Error while compiling solution - namespace missing while it is not

Vote count:

I'm trying to build a solution downloaded from TFS, but I get many errors (in the form described below), all related to missing namespaces.

I am sure the namespaces are not missing though. The solution builded correctly once per new machine, but then failed due to missing namespaces, even if they can't be missing if the solution did build just moments before.

To solve the issue, amongst other things, I've installed a fresh new version of Windows 8.1 (with all updates) and then VS 2013 up. 4. After restoring all NuGet packages the solution builded without errors once. All subsequent efforts to rebuild it led again to the same errors.

I even tried once again with a new install from scratch, this time disabling auto updates in win 8.1 x86 with Update, and VS 20134 up. 4, but again the first build went fine, and the subsequent all failed with the same errors.

The errors I got where all in this form:

Error   1   The type or namespace name 'xxx' could not be found (are you missing a using directive or an assembly reference?)   c:\Users\xxx\Source\Workspaces\xxx\App.Shared\Common\LicenseManager.cs  21  26  App.WindowsPhone
