I understood Silverlight was drop by MS.
I create my first app permitting to read RSS in WindowsPhone and I need to add a reference to System.ServiceModel.Syndication.dll. In the doc http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh487167(v=vs.105).aspx, I need to find this lib in Microsoft SDKs/Silverlight/v4.0/Libraries/Client/.Why should I do it? Why I can't add directly a lib from the standard .net4?
Can you help me to understand.
[UPDATE]
When I add the lib from C:\Program Files (x86)\Microsoft SDKs\Silverlight\v4.0\Libraries\Client\
Visual Studio shows a windows "Adding reference to Windows Phone XNA assembly is safe. However adding reference to a silverlight assembly may lead to unexpexted application behavior. Do you want to continue.
So my assumption is this lib shoudn't be use but I don't find another way.
Maybe by add a ref from .Net 4 or 4.5.
Best regards,
Alexandre
The Windows Phone 7 SDK was built on top of Silverlight. For Windows Phone 8 this was changed so that there isn't a direct history with Silverlight but it was based on WinRT instead. Lots of functionality was made available to Silverlight controls to support backwards compatibility with apps written for 7.
Because WinRT is not compatible with classes written for the full version of the framework you cannot use these in your Windows Phone apps.
The warning you are getting is just a warning. It's telling you that your doing something that isn't an ideal and so you may have issues. Unfortunately there are no other versions of the SyndicationFeed object available to Windows Phone apps so you'll need to use this library if you want the functionality of SyndicationFeed without recreating it yourself. The good news is that there are no issue with using this class in your app. Just be sure to test carefully, on real devices, if you start to use other functionality from that assembly because, as the warning says: "there may be unexpected behaviour".

I have a DLL without source code and i want to convert it to windows phone DLL. I am stuck with its conversion, can any body help me? I have googled and found many links but none was useful. I tried to unblock the dll as well but that step also was not useful.
You cannot do that. The regular DLL uses the full .NET Framework. But the Windows Phone will require the ".NET for Windows Phone 8". The only way to convert between them is to get the source code and compile it.
NOTE: you cannot just take any app or DLL and try to put it on the phone. The underlying hardware, OS and platform are very different between normal computers and phones. Even if a functionality you want to perform is simple -- like find the length of a given string -- the underlying code that will run at the hardware level is very very very... different.
If it is .NET Dll you can try to decompile it. And than try to compile it for windows phone
In my Windows Store Application, I am getting the error:
Cannot find type System.Windows.Media.AudioSink in module System.Windows.dll
I tried to add a reference to it, but I can't find an assembly list in my project's references.
My system:
OS - Windows 8.1
IDE - Visual studio 2013
The .NET Core for Windows Store Applications does not include all of .NET 4.5 (nor 4.5.1). It is a subset of it, meaning that not all classes are included. It also has some classes specific to it.
If you want to do audio, you should look into the Getting Started with Audio and Video tutorial that Microsoft created for this very purpose.
Also, in the future you should probably include what language you are using. There are multiple languages that Windows Store Apps can be created in (C#,C++/XAML, Javascript/HTML), and it helps to know that.
I am new to PPAPI development and have downloaded the already examples from here
However, even after coming across the documentation,
I am not able to build the project.
I have Microsoft Visual Studio 2010, Windows OS and Chrome:30.0.1599.65
I understand that once a dll is created, using the regsvr32 command will register the plugin, although getting the dll, even with available code, seems tough for me. Any help for building the dll is appreciated.
You will want to start here to download the and set up the SDK: https://developers.google.com/native-client/sdk/download
This page will take you through how to build and run the examples: https://developer.chrome.com/native-client/sdk/examples
This page goes over how to actually create your own plugin: https://developer.chrome.com/native-client/devguide/tutorial/tutorial-part1
And then you should read this entire section to code and structure your application: https://developer.chrome.com/native-client/devguide/coding/application-structure
If you need any third party libraries be sure to check here: https://chromium.googlesource.com/webports
Edit: Forgot to mention that you will want to use the same version of the pepper api as the version of chrome you're running (in this case pepper_30). Also, you have to use the NaCl toolchain (one of either glibc, newlib, or pnacl); you can't use the Visual C/C++ toolchains. I recommend trying pnacl now that it is available, as that is by far the most cross platform version, but if you run into trouble, you'll probably want to use the newlib toolchain as it has better support.
I'm working my way through the MMVMCross Tip Calculator tutorial.
Got an Android instance up and running and have now turned my attention to Windows Phone 8.
So far, I can't find the Cirrious.MvvmCross.Plugins.Json assembly in the WindowsPhone bin folder, and I'm also having issues with the CreateApp() method not being able to resolve the Core.App class (there are a bunch of suggestions for chasing down the Core namespace but none of them have an App class inside that I can see).
When I comb through the docs it seems WP7 is supported explicitly, but no mention of 8. Anybody have any luck getting this scenario going? Is there a hack I'm missing?
After installing the Nuget package (The HotTuna Startup) in an Andriod project, I was unable to build and was getting the same problem in the CreateApp() where Core is not resolved. I had missed adding the package MVVMCross.Core and MvvmCross - Hot Tuna Libraries (which added the app.cs) to my core PCL library. Those Nuget packages are a great way to get started!
It's obvious now, but maybe this will help someone else.
Yes, Windows Phone 8 is supported, but there's no specific extensions for WP8 yet (e.g. we still use the Community C# SQLite code)
The Core.App class should be in your Core/application project. e.g. in the tutorial it's in https://github.com/slodge/MvvmCross/tree/vnext/Sample%20-%20Tutorial/Tutorial/Tutorial.Core
I'm completely new to Windows Phone and the Windows galaxy in general as far as programming goes. For a project of a phone app that has to run on a windows phone, I started exploring the resources and I have some questions.
One of the problems I encountered is that things change very quickly. For example, answers to this question say that browsers in Windows Phone will most likely not support HTML5. However, there are many online tutorials (for instance here) introducing ASP.NET MVC 4 and how it is appropriate for mobile apps.
I would personally like to go the "HTML5+javascript" way instead of learning how to develop with Silverlight, which apparently has been discontinued by Microsoft. However, my first concern is evidently to be able to create an application that works!
So with that in mind, my questions are the following:
My impression is that HTML5+JS is being introduced in replacement of Silverlight and will be more used in the future. Is that correct?
Knowing that I have to build an app which should be able to play videos and audio, record audio, and connect to a library to do some speech processing in the background, should I use Silverlight or can I try using ASP.NET MVC 4? (From what I gather, Silverlight would be better than XNA)
Are there limitations to using HTML5+JS as compared to Silverlight or the other way around?
Can you package a web app (i.e. using HTML5+JS) to be used locally on the phone if there is no access to a distant server?
Any specific pointers or answers on these specific issues will be more than welcome! :)
Currently, Windows Phone 7.1 does not support full HTML5+JS as a replacement for Silverlight. In Windows 8 (NOT the next version of windows phone, but the next version of Microsoft's desktop OS), HTML5+JS is presented as an alternative to using XAML and C# (it's a little confusing because on Windows 8, "metro" apps do not run Silverlight, but they still operate using XAML and C#). But that's neither here nor there... To summarily answer your question(s): In the phone's browser, there is very limited HTML5 capability.
From what you've described, you definitely want to use Silverlight for your Windows Phone app. The answer to that part of your question has never changed, Silverlight from the beginning of WP7 would be your best option. XNA is exclusively designed for gaming development.
To answer all of your questions, point by point:
My impression is that HTML5+JS is being introduced in replacement of
Silverlight and will be more used in the future. Is that correct?
This has not been confirmed (as of this post), but speculation is that this will be the case in some future release of the OS (no word on when that may be). But no, this is not currently an option, and there is no promise from Microsoft that it ever will be.
Knowing that I have to build an app which should be able to play
videos and audio, record audio, and connect to a library to do some
speech processing in the background, should I use Silverlight or can I
try using ASP.NET MVC 4? (From what I gather, Silverlight would be
better than XNA)
Silverlight. Silverlight. Silverlight. :) ASP.NET + MVC will not work. XNA is intended to be used for building games. Attempting to build more standard user interfaces using it would give you a migraine to say the least, and would not look anywhere near good.
Are there limitations to using HTML5+JS as compared to Silverlight or the other way around?
and
Can you package a web app (i.e. using HTML5+JS) to be used locally on the phone if there is > no access to a distant server?
As answered above, there is no way to do this on the phone.
As for pointers on all of this. I strongly encourage you to simply google (or bing if you're into that kind of thing) "getting started with windows phone" or "windows phone tutorials". Best source I could point you to is the Windows Phone Developer website. It's got some great tutorials that don't assume you know lots about windows phone. Best to get this material from Microsoft. It'll be more reliable, more well written, and ultimatly more useful. I've been writing Windows Phone apps since before the phone was released, and I still use it for learning the basics of something new. Great place.
