This channel is for hacking on Xamarin.iOS and Mac, not use, and I know nothing about CEF but I will note that I’ve heard from a very experienced fellow engineer that embedding CEF is a complete nightmare to get right

If you set the environmental variables MONO_LOG_LEVEL=debug MONO_LOG_MASK=dll you should see spam on what mono is looking for that may be useful

Hello folks, we have been relying on a cool bridge to bring the Xamarin team with the open source community going, but that might be coming to an end.
I have created a Discord server to discuss the internal evolution of Mono and .NET

On my macOS Catalina MacBook Pro, I am using Xcode 11.5 for some personal Swift projects, but using Xamarin.iOS, .Android, and Xamarin.Mac in Visual Studio for Mac 8.6.5 for C# projects for my job, both on the same machine. If I upgrade to Xcode 12 beta 2 so I can try out some new stuff with Swift (independent of C#), will it break my ability to get work done in C#/Xamarin/VS for Mac? targeting iOS <= 13, stuff that currently works fine? (I understand that iOS 14 and Big Sur support are coming to Xamarin later in the summer/early fall. I don't expect to need that stuff for C# this summer, just Swift. And I absolutely need existing/older C# stuff to continue to work this summer, on the same machine with a single installation of Xcode.) Is it safe to upgrade? (acknowledging that there may be Xcode bugs on Apple's end)

Julien Pelc you should be able to have both of the xcode installed in you machine and swich between them using xcode-select. Should not be an issue. We work that way in the team with several installations. Just leave stable in /Applications/Xcode.app and install the beta via the delveloper portal in a diff path

I have a colleague which is seeing some crashes in RayGun with only this information:

NSInvalidArgumentException: *** -streamStatus only defined for abstract class. Define -[System_Net_Http_NSUrlSessionHandler_WrappedNSInputStream streamStatus]!

. Has any of you seen anything like that before?

I've looked at the NSUrlSessionHandler code and can't really see there should be any problem with WrappedNSInputStream in there

thanks for the advice, these logs helped me solve my issue. another question - If i create a NSWindow in a .dynlib that i have p/invoked from main(); and use a callback to give its handle back to xam.mac - am i able somehow dereference this handle to a NSWindow somehow and work with it (ie resize, fullscreent etc)? ie. looking at the api doco i assume this function could help me NSWindow.fromWindowRef(Int.Ptr) but i havnt been able to get it working...?

Rolf Bjarne Kvinge

@rolfbjarne

Use (NSWindow) ObjCRuntime.GetNSObject (ptr)

strike that

Use (NSWindow) ObjCRuntime.Runtime.GetNSObject (ptr)

captainjono

@captainjono

thats returning null for me... seems from the doco it says "if a managed object exists". this window was created in objective-C land in the .dynlib

Rolf Bjarne Kvinge

@rolfbjarne

it'll create the managed NSWindow instance if it doesn't already exist

unless ptr == IntPtr.Zero, in which case it'll return null

captainjono

@captainjono

ok thanks for this info- i didnt know if what i was trying todo was legal. the handle i am passing definitely looks valid in the debugger - this is the callback code

i'll keep hacking at it.

captainjono

@captainjono

was using tryget not get! and now its returned a nswindow correctly. i then do mainWin.InvokeOnMainThread(() => mainWin.ToggleFullScreen()) which throws a UI Consistancy error..? i tried multiple ways to invoke, nothing seems to come off?

Rolf Bjarne Kvinge

@rolfbjarne

did you call NSApplication.Init ()?

captainjono

@captainjono

yeh i did - but i am doing it a little later in the app bootstrapper to allow CEF to startup correctly if needs be (its a multi-process architecture that executes the host process multiple times with different commandline args and can timeout if not snappy). Could that effect Init()?

It seems like its on the correct thread to me; im doing the work in the create handler, and if i throw at that point,I can see the .dynlib createWindow in the stack. Cef has its own methods to call on the UI thread, could also try them.

captainjono

@captainjono

If i inspect the window variable in the debugger, the debugger crashes out with the same error. I can see the correct window title on a prop before it crashes, though so it feels like its connected properly to the underling api / mac window handle on some level.

captainjono

@captainjono

So i went ahead and integrated eto.forms where i was trying to hook into the window handling as i required it for other aspects of the application and have gotten it setup to the point where i can use its UI.Invoke methods to get my calls onto the right thread. i'll step through the source code and see how its achieving the integration, I want to understand the mechanics of whats going on here.

Rolf Bjarne Kvinge

@rolfbjarne

as long as the managed NSApplication.Init () method is called before you do anything else in managed code, you should be fine

Matheus Dadalto

@mthdadalto

Anyone has any idea of how to disable this from mac/win-xamarin?

 touch ~/.mtouch-launch-with-lldb
/
You must now execute:
lldb -s /tmp/mtouch-lldb-prep-cmds

Rolf Bjarne Kvinge

@rolfbjarne

execute rm ~/.mtouch-launch-with-lldb from a terminal

on the mac

Matheus Dadalto

how can I fix this?

/Users/fmoraes/Projects/TestApp/TestApp.Mac/TestApp.Mac.csproj(101,11): error MSB4226: The imported project "/Library/Frameworks/Mono.framework/Versions/6.12.0/lib/mono/xbuild/Xamarin/Mac/Xamarin.Mac.CSharp.targets" was not found.

nm, reinstalling Xamarin.Mac fixed it

Knock knock, anyone home? Is it safe to update XCode to 12.2 (released yesterday)?

Julio César Rocha

@JunielKatarn

This forum has moved to Discord.

That said, yes. I used 12.2 yesterday for my XF project.

Thanks @JunielKatarn. What is the best channel to use in Discord? I posted to #xamarin and didn't get a response.

Hey. Any tips for getting the DeviceAgent app to install along with our Xamarin app on physical phones? We're connecting to an already installed app.

Hello! Does anybody get strange behaviour when referenced project dll is not copied to bin folder in Release mode?

Dmitry

@helviett

What should I do with that?
error MM5312: pkg-config failed with an error code '1'

It doesn't make any sense.

And what build system does Visual Studio For Mac uses? Vstool, msbuild?

Dmitry

@helviett

What's the difference between launching app with open -a /path/to/app and double-clicking app icon?

Our command line tool is unable to find anything it wants when just double clicking app icon.
