Visual Studio Intellisense suggestions disappears immediately after coming up

Question

I am using Visual Studio Community and Visual GDB to code and debug STM32 projects.

The problem:

When I type something that is known to Intellisense, (path, variable or anything really), the suggestions come up briefly and then immediately disappear therafter. For that split second I can see that Intellisense has the correct suggestions, but TAB or ENTER does not work since the suggestions disappear very quickly.

Does anyone know how to fix this?

Thank you

Answer 1

You might try to disable any extensions in Visual Studio.

I had the same problem, surfed around and read in some places that disabling extensions would work.

So I disabled them one by one and the problem was gone.

Answer 2

I have the same issue, I noticed that it happens when the suggestion involves the context that is quite long beyond the screen. Here is how it look like:

---

|Function1(xxx,xx,xxxxx,xxx,xx,xxxxxxxxx, xxx) |Function2(xxx,xx) | | | |______________________________| Screen So if it has something like Function1 in that suggestion then it will instantly disappear after popup. The temporary solution is to separate the long function into 2 functions or more. I’m also looking for a better solution that might need some setting in the visual studio and make this long function working.
