Microsoft.EntityFrameworkCore.Sqlite 7 crash on iOS #28773

RobertoGFilho · 2022-08-18T11:03:24Z

EfCore 7 crash on iOS MAUI app. Please you can reproduce this erro on this demo : https://github.com/RobertoGFilho/EFCore

Windows ok
Android ok
iOS crash

Visual studio 17.3.1
Include="Microsoft.EntityFrameworkCore.Sqlite" Version="7.0.0-preview.7.22376.2"

eerhardt · 2022-08-18T23:42:07Z

I don't believe this is a NullabilityInfoContextSupport issue. When I ran your app I see the following exception being thrown:

RobertoGFilho · 2022-08-19T12:18:28Z

@eerhardt thanks for you attention!

I'm using Visual Studio 17.3.1 for Windows 11 and real device iPhone 7plus with hotrestart. Only iOS this error happen! I have already worked with EFCore 3.1 and Xamarin for three plataforms and works well.

On Xamarin configuration iOS is:

    public override bool FinishedLaunching(UIApplication app, NSDictionary options)
    {
        SQLitePCL.Batteries_V2.Init();
        global::Xamarin.Forms.Forms.Init();

        var libPath = Path.Combine(
            System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments),
            "..", "Library", "data");

        if (!Directory.Exists(libPath))
        {
            Directory.CreateDirectory(libPath);
        }

        var dbPath = Path.Combine(libPath, "core.sqlite");
        LoadApplication(new App(dbPath));
        return base.FinishedLaunching(app, options);
    }

let me show what is happen on MAUI:

2022_08_19_09_02_50.mp4

I've already add : NullabilityInfoContextSupport = true on project file but it doesn't work

do you have any idea?

eerhardt · 2022-08-19T16:22:42Z

Can you list what version of dotnet and the MAUI workload you are using?

dotnet --info
dotnet workload list

I'm using a mac with 6.0.400 of the dotnet SDK and 6.0.486/6.0.400 of the maui workload.

When running the app on an iPad simulator in Debug mode, the app works fine. When running with -c Release, I get the above exception.

RobertoGFilho · 2022-08-19T20:39:34Z

@eerhardt

I'm using 6.0.8

I'm using a real device "iPhone 7" plus iSO version 15 .. in debug mode .. and hotrestar enable

eerhardt · 2022-08-19T20:44:22Z

What is the output of dotnet workload list?

eerhardt · 2022-08-24T20:33:25Z

Unfortunately, I can't repro this behavior.

If I launch the app on a physical phone using VS for Mac, it works correctly. I don't see an exception being thrown.

I'm not able to deploy any Maui app to a physical phone from VS on Windows for some reason, and I spent too much time trying to get it to work. I've given up.

My suggestions for debugging this would be to get a binlog of the build and inspect the ILLink task to see what parameters are getting passed to the linker. I don't know why these would be different for iOS vs. Android. Maybe something on your machine is telling it to use different settings.

If a binlog doesn't help, inspecting the .dlls in something like ILSpy may help give a clue. Look for the code using this switch:

https://github.com/dotnet/runtime/blob/e71a9583b4d6c9bd97edd87cda7f98f232f63530/src/libraries/System.Private.CoreLib/src/System/Reflection/NullabilityInfoContext.cs#L20-L21

eerhardt · 2022-08-24T22:11:14Z

Another thing to look for is in the "Build" output (on a fresh build/install), look for the string System.Reflection.NullabilityInfoContext.IsSupported. This should be set to true. If you see it set to false, that's the issue.

Here's a snippet of my build output:

hey @eerhardt ! something very crazy is happen! When I use iOS emulator error disappear, but if i try real device "iPhone 7 Plus" happens error . see:

2022_08_25_09_10_06.mp4

RobertoGFilho · 2022-08-25T12:13:37Z

I have tryed to change : System.Reflection.NullabilityInfoContext.IsSupported = true or false.. but error happens

eerhardt · 2022-08-25T14:40:49Z

but if i try real device "iPhone 7 Plus" happens error .

I've run the EFCore app both from VS for Mac preview on my mac, and from VS for Windows paired with my mac, to a physical iPhone 6S and can't repro this behavior.

Can you try running the app on a different development machine? My guess is that there is something specific about your dev machine that is causing this.

eerhardt · 2022-08-25T14:44:12Z

One idea to try to figure this out:

Delete the app from the physical device. and "Clean" the project. Delete the bin and obj folders to ensure everything is clean.
Follow the steps in https://docs.microsoft.com/en-us/visualstudio/ide/msbuild-logs?view=vs-2022#create-a-binary-msbuild-log-by-using-the-project-system-tools-extension to get a binlog of the build that happens when you deploy to the physical phone.
Attach the binlogs here.

The only thing I can guess is that somehow the System.Reflection.NullabilityInfoContext.IsSupported switch is getting set to false by something, but I'm not sure what. The binlog would tell us who/what is setting it.

RobertoGFilho · 2022-09-05T13:32:09Z

hi @eerhardt same error here on iPhone 6S Plus and 7Plus, on real device

eerhardt · 2022-09-06T15:38:32Z

@RobertoGFilho - did you try the above to get a binlog?

RobertoGFilho · 2022-09-10T22:14:06Z

hi folks!
the trouble is string properties on Model! see:

WORKS:

public class Person : ObservableObject
{
[Key]
public Guid Id { get; set; }
public int Age { get; set; }
//public string Name { get; set; }
}

DOESN'T WORK

public class Person : ObservableObject
{
[Key]
public Guid Id { get; set; }
public int Age { get; set; }
public string Name { get; set; }
}

ErikEJ · 2022-09-11T06:08:15Z

What is ObservableObject?

RobertoGFilho · 2022-09-12T11:22:29Z

hi @ErikEJ ,

ObservableObject is from MVVMHelpers, you can remove this, but the same error will show up! This error happen only string properties on Model. Only iOS plataform.

Please you can reproduce this erro on this demo : https://github.com/RobertoGFilho/EFCore

Hi @eerhardt !

I have done in different machine, the same error shows up!

eerhardt · 2022-09-22T15:04:20Z

Are you able to get a binlog? See #28773 (comment)

RobertoGFilho · 2022-09-24T16:32:23Z

Hi @eerhardt binlog files are bellow:

binlog files.zip

eerhardt · 2022-09-26T17:56:08Z

Hmm, unfortunately those logs don't contain much information. One thing I was able to confirm was that NullabilityInfoContextSupport was getting set to true. But I wasn't able to see any compiler or linker steps happen in the logs.

Did you delete the bin and obj folders to ensure everything is clean before capturing the logs?

RobertoGFilho · 2022-09-26T20:28:01Z

Hi @eerhardt

this binlog wore created after: delete the bin and obj folders to ensure everything is clean.
binlog.zip

the problem is when we have a string property on Model. if i remove this property everythings works see:

this error shows up only iOS.. Android and Windows, it's ok

eerhardt · 2022-09-26T21:01:41Z

I don't see why NullabilityInfoContextSupport=true is not getting flown to the final app. Maybe there is something in the iOS tooling that doing this? @rolfbjarne do you have any ideas? In the attached binlogs, NullabilityInfoContextSupport is set to true. However, at runtime, the exception @RobertoGFilho is getting leads me to believe it is not being set to true:

[0:] An error occurred: 'NullabilityInfoContext is not supported in the current application because 'System.Reflection.NullabilityInfoContext.IsSupported' is set to false.

rolfbjarne · 2022-09-26T21:15:58Z

@RobertoGFilho just in order to narrow things down: do you get the same behavior if you use Visual Studio for Mac (on the Mac)?

RobertoGFilho · 2022-09-27T11:54:09Z

hi @rolfbjarne !

I just work on Visual Studio for Windows!

i have shared this demo : https://github.com/RobertoGFilho/EFCore

rolfbjarne · 2022-09-27T14:39:41Z

We set NullabilityInfoContextSupport to false by default:

https://github.com/xamarin/xamarin-macios/blob/b6cdde42807c6ed5c5fedf471feea0ce4441e584/dotnet/targets/Xamarin.Shared.Sdk.targets#L135

and the test project does not set NullabilityInfoContextSupport at all.

@RobertoGFilho can you try adding this to your project:

<PropertyGroup>
    <NullabilityInfoContextSupport>true</NullabilityInfoContextSupport>
</PropertyGroup>

and see if that works?

eerhardt · 2022-09-27T14:55:55Z

@rolfbjarne - the Microsoft.EntityFrameworkCore NuGet package sets <NullabilityInfoContextSupport>true</NullabilityInfoContextSupport> in its buildTransitive folder. See #27474.

efcore/src/EFCore/buildTransitive/net6.0/Microsoft.EntityFrameworkCore.props

Lines 3 to 7 in 767bc93

    
               <!-- 
        
                    MAUI (and other size-conscient profiles) trim the nullability attributes, causing the EF Core NRT support to break. 
        
                    This prevents the attributes from being trimmed. 
        
               --> 
        
               <NullabilityInfoContextSupport>true</NullabilityInfoContextSupport>

RobertoGFilho · 2022-09-27T16:55:32Z

@rolfbjarne, @eerhardt i have already tryed , but it doesn't work

rolfbjarne · 2022-09-30T13:34:12Z

The test project from the initial description works fine when I run it on a Mac.

The two binlogs (#28773 (comment), #28773 (comment)) come from a build that wasn't connected to the Mac, and thus only a very simple build was done.

@RobertoGFilho, please connect to a mac, build again and get the binlog, or try directly on the Mac (using Visual Studio for Mac) to see if that works for you.

RobertoGFilho · 2022-10-02T00:55:59Z

hi @rolfbjarne @eerhardt binlogs connected to a mac: binlog.zip

@RobertoGFilho those builds are still not connected to a mac.

@rolfbjarne, @ajcvickers @ErikEJ @jsuarezruiz @eerhardt @Eilon @mattleibow i connected to a MAC, but my envioment doesn't use MAC to build a app. See:

My Envioroment:

Windows 11;
Visual Studio 2022 for Windows 11;
Devices : Iphone 7 Plus and Iphone 6 plus;

Thecnologies:

Hot Restart;
Hot Reload;

I understand that you test on MAC is ok, But the problem here is working on Windows without a MAC. I've been working this way with Xamarin Forms and EF Core 3.1 without problem. But when i started working MAUI and EF 7.xx i not able to work on iOS, because string property on model trigger this error.

public class Person
{
[Key]
public Guid Id { get; set; }
public int Age { get; set; }
public string Name { get; set; }
}

On Android and Windows works perfectly.

Conclusion
We need to fix this on Windows environment, because will impact many developers that want to work with MAUI and EF 7.xxx.

This is unlikely to be a problem in EFCore if it only occurs in certain build environments, so I'm moving this issue.

This issue was moved to xamarin/xamarin-macios#16228

I don't believe this is a NullabilityInfoContextSupport issue. When I ran your app I see the following exception being thrown:

this is can be worked around this way: https://stackoverflow.com/a/74786481/7149454
