  <!--
        This file is used to control the platforms compiled by Visual Studio, and allow for a faster
        build when testing for a single platform. This will also result in better intellisense, as
        the compiler will only load the assemblies for the platform that is being built. You do not
        need to use this when compiling from Visual Studio Code, the command line or other IDEs.

        Instructions:
        1) Copy this file and remove the ".sample" name
        2) Uncomment the single property below for the target you want to build
        3) Make sure to do a Rebuild, so that nuget restores the proper packages for the new target

        Notes:
        - You may optionally close the solution before making changes and reload the solution afterwards. This will avoid Visual Studio
          asking you to reload any projects, it will also ensure that the changes are picked up by Visual Studio, and trigger a restore of
          the packages.
        - You may want to unload the platform heads that you are not going to build for. This will ensure that Visual Studio does not
          try to build them, and will speed up the build process.

Nothing unusual in prism, session looks ok (unless it's reported from separate session).

[xperiandri]

You can try cloning this repo https://github.com/Ecierge/Elmish.Uno/tree/Ecierge And opening either Elmish.Uno.sln or Samples.sln

But in order to experience the problem immediately it is better to replace this line https://github.com/Ecierge/Elmish.Uno/blob/3c09b43ee22297151ee09ae1c463f864adcb6721/src/Elmish.Uno/Elmish.Uno.fsproj#L3 with <TargetFrameworks>$(DotNetVersion)-windows10.0.22621</TargetFrameworks> Use windows10.0.22621 whatever Windows SDK you have installed, it does not matter for the issue to appear

@abonie can I help you somehow? This issue affects our team's performance very-very much ☹️☹️☹️

[abonie]

I unassigned myself - didn't have time to even look into the issue yet :/

I tried out of curiosity, but these repro steps don't do it for me. There are other errors but typechecking seems fine:

[xperiandri]

@majocha what if you have 2 target frameworks? Windows and Desktop or a Windows and plain .NET

[majocha]

@xperiandri I tested with this: <TargetFrameworks>$(DotNetVersion)-windows10.0.22621;$(DotNetVersion)</TargetFrameworks>

F# analysis worked fine from the start. Curiously I had some yellow bars in VS indicating Roslyn (C#) exceptions. Those disappeared after I built the solution properly.

However I did 2 changes, to make it build:

• upgrade UnoToolkitVersion to 6.3.6 here
• uncomment this line

ETA: VS 17.12.3

[xperiandri]

Do you have 1 or 2 frameworks in this combobox (highlighted yellow)?

[xperiandri]

You need to have both to be present for the issue to happen

[majocha]

Yep:

[xperiandri]

Interestingly, this happens for me only when I change a branch in Git

Do you happen to have Transparent Compiler enabled?

[xperiandri]

I enabled only snapshots

[majocha]

Ok I can repro this now with Samples.sln from Elmish.

Edit: Let me look deeper into it, but basically for some projects we never get an item cached in commandLineOptions.

[T-Gro]

Just noticed the full config above - is the OverrideTargetFramework needed here? Also, there is a commented line specific to .fsproj, is that intentional?

[majocha]

Edit: Let me look deeper into it, but basically for some projects we never get an item cached in commandLineOptions.

And after git clean it works again. It seems some combination of built / restored / partially built with some errors puts the solution into a state where CPS just does not report options for Elmish.Uno.fsproj net8.0-windows10.0 but it's intermittent.

[xperiandri]

Framework override used if you want to filter some targets locally. I.e. You want to work with Windows and Android only instead of loading and building all Windows, Android, iOS, MacCatalyst, Wasm, Desktop Uno targets

[xperiandri]

@T-Gro, wich commented line?

[xperiandri]

@majocha Yep, it works after clean but breaks then

[majocha]

This is when it works ok:

When it's broken, commandLineOptions has Count = 6 and the Elmish.Uno windows target is missing from it.

[T-Gro]

@T-Gro, wich commented line?

This: <OverrideTargetFramework Condition="''!='hint: Windows App Sdk (WinUI)' AND '$(MSBuildProjectExtension)'=='.fsproj'">$(DotNetVersion);$(DotNetVersion)-windows10.0.22621</OverrideTargetFramework>-->

[xperiandri]

Ah, at that time, I tried another set of frameworks for F# projects. Not all (Windows, Android, iOS, MacCatalyst, Wasm, Desktop Uno targets), but only Windows and generic (net8.0-windows10.x.x.x;net8.0). But I no longer do that, as the generic target is not suitable for other platforms

[xperiandri]

Now I do only
