Visual Studio Intellisense not showing some classe

Question

My Visual Studio is not showing a lot of the available classes in the IntelliSense auto-complete. For example, a project I'm working on has a reference to the Microsoft.Xna.Framework namespace, yet even after adding the using statement using Microsoft.Xna.Framework in a file, IntelliSense is unable to recognize classes like Texture2D and Rectangle. I can still type them in, however, without getting a compiler error. Any idea what's happening?

The IntelliSense detects standard libraries like System.Diagnostics but not any external ones.

It is not a NameSpace conflict issue because classes within the current namespace are also missing from the IntelliSense.

I have tried:

• Restarting Visual Studio (With and without closing tabs)
• Deleting the contents of %LocalAppData%\Microsoft\VisualStudio\14.0\ComponentCacheModel folder
• Resetting import and export settings

Answer 1

OK so probably not the best solution but it works. I reinstalled Visual Studio and the problem was fixed. Also, it hasn't shown up since (this happened about 3 months ago).

Answer 2

Do you have ReSharper or any other plugins installed? There sounds like a similar issue/solution here. It may be third-party plugins at play depending on what add-ons you have.

Answer 3

another dumb solution))) Determine which classes/namespaces are not showing up. Then go to that project where they are. In that project pick any .cs file copy its contents, then delete that file and create again))

Answer 4

Try saving and reloading the files. I don't know why it happens, but it happens to my work laptop occasionally, typically reopening the source file resolves it.

Answer 5

If unloading/reloading the project doesn't work, try deleting the .suo file found in the SolutionName/.vs/ folder. The .vs folder is an auto-created, hidden folder so you will have to show hidden folders in order to see it.

Answer 6

What worked for me is unloading and reloading the project
