"No launchable projects are available for profiling" - Exception Solution


While I was developing an Application for Windows Phone and trying to use the inbuilt profiling option that was provided with Windows Phone SDK in Visual Studio 2012 IDE I came across the issue that the profiler is not attaching to the project but gives an exception "No launchable projects are available for profiling". Profiling and Application Analysis features in Windows Phone are really excellent add on’s that will be used widely when an enterprise level application is developed for Windows Phone. [more]

Exception: "No launchable projects are available for profiling"



In Visual Studio IDE, open the Debug menu from the list of menu available at the top and instead of selecting “Start Performance Analysis” we need to select “Start Windows Phone Application Analysis” will solve this issue. Basically the first option is the performance analysis for the Visual Studio event and its not specific for Windows Phone.


Hope this short tutorial tip will be helpful for you while developing your Windows Phone application.

How to take Screenshots on Microsoft Surface RT Device


Recently I got chance to upgrade my Microsoft Surface RT device from Windows 8 to Windows 8.1 preview and was trying to take some screen shots. Since Surface RT don’t have option to install the desktop application, was searching for some shortcuts to take screen shots of the device screens. Microsoft Surface RT provides option to take screen shots with some inbuilt key combinations. The same works for both Microsoft Surface RT and Surface Pro versions in both Windows 8 and Windows 8.1 Preview versions of the Operating System.   [more]


Press and hold the Capacitive Windows Button on the front of the Microsoft Surface Tablet and press the Volume Down button on the volume rocker. The screen dims for a sec and comes back to normal state which takes the screen shot of the screen from which the key combination is pressed.


Where Screenshots Saved?

In Microsoft Surface RT and Surface PRO, the screen shots will be saved in the same location which is My Documents –> Pictures –> Screenshots of the device local storage.

Hope this tip will be useful and effective for the Microsoft Surface Users.

To resolve this issue you need to follow the below steps, the exception is because of the application settings on the capabilities. This issue might be common across different other capability as well, so you need to activate the capability which we are planning to use it in our application development.     [more]


An exception of type 'System.UnauthorizedAccessException' occurred in System.Device.ni.dll but was not handled in user code




Open Visual Studio 2012 IDE and navigate to the project where the issue exists, now open the WMAppManifest.xml file under the properties section.


Go to the Capabilities section and select the appropriate capability, in our case we need to select ID_CAP_LOCATION from the list of available capabilities.


Save the project and build and execute the application to run in the emulator which will solve the issue. Hope this tip will be helpful for you and can be used in other capability fix as well.
