[Windows] PlatformImage.FromStream crash

[nor0x]

Description

trying to get an image from the web as an IImage like this:

var imageUrl = "https://source.unsplash.com/random";
var stream = await new HttpClient().GetStreamAsync(imageUrl);
var img = PlatformImage.FromStream(stream);

crashes the app on Windows with the following Exception:

   at System.IO.WindowsRuntimeStreamExtensions.AsRandomAccessStream(Stream stream)
   at Microsoft.Maui.Graphics.Platform.PlatformImage.<>c__DisplayClass18_0.<<FromStream>b__0>d.MoveNext()

Cannot use the specified Stream as a Windows Runtime IRandomAccessStream because this Stream does not support seeking.

Works fine on Android

Verified this issue with Visual Studio 17.10.0 Preview 3 (8.0.20 & 8.0.0-rc.2.9530). Can not repro it with sample project

@kevinxufei how did you test?

I just downloaded the repro project, updated to the latest maui nuget packages and I'm still able to reproduce this:

   at System.IO.WindowsRuntimeStreamExtensions.AsRandomAccessStream(Stream stream)
   at Microsoft.Maui.Graphics.Platform.PlatformImage.<>c__DisplayClass18_0.<<FromStream>b__0>d.MoveNext()
   at Microsoft.Maui.Graphics.Platform.AsyncPump.Run[T](Func`1 asyncMethod)

   at MauiApp1.MainPage.<OnCounterClicked>d__2.MoveNext() in C:\dev\MauiApp1\MauiApp1\MainPage.xaml.cs:line 22

I'm on .NET 8 version 8.0.300-preview.24203.14 and I have referenced the following MAUI packages:

<PackageReference Include="Microsoft.Maui.Controls" Version="8.0.20" />
<PackageReference Include="Microsoft.Maui.Controls.Compatibility" Version="8.0.20" />

updated my repro to 8.0.40. The exception is the same - is this something that even was adressed at all in a recent release @jsuarezruiz ?

Workaround for this issue should be:

https://github.com/dotnet/maui/pull/23626/files#diff-7809b7d3f7611c78ba9e346d0e686e7f564ec68d1c25bc19bee122f9f9f1439dR167-R168

but hopefully #23626 will be merged.
