NETSDK1144: Optimizing assemblies for size failed .NET 7

[Clive321A]

I have upgraded a Blazor client app from .net 6 to .net 7 and I'm getting this while building a container image

Error NETSDK1144: Optimizing assemblies for size failed. Optimization can be disabled by setting the PublishTrimmed property to false.

I am using this in my DockerFile FROM mcr.microsoft.com/dotnet/sdk:7.0 AS base

Adding PublishTrimmed false PublishTrimmed

to the blazor client project file does "fix" the issue, but im not really sure what the actual issue is? https://learn.microsoft.com/en-us/dotnet/core/tools/sdk-errors/ Refers to the error, with no information.

Could you share any details (e.g. stack trace) of what failed?

[Clive321A]

Hi, I cant see any stack trace I just get that error when doing a docker-compose --build this seems to be as much as I can see the --verbose option doesnt work with a --build

137 is usually the exit status when a process is terminated by SIGKILL, for example when it runs out of memory. From a quick search I am seeing many issues about other tools failing with status 137 when run in a container, so I suspect there's not enough memory available to your container.

If that's correct, it would be nice for this to show up as an OutOfMemoryException instead, but I don't know enough about OOM hardening in .NET. It would be interesting to experiment with a repro if you are able to share anything.

[Clive321A]

Excellent, that's exactly what it was thanks, I bumped the memory in docker and it builds now with PublishTrimmed on. Unfortunately I dont have a demo repo, ill see if I can create one if I get some time this week. thanks again

@CliveBennett out of curiosity, what was the limit before?

[Clive321A]

I went from 2GB to 6GB, (I have 4 .net 6 apps and 2 MySQL db's applications running in Docker).

(Just for local development)

I have the same issue when building xamarin android app using .net7. It works fine when build using .net6. Issue exists only in Release mode with linker configured to link sdk assemblies only.

I have attached 2 solutions, one with .net6 global.json compiles. The one with .net7 global.json fails on the error above.

Interesting observation is that if I add class that inherit from Activity in root namespace:

using Android.Runtime;
using Core;
using MvvmCross.Platforms.Android.Views;

namespace AndroidApp1;

public class T : Activity
{

}

[Application]
public class MainApplication : MvxAndroidApplication<Setup, App>
{
    public MainApplication(IntPtr javaReference, JniHandleOwnership transfer) : base(javaReference,
        transfer)
    {
    }

    public override void OnCreate()
    {
        base.OnCreate();

        //CrossCurrentActivity.Current.Init(this);
    }
}

Build works fine.

@jmalczak I think your issue is different, the original issue reported here is about OOM situation. Your issue looks like duplicate of #3112.
