NET applications in CodePlex (www.codeplex.com) or SourceForge.
Regarding a specific ASP.NET application, http://www.cuyahoga-project.org/ its a great application to see.
Best Regards.

Loads of ASP.NET articles/tutorials at various levels. I found it pretty useful to get my head around some of the concepts.

Just to add, another great resource is www.learnvisualstudio.net
Its not free but it has a plethora of videos covering all aspects of asp.net from 1.1 to 3.5, AJAX, Webservices.
Programmer to Programmer style videos with great examples and downloadable source code.
Good luck :)
