"Cool API you wanna use there, would be a shame if it doesn't work on half your target systems" - #Microsoft, with the #WinRT PackageManager API.

Fuck you.

#Win32

How?

Type: System.Runtime.InteropServices.COMException
Message:
Stack Trace: at WinRT.ExceptionHelpers.<ThrowExceptionForHR>g__Throw|38_0(Int32 hr)
at …
at Windows.ApplicationModel.StartupTask.GetAsync(String taskId)

Why is StartupTask.GetAsync(id) failing.

And why isn't the exception showing the error code?

Anyone here with #WinRT knowledge?
If I have e.g. com:ComInterface and com4:ComInterface registered, does com4 on supported systems override the com declaration?

Why is #WinRT / WinMD so much more pain than creating the same in regular #MIDL #COM?

Has someone performed any micro benchmarking of COM/WinRT against PInvoke?
I.e. I have a wrapper in WinRT, and call some Win32-function, vs calling the Win32 function directly from C#?

Anyone here got a fancy wrapper struct for COM instances, that allows for dot-method calls, is IDisposable, and works seamlessly with IUnknown**, void**, T**, out IUnknown*, out void*, out T*, and doesn't depend on weird Marshal RCW-behaviors?
Basically C++ smart pointers for COM (like WIL/WinRT com_ptr, com_ref).

#WinRT

Well! I have to say, kudos to the #winrt projection team from microsoft and #dotnet using the winrt api from both #fsharp and #rust is nearly the same

In this case I'm just using the Windows.Security.Cryptography.DataProtection namespace to read a file using the winrt api (I could use bcl/std apis I know) convert it into a stream, use the DataProtection apis to encrypt the file, the encrypted file gets saved as a new file (so I can see it rather than just do it to the same file) and then decrypt that file into a new one which technically is just a copy of the first one but after encryption/decryption :)

Trying out #WinRT APIs for hours just to find out they're only supported in Windows IoT version is my passion 🤪.

Do you think using #fsharp is somewhat niche?
Well... I got you a real niche!
Recording with your camera using #WinRT APIs with

as your window handle provider from F# 😅

I should technically be able to use MAUI or other windows desktop solution (WPF or WinForms) but I figured that If Avalonia (which works wonders with F#) could give me a window handle that's all I needed.

So yeah... any time you feel you think desktop and servers with F# is niche, remember there's a dude trying out WinRT APIs with F# and a cross-platform framework

If you ask me "Why not MAUI"? I'd answer:

I don't know, does it even support F#?
Feel free to poke me with a sample with it I'll happily try it out :)
