Unity: Fix IntelliSense and Error Checking in Visual Studio

This video shows a quick way to re-link Unity and Visual Studio to fix:
- errors not showing up
- Unity-specific code not being recognized
- IntelliSense / Autocomplete for Unity code

If you see "miscellaneous files" rather than "Assembly-CSharp" at the top left of your Visual Studio Script this is how you fix it.

300 Random forum posts weren't able to fix the problem, but you were. Thank you so much, you have no ideia how much i appreciate your help

Thank you so much! I was puzzling for so long, browsing through Google on what to do, even trying to figure it out by myself. Such a clear and easy explanation.

Trying to self-teach/learn coding, having Visual Studio show you where errors are is so helpful. I updated Unity and was completely lost as to why VS was doing this. Lost the entire day trying to find the fix before finding your video rather late in the night. I've stared at experimental lines racking my brain trying to figure out why the compiler is running into errors only to finally look at the error list and see I'm missing a parentheses or a semicolon somewhere. THANK YOU!

Thank you! I was so confused on why this wasn’t showing up! This really helps!

Thx, really huge help.
For futre reference to other ppl:
- try making sure the "Embeded Packages" and "Local Packages" boxes below in Preferences > External Tools are also checked
- uninstall and then reinstall Visual Studio extentions such as the "C#" one

I have a problem with visual studio that some times gives me false errors and won't update checking the errors

[Greg-ihfz]

If you still have such problem just try to reload project. It helped me.
