Method 2: Disabling Intellisense for a specific file or project

Step 1:

Press the Windows + R keys simultaneously to open the run dialog box.

Step 2:

Type “regedit” and press Enter to open the Registry Editor.

Step 3:

Navigate to HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\16.0_XXXXX\Text Editor.

Step 4:

Right-click on the Text Editor folder and select New > DWORD (32-bit) Value.

Step 5:

Name the new DWORD as “DisableIntellisense”.

Step 6:
