Opening any Windows 10 UWP Project gives error for all "await" statements

I updated Visual Studio Community 2015 to Update 3 and since then, all "await" statements in UWP apps are throwing errors.

The errors I receive are -

The type 'IAsyncAction' is defined in an assembly that is not referenced. You must add a reference to assembly 'Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null,

The type 'IAsyncActionWithProgress<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null,

The type 'IAsyncOperation<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null,

The type 'IAsyncOperationWithProgress<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null,

For now, this is all that I have tried to - Clean install Visual Studio Community 2015 Update 3 along with UWP Tools 1.4, SDK 10586 and SDK 10240; manually reinstalling each SDK.

I uninstalled both SDKs manually and reinstalled them. The problem seems to be fixed lol.

I've had this error in the past too when I upgraded from VS version 1 to 2 I think, seem like this error was caused by me trying to upgrade instead of doing a clean install, I fixed it by removing VS and anything related to it from the control panel, then did a clean install and it was fixed.
