Can't debug or run Xamarin Mac app in Jetbrains Rider IDE

Hello Aurrutia ,

Thank you for contacting Rider Forum and sorry for the delay in the reply. 

Could you please try tweaking the MSBuild version in Settings | Build, Execution, Deployment | Toolset and Build? 

If that does not help, please provide me your .csproj file, reproduce the issue and collect the full log bundle so we could take a closer look at the case? 

Thank you in advance and have a great day!

I tried tweaking the MSBuild version a couple times but still it did not work.  I reproduced the issue and have collected the logs. There isn't a way to attach to this thread so i submitted a request https://rider-support.jetbrains.com/hc/en-us/requests/6019325. You can find the csproj file and logs there. Thank you Anna Morozyuk 

Hello Aurrutia ,

Thank you for your reply. I have checked the logs provided and can state that you have faced a recent bug with ID: 

RIDER-104817 Rider 2023.3.x - Cannot run/debug Xamarin.Mac macOS project

It is going to be fixed in the bugfix 2023.3.4. At the moment, there is no workaround available for this issue. 

Thank you for understanding. Let me know if any further questions remain. 

Anna Morozyuk Thank you.  When is 2023.3.4 expected to be released?

Aurrutia , the bugfix 2023.3.4 is going to be released by the end of next week.

Anna Morozyuk Hi Anna. Is 2023.3.4 released yet? I do not see it available for download on the website. If not, is there an update on when it will be?

Hello Aurrutia ,

At the moment, the bugfix is available. Please update Rider and let me know if the issue persists.

Hi Anna Morozyuk I updated to 2023.3.4 and I still get the same issue.  Can i please get some help with this?

Anna Morozyuk I've attached the logs and csproj file again here on this new request ticket https://rider-support.jetbrains.com/hc/en-us/requests/6158133

Hi Anna Morozyuk . Any updates on this?

Hello Aurrutia,

Sorry for the delay in the reply.

At the moment, we could not neither reproduce the issue, nor find anything useful in the logs. 

Thus, could you please provide me with two more things: 

1. Scree-cast of the issue;

2. Logs with debugger tracing collected the following way: 

• Go to Help | Diagnostic tools | Choose Trace Scenarios 
• Enable the Trace scenario for Debugger;
• Reproduce the issue with the trying debugging the solution
• Collect the full log bundle via Help | Collect Logs and Diagnostic Data, 
• Disable Trace scenarios;
• Attach the resulting log bundle to this ticket or upload it to our server (https://uploads.jetbrains.com/) and share the ID.

Thank you in advance. Looking forward to hearing from you soon. 

Anna Morozyuk I have attached what you requested to this ticket that I still have open https://rider-support.jetbrains.com/hc/en-us/requests/6158133

I was unable to attach any of my demo screen cast videos because the files were too large for your system.

Aurrutia , you may want to drop it to out shared storage and provide the upload ID afterwards:

Thank yo in advance! 

Anna Morozyuk ok. Here is the Upload ID for the screen cast 2024_04_03_25Ef9wocbtwjQH7r2NgiaM

 

Aurrutia ,

Could you please additionally debug another Run Configuration, i.e. for mac in Run > Edit Configurations? And collect logs with trace as well? 

 Go to Help | Diagnostic tools | Choose Trace Scenarios 

• Enable the Trace scenario for Debugger;
• Reproduce the issue with the trying debugging the solution
• Collect the full log bundle via Help | Collect Logs and Diagnostic Data, 
• Disable Trace scenarios;
• Attach the resulting log bundle to this ticket or upload it to our server (https://uploads.jetbrains.com/) and share the ID.

Thank you in advance! 

Anna Morozyuk Not sure I 100% understand. You want me to go to Run > Edit Configurations and then what?  Should i be adding a new config template by clicking Edit configuration templates… and selecting Xamarin.Mac? Even if I do that it says “No projects to run” in the Project: selection field.

Anna Morozyuk Does your team offer support over Zoom or any type of call service? I feel like that would be more efficient

Aurrutia ,

This log might shed light on the issue's case, thus, I'd like to receive it first and then plan further steps. 

Could you please launch a mac project from the Solution Explorer using the mouse right click like it is shown in the screen-shot below?

Please collect logs with trace after debugging this project: 

 Go to Help | Diagnostic tools | Choose Trace Scenarios 

• Enable the Trace scenario for Debugger;
• Reproduce the issue with the trying debugging the solution
• Collect the full log bundle via Help | Collect Logs and Diagnostic Data, 
• Disable Trace scenarios;
• Attach the resulting log bundle to this ticket or upload it to our server (https://uploads.jetbrains.com/) and share the ID.

Thank you in advance! 

Anna Morozyuk Ok. Should this Mac project be a new mac project that i create? Or are you talking about our existing Xamarin.Mac project (the one we are seeing the issue with)? Sorry, still a little confused.

Aurrutia ,

I meant the project you already have.

Looking forward to hearing from you soon.

Anna Morozyuk My trial has run out (great timing). Our team is really interested in using Rider but we want to make sure it works for us first.  Are you able to provide me with a new temporary trial code or something so we can continue to debug this?

Aurrutia ,

The trial key should be sent to your e-mail. Looking forward to getting the logs. 

Anna Morozyuk I got the code. I see this though  after I paste it in and click Activate.  It doesn't work.  It doesn't make sense because we are in April!

Anna Morozyuk I actually see this after clicking activate so it looks like it briefly works. But when i hit continue it just pops back up with the red error message

Hello, 

Was any progress made on this issue? 

I am running into the same problem when trying to run my pre-existing Xamarin project as well from Rider. 
I am getting the same error message when I try to run. The app builds fine though. 

[ERROR] FATAL UNHANDLED EXCEPTION: System.DllNotFoundException: Could not find the runtime library libxammac.dylib

Hello Vanessa ,

Thank you for the update. 

Unfortunately, at the moment, the root cause is not clear. Could you please collect logs with tracing as I wrote above? 

• Enable the Trace scenario for Debugger;
• Reproduce the issue with the trying debugging the Xamarin project
• Collect the full log bundle via Help | Collect Logs and Diagnostic Data, 
• Disable Trace scenarios;
• Attach the resulting log bundle to this ticket or upload it to our server (https://uploads.jetbrains.com/) and share the ID.

Thank you in advance. 

Thank you Anna!
