Intellisense <Note> still happens sometimes when using Nuget packages referencing System.Runtime.WindowsRuntime

[Thorium]

I've not been able to repro this issue easily in a minimal repo, but sometimes the FSharp intellisense still fails (after PR #9644 which fixed similar issues) with the same <Note>:

The type 'IAsyncOperationWithProgress`2' is required here and is unavailable. You must add a reference to assembly 'Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null'.

This may happen if your project references packages that reference packages like System.Net.Http which references System.Runtime.WindowsRuntime. Even though WindowsRuntime package is referenced only on NetCore 5.0 (aka UAP10), it seems that it's still loaded to VS memory somehow.

Known workarounds

Try to avoid components that reference System.Runtime.WindowsRuntime (with paket why) and try to restrict what target-frameworks are used in loading those components.

Here is a stacktrace of intellisense when failing:

[Thorium]

Maybe a silly question, but wouldn't the intellisense be faster if it would try to load only proper target-framework assemblies instead of all the reference assemblies?

[Thorium]

I found a new workaround for Paket users:
Add framework restrictions to top-level of paket.dependencies, like for example:
frameworks: net461, net472, net48, netstandard2.0, netstandard2.1, netcoreapp2.1, netcoreapp3.1, net5.0, net6.0, net7.0
...and that will remove the unnecessary framework-libraries (like these WindowsRT stuff) totally.
