Im developing a Desktop app with WFP, but I've to migrate it to UWP Windows 10. Does anybody knows what this conversion involves? How complex is it?
Thank you in advance for the help :)
XAML for WPF and WINRT is not same because lot of classes which exist for WPF are missing in WINRT library. So the porting may have lots of work to do.
This may be helpful to you: https://channel9.msdn.com/Events/Build/2015/3-741
If you are going to convert it from WPF to UWP be sure to keep an eye out for the next few things:
ASync calls
a framework with less options but same possibilities
depends on your code and programme, but if you are experienced it might only take a few hours :)
.NET in WinRT is a lot more limited than the one in WPF.
So the level of difficulty of porting directly depends to your app's functionality.

I am new to this AddIns architecture but it really seems fascinating to me. I downloaded shardevelop code to understand it but it is too huge and the examples given are using Winforms. I want to use WPF. Can you please provide me some links where they have used sharpdevelop with WPF?

In most cases, SharpDevelop code base is your best resource.
BTW, did you check out MEF from Microsoft?

I am Really confused by reading some articles about Silverlight. Whether I should concentrate on WPF or Silverlight or Both?.
It's like asking Web or Desktop : Which one has upper hand?
Silverlight (Web) and WPF (Desktop) Both are similar. But both have their separate workplaces.
You cannot have a Windows Calculator, Task Manager or MS Word (please don't mention google docs) applications on web like they are on desktop. And same thing applies for web applications.
So, it depends on what platform you want to work on.
I dont think its difference between Web and Desktop. Silverlight is still pretty limited by platform it can run on and still requires some local runing process, even in the sandbox.
I think difference here is features vs availability. WPF can give you features of whole .NET framework, total acess to users's computer and some features that are not available in SL. SL on the other hand allows you to run your app on some different systems (Windows, Mac and there is limited support for Linux-based systems), distribution is much easier thanks to web deployment and whole application can be part of your web ecosystem.
Iam personaly for WPF, but thanks to this whole web and cloud-hype in the last years, SL is getting much more attention from side of MS and developers in general.
Reading these questions and their answers may give you some insight into this:

What is the difference between WPF and Silverlight?
I totally agree with decyclone, it depends on which platform you want to work. If you have prior experience Asp.net/We applications Silverlight is the way whereas if you have worked in WinForms/Windows applications then WPF is the way to go.
But yes most of the concepts in both SL and WPF are similar; so once you have good understanding of those concepts, you work in either without much problem.
If we ignore the platform then WPF is having the upper hand as WPF is kind of superset of SL.
Have a look at this SO question too -
Learn Silverlight or WPF first?
I am a 6-years .Net Developer, and want to know which is better to start learning first, Silverlight or WPF.
I know this question seems a little-bit argumentative but since Silverlight is a mini-version of WPF. I think this takes away the argumentation.
So in the light of that, if I considered start learning:
Silverlight First: Because it would be easier to learn than its big brother.
WPF First: Because it would be easier to know the basic concepts and event-model of WPF before moving to SL.
Learn Silverlight first so you won't be annoyed that you cannot use useful things like RelativeSource and x:Static in Silverlight :P
Silverlight will be fused with WPF in a couple of years.
Study Silverlight first, i recommend the book Pro Silverlight 4 in C# from Apress, the unique that have color pages.
If in future you'll need some extra Windows functions, go to the much complete WPF.
With Silverlight you can also develop Windows phone 7 applications, and Xbox 360 (rumored). In windows 8 will be a Silverlight Marketplace (valid rumor), and you can create very rich applications / part of website / full websites instead of using the slow, crappy and "browser inconstistent" JQuery+Canvas that have no tools at all for design (and when it will have, Silvelight 5 will have real 3D and better tools).
Also the fact to use the same language for client and server is priceless.
Well Silverlight and WPF is "pretty much" the same actually. As you said Silverlight has only a subset of the .NET framework but it doesn't make it "simpler" than WPF.
The biggest leap you will have to make in order to learn those languages is learning XAML, which is the same in both.
It all depends on what you need to do. Do you want to publish your project to the web, then go with silverlight (you can do a XBAP project in WPF to publish it to the web, but clients will need Full .NET Framework). If you need advanced .NET functionnality, then use WPF.
Silverlight first. It is easier to add the extra WPF features than to unlearn things when doing WPF first.
Having said that, it doesn't matter that much. There is more on Silverlight on the web these days.
What kind of applications do you want to write ? Desktop applications that need local access or web based applications ?
If it is a matter of learning, I would learn both in parallel. Keeping your application consistent to run in both run times will force you to learn all of the little differences. Once you get past the main SilverLight features, shift into the features only provided by WPF (though I would start with the libraries likely to be included with SL5, first, such as 3D).
Go with Silverlight first, although it is not as feature rich as WPF it is simpler. Also Microsoft are actively evolving the platform. Silverlight is not a true subset of WPF as it had things like a DataGrid control first.
Good learning resource: http://www.silverlight.net/learn/ together with the Pro Silverlight book which you already have.
The further advantage of starting with Silverlight is that it will be easier to develop for the new Windows phone (broadly it uses an older version of Silverlight).
Learn both at the same time! Not one or the other, but both. There's plenty of overlap between the two technologies which should make it more practical to focus on both at once.
If I wanted to create some Silverlight widgets and host them within WPF is this possible?
I've searched for examples & found a few concepts online but no approaches that actually panned out / work / and a bunch of dead links.
Has anyone successfully done this or any ideas for how to do this? Any help is appreciated.
You can try my SilverlightViewport project. It allows for rendering Silverlight programs in WPF. Should support all versions of SL.
The brute approach would be using the WebBrowserControl. Other than that, I don't know. Maybe you could unzip the .XAP file and try to load the XAMLs and Assemblies you would find. ;-)
What features specific to Silverlight do you use in those widgets? Is there a real problem with making them work in both Silverlight and WPF and compiling 2 versions?
Is it possible to convert an existing WPF Application to SilverLight automatically/with minimal effort?
I would argue that you CAN port Silverlight to WPF with minimal effort. I spent 2 hours porting and application I spent 3 weeks writing. I would argue that those 2 hours spent would categorize as minimal effort.
Sure, you need to create a new project, add the files to the new project and tweak them.
Since Silverlight is a subset of WPF its allot easier to go from Silverlight to WPF than the other way around.
For business logic and non-UI code your code should port almost straight across. I had some minor issues around authentication, as Silverlight 2 will pick up any authentication information in the browser, while in WPF you have to role your own login screen and manage cookies etc.
For the XAML it will port straight across if you don't style your controls. If you style your controls the use of the Visual State Manager, currently missing in WPF, will make things a little trickier. You can either re-style your controls in WPF using Triggers, or you can use the VSM implementation for WPF done by John Gossman. Microsoft have announced that they will add the VSM to WPF to make the two frameworks more compatible.
The perhaps most important reuse tough, is skills and experience. Since the two platforms are so similar you will be able to reuse all your skills in WPF.
I recently did a blog post about the Dive Log sample application and how I ported it from Silverlight 2 to WPF. Might give you some idea of the process.
Not really. I have found some articles regarding the multi-targeting option for WPF and Silverlight at the same time. At this moment, if you are not using PRISM, it is quite a challenge to target both of them, fortunately achievable.
What do you need to have in mind is that Silverlight uses a smaller (thus more limited) library than WPF.
In response to the comments:
Actually, there is already support for silverlight in PRISM (v2). The idea of PRISM is to provide guidance to developing applications not only using WPF but using Silverlight also - Prism V2 formally was known as Composite Application Guidance for WPF and Silverlight.
By using PRISM for silverlight capabilities, it would give you the warranty that your code would work on both platforms with minimal changes, if none (except maybe the different project types for visual studio).
But of course, if you already started developing your application, you would need to change your code to use PRISM.
Will and Bogdan's answers are correct. The keyword here is "minimal".
Rob Eisenberg has a list of differences here (though this was pre-RTW).
List of Differences in WPF & Silverlight
No. Silverlight runs in its own cut-down version of the CLR. It also is WPF-like, not WPF. You'll have to do a fair amount of work to convert it.
Times have changed. Check out Portable Class Libraries, now supported in .NET 4.0. You can build assemblies that can be used on different supported platforms: WP7, Silverlight WPF and even XBOX applications.
