Ever since installing Visual Studio 2015 Professional Update 3,
https://www.visualstudio.com/en-us/news/releasenotes/vs2015-update3-vs
I am unable to publish to any target at all. I repeatedly get informed:
Could not load file or assembly Microsoft.VisualStudio.ProjectSystem.DotNet.Internal - The system cannot find the file specified.
Has anyone experienced the same issue and managed to resolve it?
I have repaired Visual Studio: No Success I have reinstalled Visual Studio after deleting all files according to this link, with no success
I have ensured that all updates have been applied to Visual Studio: No Success
Can someone please help me?
Asked in thread below is the installed version of -net and I have not installed anything besides windows 10 and visual studio 15. 
I fixed it by reinstalling/repairing DotNetCore.1.0.1-VS2015Tools.Preview2.0.3.exe
Looking at a previous answer, I would guess that both the Azure SDK and the dotnetcore tooling previews both update the publish wizard components.
I solved this by re-installing Azure SDK Tools from here: azure downloads
