Activate auto-complete for C# in Visual Studio 2019

Question

I have the problem, that I get some suggestions for autocompletion (for example, I type "Cons" and I get the suggestion for "Console"), but these can't be applied with the Return-key.

Normally, the suggestion is fully blue, and gets attached, when I press 'enter', but for some time now, the suggestion has a blue border and pressing 'enter' results in a new line. Where can I change these settings, so IntelliSense completes the words again, while I write them? I already tried the IntelliSense-Settings in the C#-options, but these settings didn't change anything

Doesn't the "TAB" button provide the functionality you need? – Ferro

Sure, but before, I didn't need the Tab-Button. I'm used to the auto-autocomplete – Catholicon

Answer 1

There are 2 different autocomplete modus in Visual Studio, suggestion mode has the behavior you describe. Suggestion and standard, explained here. Press CTRL-ATL-SPACE to toggle between these modes.

Answer 2

You likely inadvertently used the keyboard shortcut to toggle completion mode. You can correct it with the same shortcut or in the menu it's Edit -> InteliSense -> Toggle Completion Mode

In my experience, "Toggle Completion Mode" name changed into

Edit -> InteliSense -> "Switch between automatic and tab-only Intellisense completion"
