Refreshing the Auto Complete (Intellisense) Database in Visual Studio

Is it possible to manually refresh Visual Studio 2019 IntelliSense DB for Python?

Is there a way to manually refresh IntelliSense in VS 2019?

I think you cannot get what you want in VS2019 and the question which you ask make sense.

In VS2017 version 15.5 or before, Microsoft team added a manual refresh Intellisense database to improve performance.
But since then, the team has dropped the button for other reasons. You can see it from this document.

However, there are some other communtiy members has raised this issue and Microsoft said they were working on it.

In order to get the attention of Microsoft as soon as possible, I have reported this problem to the DC Forum for you. You can add any comments which contains any detailed info in this link.

Besides, anyone who is interested in this issue will see it and then vote it to draw Microsoft's attention.

While you're waiting, you can only restart the project as multiple times as you described.

SQL Server. How to refresh the intellisense?

Ctrl + Shift + R will refresh Intellisense.

How to automatically refresh the SQL Server Management Studio intellisense cache?

I don't know that there is a way to automatically refresh the cache without manually pressing Ctrl+Shift+R (or equivalent, e.g. the menu). The reason is that when the app talks to the database too much, people complain that it is too chatty (perhaps someone could write a simple add-in that does this - using something like query notifications to indicate something has changed in the metadata views?). You may also want to consider an add-on like SSMS Boost (though with a quick keyword search I see no mention of this functionality on its feature page) or SQL Prompt (but also I don't see any evidence of this functionality in their documentation, only a mention here of an experimental feature).

I believe SQL Server Data Tools does this, but I don't know if you can control the frequency of the refresh. And using that tool may also require a significant shift in how you think about database development.

Why does intellisense and code suggestion stop working when Visual Studio is open?

I spent a lot of time researching the same problem. Some solutions related this bug with some referenced assemblies. Others said that Microsoft.Windows.Design.Extension.dll and .Interactivity.dll should be in the references of the project. But none of these solutions worked for me.

I think it is a bug in Visual Studio 2012, Microsoft has to fix it.
