Any suggestions on how to solve this problem?

I got a similar error message when trying to create an MVC Web App on VS2015. Found this solution and it worked for me.
Hope it helps.
On VS2017 go to "Tools-> Extension and Updates" then find and Check "Xamarin for Visual Studio", it was disable, i enabled it, and restarted. Worked for me.
