maui MAUI app crashes on Android in debug mode and has errors in release mode

Description

I am attempting to run the demo app created by Visual Studio when creating a new MAUI .NET 8 project on Android, but I am encountering problems in both debug and release mode. When I run the app in debug mode, it crashes at startup with no useful errors. When I try to compile the app in release mode, I get different errors. I have tried different physical devices and emulators with the same results and have already attempted to reinstall Visual Studio. Can someone suggest additional tests or solutions to help me understand and resolve this problem?

Steps to Reproduce

No response

Link to public reproduction project repository

No response

Version with bug

8.0.3 GA

Is this a regression from previous behavior?

Yes, this used to work in .NET MAUI

Last version that worked well

7.0.101

Affected platforms

Android, I was not able test on other platforms

Affected platform versions

No response

Did you find any workaround?

No response

Relevant log output

When I try to run the app in debug it crashes at startup with no useful errors:

Instead when I try to compile it in release mode I receive these errors:

Thanks for the feedback, but we'll need some info:

Did you try with PublishTrimmed=false??

Error NETSDK1144 Optimizing assemblies for size failed. Optimization can be disabled by setting the PublishTrimmed property to false. TestNet8 C:\Nuget\microsoft.net.illink.tasks\8.0.3\build\Microsoft.NET.ILLink.targets 87

Based on

Cmdline: com.companyname.testnet8 and
C:\Users\Sviluppo2\Desktop\Test\TestNet8\bin\Release\net8.0-android\TestNet8.dll

seems like you have small repro/test project. Would you be so kind and publish it as a public repo or upload it here. Our gurus need to take a look into it.

Thanks.

I already tried with PublishTrimmed=false and with RunAOTCompilation=false and these are the results

set PublishTrimmed as false:

I put here my project but it's only the new project created by visual studio without ayn change, if you need bin or obj folder I can try to upload them but they are too large for this file. TestNet8.zip

Apr 02 '24 07:04 paro-ricc

@paro-ricc

Thanks for the feedback.

Few things:

please try setting RunAOTCompilation to false. Just to see.
bin and obj folders are rarely needed for analysis.
I will check your submitted sample, shortly. Just to finish some daily tasks.

thanks

I have slightly different errors, but AOT related.

No. You do NOT need to upload them. You did everything right.

I copied your csproj but I continue to have the same errors. Could it be a problem in my PC?

Most likely. Something might be messed up. Do you have previews installed?

please, for starters:

post dotnet --list-sdks
post dotnet --list-runtimes
post dotnet --info

then we'll see

Can you upload binlog, please?

dotnet build TestNet8/TestNet8.csproj -f:net8.0-android /bl

If you are not comfortable with CLI this could help:

I just noticed that with your command I don't have any error

My bad. Sorry. That command did not build Release and thus not done any optimizations. Too much work in parallel and then I make mistakes.

Run target will trigger everything:

dotnet build TestNet8/TestNet8.csproj -f:net8.0-android -c:Release -t:run -bl

Another tip - delete bin and obj folders before.

@paro-ricc

Seems like installation issue on your box.

While I go through the logs, can you please try:

dotnet workload repair

If that does not help I usually would do uninstall then install...

dotnet uninstall <LIST>
dotnet install <LIST>

You can get the <LIST> with

dotnet workload list

and yes please report if that helped.

Apr 04 '24 15:04 moljac

I tried dotnet workload repair but didn't work, now i'm trying to uninstall then install, but those commands don't exist; did you mean dotnet workload uninstall and dotnet workload install?

Apr 05 '24 07:04 paro-ricc

I've seen similar behavior with obfuscated assemblies, but I don't see anything in the binlog that would point to something which looks like obfuscated assembly. (I could be missing something).

The piece of information to diagnose this is the exact method for which the exception happens. You can get it by running the trimmer under a debugger. The simplest way is:

Open the binlog with the failure in the MSbuil Binlog viewer
FInd the error (it should point to it on open)
Copy the value of the CommandLineArguments
Paste it into a new file called linker.rsp and put that file into the root of your app (where you run the dotnet run from)
Cut the dotnet.exe ...illink.dll from the begining of the file and paste it into command line (current directory the root of your app)
Append @linker.rsp to the command line and run it
It should fail again - the exact same way
Now run this command under a managed debugger (VS should work just fine) and let it stop on the exception. Once there go to the frame ReadMethodBody(MethodDefinition) and take a look at the value of MethodDefinition it should point you to the method which is having the problem.

Alternatively, you could use https://github.com/vitek-karas/illinkrepro which will package all of the input files for the trimmer into a directory (see the description in the repo). You can then zip it and send it to use to repro here - for this I would advice you use the VS Feedback tool since that will give you the option to share this file "privately with just MS" and then just share the link to the feedback item here.

It should fail again - the exact same way

I managed to reach this point and I can confirm it failed the same exact way

but i don't know how to run a command under a managed debugger as you requested in the last point

Now run this command under a managed debugger (VS should work just fine) and let it stop on the exception. Once there go to the frame ReadMethodBody(MethodDefinition) and take a look at the value of MethodDefinition it should point you to the method which is having the problem.

Could you explain me how to do it?

Meanwhile I'll try your last suggestion; the project is an empty maui app, do you think there might be privacy issues if I put my .zip here?

Alternatively, you could use https://github.com/vitek-karas/illinkrepro which will package all of the input files for the trimmer into a directory (see the description in the repo). You can then zip it and send it to use to repro here - for this I would advice you use the VS Feedback tool since that will give you the option to share this file "privately with just MS" and then just share the link to the feedback item here.

How to debug it with VS: https://devblogs.microsoft.com/visualstudio/how-to-debug-and-profile-any-exe-with-visual-studio/

Open the dotnet.exe path from the command line as a Project in VS. Right click on it in Solution Explorer and select Properties. As arguments specify path/to/illink.dll @linker.rsp and then set the Working Directory to point to the main app directory.

You can also set the Debugger Type to Managed (.NET Core, .NET 5+).

Run the app with F5 - it should stop on the exception. If it doesn't open exception settings (Debug-> Windows -> Exception Settings) and make sure the Common Language Runtime Exception checkmark is checked, not just semi-checked (uncheck and check it again). Run again - now it might stop on some more exception, so if it does and it's not the one you're looking for just F5 over it and keep on running until it hits the problem in question)

thanks, the method GetInstruction(Collection<Instruction> instructions, int offset) in class Mono.Cecil.Cil.CodeReader, got instructions.size with 0. so throw the IndexOfRangeException.

downgrade Microsoft.Maui to 8.0.7 maybe can fix this issue.

Apr 17 '24 06:04 fuxuejun

@vitek-karas here's the exception where the debugger stopped.

Unhandled exception at 0x00007FFC8B7153AC (KernelBase.dll) in dotnet.exe: 0xE0434352 (parameters: 0xFFFFFFFF80131508, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x00007FFC28930000).

Apr 17 '24 07:04 paro-ricc

@fuxuejun - can you please share the callstack or the GetInstruction call?

@paro-ricc - that looks like a native debugger exception - can you please make sure that you set the debugger type to Managed? In either case, could you share the callstack (that should not contain any confidential data as it will be callstack in the illink tool alone).

Apr 17 '24 08:04 vitek-karas

@vitek-karas sorry, I use dnspy to debug the nuget illink dll, callstatck is byte[] arrary, the callstatck is in downstair.

repro.zip I'll also put the repro here; there are no private files

the illink.dll 8.0.2 and 8.0.4 in nuget with maui 8.0.20 will throw this exception. the 8.0.7 version works well.

I tried but I have the same error with all the versions

sorry, i found the real reason is nuget cache file was modified by other program, just clean the nuget cache folder, then restore the nuget, then it works ok.
