I've got the c# source for a DLL that works on windows 8... I would like to use it in a windows phone 8 application. Is there an easy way to change the target platform of the project to WP8 and then compile for that? I assume it will have to be compiled as a Windows Phone Class Library but that should be fine. I'm using VS2013.
Well it depends on the library. If it has any dependencies to the full .net framework, it will most likely not work. If its just a generic Library, you should be able to make a new Windows Phone Class Library Project and copy over the source.
I guess, you'd simply have to try that. Maybe you can bypass some of the dependencies and rewrite these sections with Windows Phone compatible code.

I have created the windows phone 8.1 application in which I want to use third party dll file. That's why I have created windows runtime component for the windows phone project. I have given reference of the runtime component to the windows phone 8.1 application project.
In windows runtime component, I have set the additional Include directory path. Moreover, I have also set the Linker -> Input ->additional dependencies as lib file listing. I have drag drop all dll files in my c# windows phone application main project folder and set build action as content and copy output directory as copy always.
However, I got the following error.
An exception of type 'System.IO.FileNotFoundException' occurred in App1.WindowsPhone.exe but was not handled in user code
I have checkout the following question. But did not resolve it.
How to use a C++ dll in Windows Phone 8.1 XAML App within C++ Runtime Component
I found the answer. All the dependencies has been set properly. There was an issue in the dll file which architecture does not match with the current platform.
After created the build for proper architecture, it works.
I'm having troubles while trying to add the Metadata of Autofac. I have to install the package "Autofac Extras: Metadata Attribute Support" which need Autofac.Mef. When installing this package, I get a message saying that I try to install Autofac.Mef 4.0.0 in a project targeting «portable-net45+win+wpa81» and that the package doesn't contain any file supporting this. (Same message with Autofac.Mef 3.0.3).
I could probably find a way to make my project work without Autofac's Metadata but I don't understand why this package isn't compatible with Windows Phone 8.1. Is there a solution to this issue?
Thanks in advance
Thomas
If you download the Autofac.Mef package manually and then open it up in NuGet Package Explorer you'll see that the Autofac.Mef package only targets .NET 4.5 apps - you can't use it in Windows Phone.
The reason for this is that the original framework MEF is only compatible with the full .NET framework. There's a "lighter weight" MEF 2 framework that is compatible with Windows Phone 8.1 but that's not the one Autofac.Mef works with.
There's no way to fix it. There's also no current plan to switch Autofac.Mef to using the Microsoft.Composition package.
I am making a Windows Phone 8 application, however because I would like at some point to also publish this application for Windows 8.1 store I made the effort to factor out the application logic into a portable class library. All good so far.
Now being a good boy I want to use an IoC container, unity by preference (since I am familiar with it in desktop and Win Phone 8 only apps)
So here's my problem; the NuGet Unity package will not install into my portable application with this result:
Installing 'Unity 3.0.1304.1'.
Successfully installed 'Unity 3.0.1304.1'.
Adding 'Unity 3.0.1304.1' to Logic.
Uninstalling 'Unity 3.0.1304.1'.
Successfully uninstalled 'Unity 3.0.1304.1'.
Install failed. Rolling back...
Could not install package 'Unity 3.0.1304.1'. You are trying to install this package into a
project that targets 'portable-net45+wp80+win', but the package does not contain any assembly
references or content files that are compatible with that framework. For more information,
contact the package author.
So is there a unity that works with a PCL? or is this just a shortcoming of the NuGet package?
I failed to find any useful documentation on the P&P website to indicate what platforms it is compatible with, but I know it does support WP8 at the least since the NuGet package is quite happy with libraries targeting just that.
Any guidance from the community would be very welcome here I don't want to abandon using a PCL for my app logic if I can avoid it, but if it comes down to a toss up between that and NuGet for package management I will in order to keep the NuGet goodness.
Could this be related to NuGet and Portable Class Libraries - Package doesn't target any framework? that seems more related to making your own NuGet packages for use in your own PCLs.
Unity 3.0.1304.1 does not contain any PCL assemblies so you will not be able to install it into a PCL project using NuGet.
The Unity NuGet package contains assemblies that target the following frameworks:
.NETFramework 4.5
.NETCore 4.5 (Windows Store/WinRT)
Windows Phone 8
You can see these target frameworks if you open the NuGet package into NuGet Package Explorer or download the NuGet package and open it using a program that supports zip files such as 7zip or Windows built-in zip file support.
So your possible options are:
Just use Unity in your main Windows Phone 8 application.
Write your own IOC container.
Use an IOC container that supports PCL projects such as Portable.CommonServiceLocator.
Compile your own PCL version of Unity.
Use a later version of Unity 3.5 since this includes a PCL assembly targeting portable-net45+wp80+win8+MonoAndroid10+MonoTouch10
Updated: 2014-05-11
Unity 3.5 now includes a PCL assembly that targets portable-net45+wp80+win8+MonoAndroid10+MonoTouch10 which will install into a project that targets portable-net45+wp80+win.
There is no Unity for PCL, but you can use Ninject for example.
I have a native dll that I'd like to use in a WP8 project that I'm working on. I've done some research and have created a C++ Windows Runtime Component (WRC) to wrap the native DLL. The WRC project uses a .lib file, and my WP8 application calls the WRC project.
My solution compiles all fine, but when my application makes a call to a method in the native DLL, I get a The specified module could not be found. (Exception from HRESULT: 0x8007007E) exception.
From reading around it seems like the dll is not being loaded. I've copied all relevant dlls to the output dir of where the .exe file is and also in various places but the error keeps showing up.
If anyone could point me in the right direction I'd be very grateful. Also if more info is required I'll post that up also.
The DLL must be included in your XAP package. Something you can see being taken care of in the Output window when you build your app, it starts with the "Begin Xap packaging" messages and then lists all the files that get added. The runtime error says it is not being included.
There is remarkably little guidance on how to ensure that a file gets included in a phone package when MSBuild cannot figure out the dependencies by itself. It certainly won't for your DLL, no way the build system can tell if it isn't a project in your solution. Seems you're operating a bit on the bleeding edge in this case :)
But this works well when I try it, going by the MSBuild output and not by actually testing it: Project + Add Existing Item. Navigate to your DLL and select it. Select it in the Solution Explorer window and look in the Properties window. Ensure that "Build Action" = Content, Copy to Output Directory = "Copy if newer". Rebuild, you'll now see the file getting added to the XAP. Which should solve this particular error. There might be others :)
Windows Desktop or Windows Store native DLLs are not binary compatible with Windows Phone, even if they are built for the same CPU architecture.
Therefore you will need to recompile your native DLL for the Windows Phone toolset.
About Windows Runtime Components:
On Windows Phone a Windows Runtime Component is itself a native DLL (.NET is not supported on the phone). The binaries of Windows Runtime Components cannot be shared between Windows Store apps and Windows Phone apps.
I am starting the development on windows phone 8, the famous JSON.NET does not support windows phone 8 yet, is there any other library which can be used for this purpose?
The JSON.NET codeplex site says that WP8 is supported.
Update: The JSON.NET NuGet package should just work with a Windows Phone 8.0 project. Adding it in VS2012 NuGet manager pulls in the WP7 version of JSON.NET. (packages\Newtonsoft.Json.4.5.10\lib\sl3-wp\Newtonsoft.Json.dll)
JSON.NET is now also available as a Portable Class Library which you can consume from WP8 (available in NuGet or in source form).
Had the exact same problem - turns out I didn't have the newest version of NuGet.
To upgrade, click tools -> extensions and updates and then click the Updates-tab. Update everything, restart the program and try again. :-)
I was having this issue. I was able to compile the source for Windows Phone 8 instead of Windows 7.1 and it worked. NuGet would not work for me.
Here is how I did it:
Open up solution JsonXXrXX.zip\Source\Src\Newtonsoft.JSON.WindowsPhone.sln
Go to properties for Newtonsoft.Json.WindowsPhone Project(Right click on the project then properties)
For the dropdown of "Target Windows Phone OS Version" select Windows 8.X
Compile.
Grab the DLL, PDB, and XML from the output directory
Add Reference to the DLL file in your Windows Phone 8 Project
Thats it. I can't vouch that it works 100% or that you'll be able to submit your app. But it should hold you over until there is official support.
For complex json you might find this website helpful: http://json2csharp.com/#.
If you don't wanna make too fancy stuff (or need dictionary) suppport, you can also just use the built-in DataContractJsonSerializer (http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer.aspx)
Btw: At least in https://json.codeplex.com/discussions/401305 some people report that the WP7.1 dll works for them, using this file: "Newtonsoft.Json.4.5.7\lib\sl4-windowsphone71\Newtonsoft.Json.dll".
