Is there any way to disable intellisense for a specific project / namespace / whatever?

Question

Is there any way to do this at any level other than disabling intellisense in all of Visual Studio? Just wanted to confirm/deny a suspicion about its performance in some of our overly giant projects/solutions while keeping it in other areas that we actually care about.

Just FYI, I have a C# class converted/ported from legacy code in a different language which has 7424 members and 51097 lines long. Visual Studio is generally slow doing stuff in that code file but hitting its intellisense is still pretty fast. – Revell

Answer 1

AFAIK there's no way to selectively disable Intellisense. Try disabling it completely and see if that would make a big difference.

You can manually mark your members/class using the EditorBrowsable attribute though I can't say for certain how exactly Visual Studio implements/handles that (it may still do a lot of code analysis just to decide not to show it) – Revell

it's now the end of 2020, almost 8 years from your answer. Is there still no way to do this? – Cabbala

Answer 2

I have noticed a slow down in Visual Studio on my work machine with several VS extensions installed like Spell Checker. Disabling them helped.

Answer 3

you can tell visual studio to ignore certain files by adding to your .editorconfig file. You add the wildcard to match your files and then turn off certain codes. e.g.

#these files are auto generated so I do not want to change them to fix intellisense messages
dotnet_diagnostic.CA1050.severity = none
dotnet_diagnostic.IDE1006.severity = none
