Known Issue – XAudio2 applications built with Windows 10 SDK do not work on Windows 8.x (Windows 10 Insider Preview SDK and tools, April 2015 release)
With this version of the Windows 10 SDK, applications built using XAudio2 will
require XAudio2_9.dll to be on the system, and it is not available for Windows
8.x.
Workaround: Deploy apps using the Windows.Networking.NetworkOperators and Windows.Devices.Sms APIs to a real Windows Phone device that is using an OEM developer account.

AnyCPU platform configuration is not supported for UWP applications built with C# and Visual Basic. Visual Studio 2015 RC uses .NET Native to build UWP applications. .NET Native compiles C# and Visual Basic code to native code and is therefore not CPU
agnostic.Choose a CPU specific configuration when building a .NET application on the Universal Windows Platform.

Cortana currently dismisses itself as soon as it loses focus. If you switch to Visual Studio when debugging a background voice command, Cortana will dismiss itself, end the connection with your app and kill the app's background task.
You can work around this issue by remotely debugging your app on a different machine. This eliminates the focus problem by allowing Cortana to remain in focus (on the remote machine) while you debug with Visual Studio (on your local machine).
Prerequisites
You have installed Windows 10 and Visual Studio 2015 RC on your main development computer.
You have installed Windows 10 on a separate computer or virtual machine (Visual Studio not required).
Note: Download Windows 10 from
http://windows.microsoft.com/en-us/windows/preview-iso-update-1504
Terminology
Your local computer is your main development box with Visual Studio 2015 RC and your project files.
Your remote computer is a separate machine that will run your app remotely while maintaining a connection with Visual Studio on your local computer.
Step 1: Enable Remote Desktop
Ensure your remote computer can receive Remote Desktop requests:
Sign into your remote machine
Right-click the Start menu and select System
Make a note of the machine name (you will reference it often)
Click the Remote settings link
Select the Allow remote connections to this computer radio button
Save and close
Step 2: Configure your Remote Desktop connection and remote microphone
On your local machine, start Remote Desktop Connection from the Start menu
Click Show Options
On the General tab, type of the name of the remote machine
Navigate to the Local Resources tab
Click the Settings button in the Remote Audio section
Change Remote audio recording to Record from this computer. This enables the remote microphone
Hit OK and navigate back to the General tab
Click Save As and save the Remote Desktop connection to a location on your computer
Connect to the remote machine
Step 3: Install Remote Tools for Visual Studio 2015 RC on the remote machine
Sign into the remote machine
Navigate to
https://www.visualstudio.com/en-us/downloads/visual-studio-2015-downloads-vs.aspx
Expand Additional Tools and look for Remote Tools for Visual Studio 2015 RC
Download and install
Configure the remote debugger as described at
https://msdn.microsoft.com/en-us/library/bt727f1t.aspx. Tip: Scroll down to “Start and configure the remote tools for the first time”
Run Remote Debugger from the start menu and keep the app running
Step 4: Enable developer mode on the remote machine
This step allows you to deploy and test apps to the remote machine. For details and alternate instructions see
https://msdn.microsoft.com/en-us/library/windows/apps/dn706236.aspx.
Remain signed into the remote machine
Run gpedit.msc from the start menu (this is the Local Group Policy editor)
Ignore the two popup error messages that will appear immediately
Use the tree view on the left side to navigate to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> App Package Deployment
Double-click and enable Allow all trusted apps to install
Double-click and enable Allows development of Windows Store applications and installing them directly from an IDE
Step 5: Enable Cortana debugging on the remote machine
This step disables the 5-second timeout when running a background task.
Remain signed into the remote machine
Run Debuggable Package Manager from the start menu
Copy/paste the following line exactly and hit enter: $a=Get-AppxPackage | Where-Object {$_.Name -eq "Microsoft.Cortana"}
Copy/paste the following line exactly and hit enter: Enable-AppxDebug $a
Type exit and hit enter to close the window
Step 6: Confirm you can connect to the remote machine with Visual Studio
Sign into the local machine and start Visual Studio
Click the Debug -> Attach to process menu (a project does not have to be open)
Type the name of the remote machine and hit enter
Provide your credentials (if using a Microsoft account, type your email display name and password, ignoring the domain text)
The connection is successful if you see a list of processes
Tip: If you experience a problem, make sure the Remote Debugger app is running on the remote machine
Step 7: Configure remote debugging in your Visual Studio project
Open your project in Visual Studio on the local machine
Open the project properties (e.g., right-click the project in the solution explorer and select
Properties)
Navigate to the Debug section
Select Remote Machine for the target device
Type the name of the remote machine
Close settings
If necessary, on the Visual Studio toolbar select Remote Machine
If necessary, switch to x86 or x64 depending on the remote architecture
Run
If prompted, enter your credentials
Switch to the remote machine over Remote Desktop and confirm the app shows up
Sometimes it will not show up during the first run; stop and restart
Set a breakpoint and confirm the debugger on the local machine is triggered
You should now be able to debug Cortana voice commands, including background commands. -
When implement a voice command as a background app, calls to modify voice command may not work as expected. For example, calling SetPhraseListAsync on a command set may result in a FileLoadException with the message "The process cannot access
the file because it is being used by another process."There is no workaround for this issue. You may modify voice command definitions from a foreground task or app.

To deploy to a Windows 10 Mobile device with this release, your device must be running Windows Mobile OS build 10074 or later. When deploying your Universal Windows app to a device with an earlier build, or a Windows Phone 8.1 device, you will get the following
error:
Error : DEP0001 : Unexpected Error: The Appx package's manifest is invalid. (Exception from HRESULT: 0x80080204)Use the Windows 10 Mobile emulator or update your device to Windows Mobile OS build 10074 or later.

When running the Universal Windows Platform (UWP) BackgroundTansfer sample (C# or C++) in a phone emulator (i.e., Debug Target is Emulator 10.0.1.0) the sample builds and deploys successfully, but clicking any button in "Scenario 1 File Download",
"Scenario 3 Completion Notifications" or "Scenario 4 Completion Groups" will result in the following exception:
An exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.ni.dll but was not handled in user code. Additional information: The system cannot find the file specified. (Exception from HRESULT: 0x80070002)
This posting is provided "AS IS" with no warranties, and confers no rights.I am getting the same error even with the references recommended here. This is my code
using (var stream = await Windows.Storage.ApplicationData.Current.LocalFolder.OpenStreamForWriteAsync(
JSONFILENAME,
CreationCollisionOption.OpenIfExists ))
serializer.WriteObject(stream, myCars);
I can read it back as long as I don't stop the app/emulator. When I run the emulator again the file is gone. I tried loading the app to my Windows Phone and the same thing still happens. -
If you have a type nested inside of a type deriving from a WinRT type, and the nested type is marked Serializable (such as with [DataContract]), your build will fail.
This code will cause this failure.
public sealed partial class MainPage : Page
public MainPage()
this.InitializeComponent();
var d = new DataContractSerializer(typeof(MyData));
[DataContract]class MyData { }Avoid serializable types nested inside of WinRT types.

When you attempt to deploy a windows 10 C++ Universal app that has a reference to a Windows Runtime component, to a Remote Machine (windows 10 machine), you will get an error message instead of successful deployment.
Right click solution, Go to Properties -> Configuration Properties -> Configuration - Uncheck "Deploy" checkbox for the Windows Runtime Component project. Then retry deployment to remote machine.

If you are using a serializer such as Json.NET, and use a custom SerializationBinder to handle type resolution, on x64 "Release" builds with .NET Native (C#/VB UWP) you will encounter corrupt parameters.
This code, if you pass it "assembly" and "type", will throw on Retail builds but work on Debug (CoreCLR) builds.
class MySerializer : SerializationBinder
public override Type BindToType(string assemblyName, string typeName)
if (typeName != "type") throw new Exception("type");
if (assemblyName != "assembly") throw new Exception("assembly");
return null;Add System.Runtime.CompilerServices.MethodImplAttribute to your BindToType method:
class MySerializer : SerializationBinder
[MethodImpl(MethodImplOptions.NoOptimization)]
public override Type BindToType(string assemblyName, string typeName)
if (typeName != "type") throw new Exception("type");
if (assemblyName != "assembly") throw new Exception("assembly");
return null; -
