.NET Core 1.0.0 was released yesterday and it needs VS update 3 to be installed.
So I downloaded the installer from here and tried installing but this weird issue is happening:
It's as if the installer is trying to get update 2 instead of update 3. I'm already on update 2 and it's telling me that. I tried searching but didn't find anything on the subject. Also tried restarting my machine.
And now I'm being blocked by this since I already uninstalled .NET Core RC2, and .NET Core 1.0.0 doesn't want to install before VS update 3.
Forget the downloaded update, just go to Programs and Features, double click Visual Studio 2015 Update 2 and choose "Modify" from the VS installer options. Update 3 will be available there.
After downloading the full installer Visual Studio 2015 Update 3 - ISO I ran it from admin command prompt with vs2015.3.exe /Passive
With the /Passive switch it finally installed the upate!
A workaround is to not use the download. Instead, open Program and Features from the Control Panel. Select "Visual Studio 2015 with Updates" (or your equivalent), and click Change. From the installation dialog, click Modify and you should see Update 3 available to be selected.
I faced this problem I solved it by downloading the offline iso file then installed it from the iso file
you can find offline iso file http://www.kunal-chowdhury.com/2016/06/visual-studio-2015-update-3.html

"Workaround:
Instead of installing Visual Studio 2015 Update 3 by using VS2015.3.exe, install the update by using a full product installer. You can find installers for "Visual Studio 2015 with Update 3" on the Visual Studio download page. Select the "Visual Studio 2015 with Update 3" download that matches the edition you already have installed, whether Community, Professional, or Enterprise.
Alternatively, you can follow the steps in Updating an installation to force an update to the layouts."
