Description
Type: Bug
Apologies if this is filed with the wrong project. Originally filed with onnxruntime but it was referred to VSCode. Now referred to an extension project. Seems plausible it's a dotnet runtime problem too.
Problem
With a dotnet MAUI project targeting net9.0-maccatalyst using onnxruntime (nuget), the attached debugger can sometimes crash if you set a break point in a function which calls GetTensorDataAsSpan. Even if the break point occurs before that method is evaluated.
It will crash with
The target process exited with code 0 (0x00000000) while evaluating the function 'System.SpanDebugView<T>.SpanDebugView'.
If no break point is set, the code will produce results as expected.
On VSCode windows, if we switch the target framework to net9.0-windows and attempt to debug at the same location, the app will NOT crash.
This problem still exists on the VSCode 1.102 insiders build with only 4 extensions installed (C#, C# Dev Kit, .NET MAUI, .NET Install Tool)
A repo containing some minimal code to reproduce the issue is available at:
https://github.com/tuanchien/spandebugview-vscode-mac-onnxruntime-issue
Set the break point, run the app with the debugger attached, and click the button in the app to trigger the crash.
If you copy and paste the contents of RunOnnxStuff into OnCounterClicked instead, and set a break point inside there, then it does not appear to crash.
