Visual Studio Intellisense not showing some classe

问题:

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

What worked for me is unloading and reloading the project

回答2:

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.

回答3:

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.

回答4:

I am using ReSharper. What worked for me:

1. Unload project.
2. ReSharper > Options > Environment > General > Clear caches
3. Close solution.
4. Exit Visual Studio.
5. Restart Visual Studio.
6. Reload project.

回答5:

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.

回答6:

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).

回答7:

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))
