Edit

Also there is not Emulator in the Device list.I think error is due to this once.I have download the 8.1 Emulator but cant find in the VS 2013 Emulator list.

Answer 1

I used function 'Repair' in control panel -> programs and functions -> Windows Software Development Kit for Windows 8.1 ->Change and solved this problem.

Answer 2

In my case I had to install Windows Software Development Kit (SDK) for Windows 8.1 (Not Windows Phone SDK!) to fix it. I have VS2013 update 4

Answer 3

have you checked for the existence of a SYSTEM level environment variable called windowsSDKDir? and try removing it?(make a note of its value first in case you need to re-instate it at some point). For some this appears to have been causing the error. It is not clear at this stage what creates this.

Answer 4

Extracts from msdn discussion:

check for the existence of a SYSTEM level environment variable called windowsSDKDir and try removing it.

For this Follow these steps:

Press Windows Key + X and select System.
In the System dialog click on "Advanced system settings" then click "Environment Variables" on the advanced tab.
Then look for the environment variable I mentioned
try removing it

If this not works for you ,you must re-install, Windows Software Development Kit (SDK) for Windows 8.1 this must solve your problem.

Answer 5

The issue seems to be bound to the VS2013 Update4. I had no issues before, but after this, I needed to Install the Windows Software Development Kit for Windows 8.1 as Ludwo suggested.

Answer 6

Some basic checks you need to perform to get anywhere close to a resolution.

The Windows.props file is a build file that's used by MSBuild.exe when it builds a Windows Phone app. The normal install path is C:\Program Files (x86)\Windows Phone Kits\8.1\References\CommonConfiguration\Neutral\Windows.props. Use Windows Explorer to check if the file is present.

Then there is a line in the main .targets file that includes it. It tries to locate the file in the $(TargetPlatformWinMDLocation) directory. You can see the value of this macro by increasing the build verbosity. Tools + Options, Projects and Solutions, Build and Run. Change the "MSBuild project build output verbosity" setting to Detailed. Use Build + Rebuild on your project. Scroll back the Output window and locate the lines that resemble this:

1>TargetPlatformSdkMetadataLocation = C:\Program Files (x86)\Windows Phone Kits\8.1\References\CommonConfiguration\Neutral
1>TargetPlatformSdkPath = C:\Program Files (x86)\Windows Phone Kits\8.1\
1>TargetPlatformSdkRootOverride = 
1>TargetPlatformVersion = 8.1
1>TargetPlatformWinMDLocation = C:\Program Files (x86)\Windows Phone Kits\8.1\References\CommonConfiguration\Neutral

Tell us if you see anything different.

This path is read from the registry. Startup Regedit.exe and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SDKs\WindowsPhone\v8.1\Install Path as well as HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SDKs\WindowsPhoneApp\v8.1\Install Path.
Verify that you see a value listed in those keys with the name "Install Path" and that it contains the value "C:\Program Files (x86)\Microsoft SDKs\WindowsPhoneApp\v8.1\".
