Unable to run dotnet core application on Mac using dotnet command, but works under vscode

@danwalmsley commented on Tue Jul 11 2017

Basically I have an application written for netcoreapp2.0

It runs perfectly via vscode debugger with setting

"console": "internalConsole" (I mention this as it may be a clue to what is happening)

If I tell vscode to use external console or…

If I run it through the terminal on mac and do dotnet ./myapp.dll

I starts to load and crashes with

could not load file or assembly System.Text.RegularExpressions, Version=4.0.0.0

How can it be the case it works under vscode terminal but not bash? How can I get more verbose output that could help you guys diagnose the issue?

@steveharter should be able to help out here.

Thanks! I have the feeling, vscode is using an internal console and its environments / paths, etc is correct, when I use bash something is missing ands its not able to resolve assemblies.

@danwalmsley try export COREHOST_TRACE=1 and run again to get verbose output. This will tell you where it is looking for the runtime and related assemblies.

It is possible that the version of System.Text.RegularExpressions that is found is older.

The error message when I run the application normally. It can’t find AvaloniaEdit.dll, which is included (see prev post with dir listing)

Do you know why the error message changed from failing to load System.Text.RegularExpressions to AvaloniaEdit? Does it still work under different vscode settings?

The triggering exception appears to be OmniXaml.LoadException, wrapping a System.IO.FileLoadException for AvaloniaEdit.dll. From the log, that assembly appears to be found by CoreClr at /Users/richard/avalon/AvalonStudio/AvalonStudio/AvalonStudio/bin/Debug/netcoreapp2.0/osx.10.12-x64/AvaloniaEdit.dll.

However I would guess that OmniXaml is doing a custom load of the AvaloniaEdit.dll and is not using the same directory as CoreClr to find that assembly. Perhaps it needs to intercept the assembly resolving events?

Other misc from the log: App base location: /Users/richard/avalon/AvalonStudio/AvalonStudio/AvalonStudio/bin/Debug/netcoreapp2.0/osx.10.12-x64 App location: Users/richard/avalon/AvalonStudio/AvalonStudio/AvalonStudio/bin/Debug/netcoreapp2.0/osx.10.12-x64/AvalonStudio.dll Launch host: /usr/local/share/dotnet/dotnet JIT_PATH: /Users/richard/.nuget/packages/runtime.osx-x64.microsoft.netcore.app/2.0.0-preview2-25407-01/runtimes/osx-x64/native/libclrjit.dylib Probing directory: /Users/richard/.nuget/packages/ with several subdirectories (not complete): lib/netstandard1.1 Avalonia.Direct2D1/0.5.1-build3417-alpha avalonia.direct2d1/0.5.1-build3417-alpha/lib/net45 Avalonia.Gtk3/0.5.1-build3417-alpha avalonia.win32/0.5.1-build3417-alpha/lib/netstandard1.1 Avalonia.Skia.Desktop/0.5.1-build3417-alpha avalonia.skia.desktop/0.5.1-build3417-alpha/lib/netstandard1.3 Avalonia.Xaml.Behaviors/0.5.0 avalonia.xaml.behaviors/0.5.0/lib/netstandard1.1 avalonia/0.5.1-build3417-alpha/lib/netcoreapp1.0/

@steveharter sorry for delay, my colleague with mac is away, so I will come back to you once we have access to mac, to give you more information. Thanks Dan

@steveharter Ok I don’t know why the error message changed, i rebuilt from scratch and the error went back to original one. I have attached a new log file, and linked a youtube video so you can see what is happening.

youtube shows me using the console in vscode to invoke the app, and it working. then me using terminal, and it not working.

thanks for your patience as I have been slow to respond.

From the log, it looks like a previous version of dotnet was installed as it is finding the dotnet executable version 1.0.1 instead of 2.0 preview version. Although I’m not aware of any problems with this (as it should be in “muxer” mode and just forward to the 2.0 preview location) can you please try to replace the dotnet executable with the 2.0 version? At least we can rule that out and then go from there. Thanks.

@steveharter the “A device attached to the system is not functioning” could lead us to figure out the culprit. Could you please run it under dtruss? Like sudo dtruss dotnet ./AvalonStudio.dll That should show syscalls it was making and that means also file open requests. The error makes me think that we might be accessing some weird code path.

Also, keep in mind that the CLI does not support XMAL.

we built our own XAML framework 😉 see here: https://github.com/AvaloniaUI/Avalonia
