@chenyuAC you should be able to control inlay hints via a language specific setting. For example in your settings.json you can put

"[aspnetcorerazor]": {
    "editor.inlayHints.enabled": "off"
}

which should turn off inlay hints just for Razor files.

However Razor currently does not have options for how the hints are displayed (like the ones in your screenshot) and does not appear to respect the settings for C# in C# blocks either.

[davidwengier]

Razor is a little stuck here between the IDE that has an inlay hints option, and C# which has its own that default to off (the "show for types" and "show for parameters" at least). If we honoured the C# settings then users hit the hotkey and "nothing happens." So we assume that if the client asks for inlay hints, it's because the user wants to see inlay hints, based on either the setting or the hotkey.

Having said that, we could probably try to do something a little better here, and try to honour the other settings at least, or maybe don't override the type and parameter settings if at least one of them is set.

For the most part though, the setting @dibarbet posted above is the way to go.
