Fsharp: VS2019 Preview 3.0 F1 help poor with F#

[vsfeedback]

VSF_TYPE_MARKDOWNAccessing help using F1 is poor when using F#. Sometimes it works but for types such as Result (Microsoft.FSharp.Core.Result) it doesn't work. Other examples include:

MailboxProcessor.PostAndReply
'match' keyword
'with' keyword

Yet oddly other keywords like 'function' does go to a page with info about keywords even if not specifically the 'function' keyword.

I'm not sure if this is an issue in the tools. It may be primarily due to not having an FSharp.Core API reference. So any types or functions added after F# 4.1 wouldn't be recognized.

However, match and with should certainly work since they should point to the keyword reference in the .NET conceptual docs. Perhaps the keywords registered with the docs system aren't fully updated. @mairaw do you know where I could do that?

Do you know what's the query URL being sent to those topics?

You can add f1_keywords metadata to associate keywords with a certain topic:
https://github.com/dotnet/docs/search?q=f1_keywords&unscoped_q=f1_keywords

@dendeli-msft used to be the F1 PM. Not sure if he still is or not.

@mairaw It's the help context service : https://github.com/Microsoft/visualfsharp/blob/master/vsintegration/src/FSharp.Editor/Commands/HelpContextService.fs

We will check it out tomorrow.

I just checked with preview 4.1, _match_ and _with_ now go to the keywords help page. But PostAndAsyncReply still goes to just the Visual Studio Documentation home page.

Pressing F1 on List.reduce in a fsx will open https://msdn.microsoft.com/visualfsharpdocs/conceptual/list.reduce%5b%27t%5d-function-%5bfsharp%5d which shows

Sorry, this page is unavailable. Please try again later.

Using VS2019 Community Preview v16.6.0 Preview 2.0 with Visual F# Tools 10.9.1.0 for F# 4.7.

Closing this one out. all F# keywoards will now go to the correct site, which was missing a lot of keywords in the documentation metadata. That should be resolved now when the site goes live in a day (might be live now?)

Separately, the F1 help problems with FSharp.Core constructs is due to an error in redirects for the MSDN reference. This one is currently being investigated but once resolved it will work as usual.
