I'm using the MvvmCross framework to create a windows phone 8 project.
In my WP8 project within the xaml I have the following:
<i:Interaction.Triggers >
<i:EventTrigger EventName="Tap">
<Commands:MvxEventToCommand Command="{Binding OnItemTappedCommand}" />
</i:EventTrigger >
</i:Interaction.Triggers>
My namespaces are as follows:
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
and
xmlns:Commands="clr-namespace:Cirrious.MvvmCross.WindowsPhone.Commands;assembly=Cirrious.MvvmCross.WindowsPhone"
When I attempt to build I get the error:
Cannot resolve dependency to assembly 'System.Windows.Interactivity, Version=3.8.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.
Looking in ILSpy I can see that Cirrious.MvvmCross.WindowsPhone.dll references this dll but I only have version 3.9.5.0 available in my assembly references list within my project.
I've tried adding an assembly redirect in my app.config but I think that's more for runtime resolution then for build errors.
What's the best way to resolve this issue?
Thanks
-- EDIT --
I've managed to resolve this issue by finding a WP7.1 version of the System.WindowsInteractive.dll which is version 3.8.5.0. My project is definitely targeting the Windows 8.0 phone OS.
Could this be a problem with the Nuget packaging of MVVMCross?
Just to answer this question since I came across this problem today...
I had a fresh install of Windows 8.1 and the Windows Phone 8 SDK. My sln would build but when MvvmCross resolved the plugins on start-up it would crash with a ReflectionLoadTypeException - the LoaderExceptions property contained a single entry - it was unable to find System.Windows.Interactivity, despite being referenced from the extensions list in the reference manager for the project.
The solution was to install the Windows Phone 7 SDK and grab the Windows Phone 7 version from C:\Program Files (x86)\Microsoft SDKs\Expression\Blend\Windows Phone\v7.1\Libraries\System.Windows.Interactivity.dll.

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 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.
It is a windows phone project and it was working fine until I taught to implement the Payment Reports in it and upgraded to the 1.4 now I added the reference using the nuget package found here http://www.nuget.org/packages/Google.Apis.AdSense.v1_4/ chnaged the v1_3 to v1_4 and now I keep getting this error.
Error 1 Cannot resolve reference assemblies. Please check the reference assemblies. Cannot resolve dependency to assembly 'Google.Apis, Version=1.7.0.24060, Culture=neutral, PublicKeyToken=null' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.
I tried uninstalling the Nuget Package from the Nuget Manager completely and then Installed v1_3 again but now even this has stopped working...please can you tell me where did I go wrong?? and how to fix this issue now...
I'm trying to use the sqlite-winrt library at https://sqlwinrt.codeplex.com (cf. http://blogs.windows.com/windows_phone/b/wpdev/archive/2013/05/30/sqlite-winrt-wrapper-for-windows-phone.aspx) because I need to access an SQLite database via SQL commands in a WinRT 8.1 and a WP8 app and this library seems the only available option.
Anyway, there is no binary release and if I try compiling the source I get several link errors for unresolved externals against the SQLite DLL. I posted an issue at codeplex but got no reply yet, so I was wondering if anyone had already managed to successfully compile this lib and how (or if you know of any viable alternative for RT8.1 and WP8). Here is what I did:
downloaded the latest source from the site.
downloaded and installed 2 VSIX from http://www.sqlite.org/download.html: sqlite-winrt81-3080002.vsix for RT 8.1 and sqlite-wp80-winrt-3080100.vsix for WP.
executed the powershell scripts in each subfolder of the source code solution, which are required to update the projects with newer releases of the SQLite for WinRT extension. The current versions of the scripts refer to SQLite for WinRT 8.1 (prerelease) which is the same I downloaded above.
opened the VS2013 solution and removed the RT project (I just need RT8.1 and WP, this was for WinRT 8.0).
5) built the solution, which failed with link errors.
If I see the RT8.1 project properties, I can confirm the reference to SQLite is under C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1\ExtensionSDKs\SQLite.WinRT81\3.8.0.2.
Did anyone manage to use this lib? Thanks!
I also once had that problem. I fix it by editing the project file manually. At that time, the powershell script updating the wrong path. That's why I always failed when compiling my project. After I edit the project file using external text editor (I use sublime text), the projects are linked correctly.
You can try DatabasesCx. It is another SQLite Wrapper using Windows Runtime Component technology. It is freeware distributed as precompiled binary. You can find the details at http://www.almanacsoft.com/databasescx
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.
