I am starting to develop a Windows phone (Silverlight) 8.1 application and one thing I wanted to create was a user control. I noticed on the normal windows phone templates for a WP project in VS2013, there is a template for user controls, but not when in a Silverlight 8.1 project. What would be a good starting point for this? Is it the same as a windows phone user control? I am having a hard time finding tutorials on how to do this specifically for Silverlight.
This is a new Windows Phone 8.1 Silverlight project and these are the options you see. I believe a Windows Phone User Control is what you want.
The naming conventions changed probably because the new non-Silverlight Windows Phone User Control uses the WinRT naming convention, using: instead of clr-namespace:, so these components are not shareable between Silverlight and non-Silverlight projects.

I have a simple question : Is it possible to create a windows 10 app (tablet for my case) in WPF instead of UWP ? Because actually my app need a framework that allow to create pdf, but none free framework exist in UWP yet, but un WPF this is quite different. Thank you.
WPF apps are fully supported on Windows 10, so nothing stops you from using WPF instead of UWP!
In fact, you can even take advantage of UWP features in WPF apps by using the Desktop Bridge (Centennial)
I have old app creted in Windows Phone Silverlight 8.0. I use RadDataBoundListBox (Telerik Controls) for list in app. I need add drag&drop function in my app.But it was not easy.
RadDataBoundListBox do not support drag&drop.
In Silverlight 8.0 work with drag&drop difficult and complex.It is only example drag&drop for list in WP Silverlight. But it does not suit me.
I can upgrade app to Wimndows Phone Silverlight 8.1. But ListView is not available for WP Silverlight 8.1. Which control should I choose for drag&drop and reorder?
I have a time limit. Please tell me the fast way to solve this problem.
I would recommend ListBox, reorder can easily be done using linq extension.
If you have an extremely large list you should be careful with listbox.
for drag and drop look at Drag and drop from list to canvas on windows phone with MVVM
Look at drag and drop in windows phone and https://blogs.msdn.microsoft.com/pakistan/2013/07/10/drag-drop-in-silverlight-for-windows-phone/
I searched for information about it for two days. Add full drag&drop for items in windows phone silverligth - It is inpossible. May be used reorder. It is a great control for wp silverligth(only reorder). I will update the project to windows phone 8.1.
I know that XAML is used for designing UI in combination with Blend. I am confused with so many terms, like, how XAML comes into play for WPF, Store App, Phone App or UWA. Morever, what is the difference between WPF, Store App, Phone App and UWA. Does all that means that old Desktop Project will no longer be used and replace by either WPF or Store App or UWA?
When .NET was released in ~2000, you could use WinForms to make desktop applications for Windows. It provides access to 'native' controls (i.e. A Button made in WinForms actually is a Windows Button control from user32.dll) by wrapping the Windows API in managed code. These can run in any version of Windows which has the appropriate .NET framework version installed, including upto Windows 10.
In 2006, WPF was released which is an alternative to WinForms. WPF uses XAML, which is a language based on XML, to declare the user interface elements. In a simple WPF app, the .xaml file describes the GUI and the code-behind file describes the logic. DirectX is used to draw whatever is described in the .xaml into the window.
Like Winforms, programs made using WPF can run in any version of Windows which has the appropriate .NET framework version installed, including upto Windows 10. Note that using XAML is completely optional. Whatever user interface elements you describe using XAML can also be made using your .NET language C# or VisualBasic.NET. But using XAML is usually simpler. See To XAML or not to XAML (MSDN Blogs).
From XAML (Wikipedia) :
As XAML is simply based on XML, developers and designers are able to share and edit content freely amongst themselves without requiring compilation.
From ~2012 along with Windows 8, a new kind of app called metro/modern/windows-8/windows-store-apps can be made. These apps are similar to WPF in that they use XAML for describing the GUI. These apps can run only in Windows 8, 8.1 and Windows 10. Windows 8.1 added some improvements and features but remained mostly the same. The same technology was used to make apps for Windows Phone.
With the release of Windows 10, Microsoft made UWP (Universal Windows Platform) through which you can use the same code base to target differnt kinds of devices (desktop/mobile/xbox/IoT/holographic). These apps made for the UWP are similar to the earlier Windows 8/8.1 apps. Like before, XAML is used to describe the GUI.
Only for the Windows Store apps, there is no backward compatibility. The timeline goes Windows 8 -> Windows 8.1 -> Windows 10/UWP. An app made in UWP can only run in Windows 10 and an app made in Windows 8.1 can not run in Windows 8.
I would highly recommend referring to this discussion thread in stopbyte, it has far more details and explanation of the concepts behind WPF, UWP And WinRT.
As for WinForms, from my experience it's history now. Have been almost replaced by WPF (though it still has mainstream support as mention by #Jazimov).
I'v noticed that Microsoft has stopped improving Windows Forms and probably has stopped maintaining it as well.
I am abit confused about interoperations between forms. I have an c#.Net application developed using DevExforms. On the other hand I have a XNA application which I want to use it as 3d GUI. But it is diffucult to interact between them. Of course it is not useful, it is ugly too.
So I see a way to develop 3d model viewer app using WPF but WPF controls and windows forms controls needs .Net Framework 4.5 to interact betwwen. But I must use VS2010.
So I am confused. What must I do. How can I easily develop a 3d app with Windows Forms or how can i interact any platform with my app. Actualy if you were me what will you do?
WPF controls and WinForms controls don't need .Net framework 4.5 to work together. the interoperability exists before (4.5). take a look in MSDN
As I understand, WinRT is a different version of WPF written without using the underlying Win32 APIs.
What's the relation of WinRT and WPF? Will WPF work under Metro in Windows 7 or will it launch the classic desktop?
That's not so clear from the Keynote. If someone has Windows 8 installed can confirm it's behaviour.
Thanks
WinRT is a replacement for the Winapi. The api is native, very unlike WPF that runs as a layer on top of the CLR. It certainly resembles WPF, part of what causes confusion. It adopted the metadata format of managed code, replacing type libraries of old. And uses XAML for UI designs, much like WPF, Silverlight and Windows Phone. You can still write WPF apps for Windows 8 but your app can't be published through the store, won't integrate with the Metro desktop nor will it run on tablets that are based on the ARM core. Whether that's a real problem depends a great deal on how well Metro will do in the market place.
There is no relation between WPF and WinRT, just like there is no relation between Silverlight and WPF. Now we have three technologies, WPF, Silverlight and WinRT.
If you try to execute WPF application, it will not execute on Metro, it will execute in the classical desktop only.
In Visual Studio 2011, you have WPF and Metro as two different types of applications, and Xaml for WPF and WinRT is not same, Xaml for WinRT is pretty much same as that of Silverlight as lot of classes which exist for WPF are missing in WinRT library. But most of classes that exist for Silverlight are available in WinRT.
Windows Runtime (WinRT) is an alternative API used to create Metro Applications
(and later server application).
The APIs are class/method/struct based and surfaced to .Net metro apps, html5/css3/javascript apps and C/C++ metro applications.
The implementation is native.
APIs are made visible via .winmd files, which contain metadata very similar to the metadata you have in .Net assemblies.
The APIs are designed to secure and async friendly with many APIs requiring the use of async/await due to them potentially taking more than 50msec to execute.
It includes a subset of Win32 APIs and COM apis.
Anyway... the followings links help... channel9 also has some //Build/ videos on the subject..

WinRT is a new library that you can use XAML, but not WPF.
WPF is primarily uses DirectX for visual.
You can use WinRT with:
XAML
C#
C++
VB.NET
HTML/JS/CSS
WinRT is a non managed API based on COM interfaces. You use it by calling objects buit in .winmd metadata files ( Windows\System32\WinMedataData directory).
All the namespaces begin with "Windows.".
You can write your Windows 8 application by using XAML files, but that's the only common point with WPF.
