Visual Studio 2015 Xamarin deploy fail without any error message

Question

I just installed VS 2015, the installation was finish (after some fail time caused by the slow network, I run setup again).

I create a project as Adroid > A

Answer 1

And yet another recipe of fixing this:

• clean projects
• remove all bin, obj folders
• mark your android-project as startup

then try to deploy again

As for me, in some cases, if visual studio stucked on project building, it requires pc reboot.
