Answer 1

You probably will be using older version, that was having an issue. refer detail [here]

Install the newer web deployment tool, should work.

Answer 2

which .net version are you using.
check web deploy version. if vs has 2 web deploy version, the vs get confuse to take which version. If it has 2 version, just uninstall vs and then instal it along with web deploy. if the Vs has one 1 web deploy version, you uninstall and install the web deploy. It will rectify your problem i hope.

Answer 3

Check if version 9.0.0.0 of the assembly is installed in GAC. (from the VS2013 developer command prompt) gacutil /l Microsoft.Web.Deployment. Issues like this have occurred in the past where things worked, then after installing an update (or trying to install one) then reports of missing dlls, like nuget, occur.

The usual course of action is to repair the Visual Studio installation.
