VS 2015 Xamarin: Warning IDE0006 Error encountered while loading the project

I just followed the instructions but it did not eradicate the warning, although I ignored it, it does not appear now.

  1. When rebuilding the project, I noticed it takes a long time because it downloads a zipfile on your %userprofile%/AppData/Local/Xamarin/zips/*

-Make sure to not interrupt the build because it will stop downloading and will cause an invalid zip later on, thus reproducing this issue?

  1. Another hypothesis is that I included a component(referenced a dll) and then deleted it, and then re-added it. (as I'm having trouble with intellisense)

Firstly, it's not an 'Error' it's a warning.

Here's what actually happens:

  • Visual studio/xamarin check for required sdkbuild tools for your project
  • If you have it already in your SDK then no problem
  • If not, your project will show above warning in most of project cases.

How to fix this :

  • Clean your solution
  • Rebuild it (at this stage visual studio will automatically try to download zips)
  • If you get Rebuild canceled error, then close visual studio and start again
  • At this stage it will definitely download required zips.
  • Again Clean -> Rebuild -> Build -> Close the visual studio and open it again

Or Simplest alternative is

Download all SDKBuild tools available.

Your warning will be gone.

Let me know if it works, coz its worked for me several times.
