Unity and Windows 10 Universal

Hi,

I have a problem with opening project in Visual Studio 2015 after building. I get error that the project cannot be loaded.

After reloading I get message in output:

C:\UnityProjects\CardGameTemplate\UWPBuild\Card Game Test\Card Game Test.csproj : error : Object reference not set to an instance of an object.

I did not alter files after building. Anyone had similar problem?

it looks like some csproj files got duplicated found my solution here
