i updated to 5.3, but now visual studio will not connect to unity
i get these errors but about 43 off them:
1\>D:\UnityWork\Desert Strike\Assets\Standard Assets\CrossPlatformInput\Scripts\Joystick.cs(3,19,3,31): error CS0234: The type or namespace name ‘EventSystems’ does not exist in the namespace ‘UnityEngine’ (are you missing an assembly reference?)
1\>D:\UnityWork\Desert Strike\Assets\Standard Assets\CrossPlatformInput\Scripts\TouchPad.cs(3,19,3,31): error CS0234: The type or namespace name ‘EventSystems’ does not exist in the namespace ‘UnityEngine’ (are you missing an assembly reference?)
1\>D:\UnityWork\Desert Strike\Assets\Standard Assets\CrossPlatformInput\Scripts\AxisTouchButton.cs(7,48,7,67): error CS0246: The type or namespace name ‘IPointerDownHandler’ could not be found (are you missing a using directive or an assembly reference?)
1\>D:\UnityWork\Desert Strike\Assets\Standard Assets\CrossPlatformInput\Scripts\AxisTouchButton.cs(7,69,7,86): error CS0246: The type or namespace name ‘IPointerUpHandler’ could not be found (are you missing a using directive or an assembly reference?)
the thing is i go to the place it says and the code it refers to is there. I do not use these scripts , but even if i delete these scripts it still complains, any idea?

Did you reimport the standard assets? It seems that all the issues you have posted are from those files.
Are those errors only shown in Visual Studio or also in Unity?

I assume you already did that, but just to be sure:
- Restarted Unity and Visual Studio, or your computer and open the project again
- Did you select Asset → Open C# Project (to regenerate the C# project files)
Did you try to open it in MonoDevelop, just to try whether this works?

I am having the same exact issue.
Just Updated to 5.3.1 and these errors started occurring.
I have tried restarting, uninstalling, and even resetting my OS. I think it is a problem with the standard assets for the update. Hoping for a solution.

Did you make a backup of the project and then reimport the standard assets?

Yeah I tried that. I eventually got it working by downloading the standard assets for 5.3.0. It even worked pulling the standard assets from 5.2. My issues only occur with the standard assets from 5.3.1
