Description

I am trying to just publish the base code when creating a project using dotnet new api --aot -o MyFirstAotWebApi && cd MyFirstAotWebApi

the program runs fine in debug mode then I just do a dotnet publish and get this error MyFirstAotWebApi -> C:\Program Files\no\MyFirstAotWebApi\bin\Release\net8.0\win-x64\MyFirstAotWebApi.dll Generating native code C:\Users\M31926.nuget\packages\microsoft.dotnet.ilcompiler\8.0.0-preview.6.23329.7\build\Microsoft.NETCore.Native .targets(290,5): error MSB3073: The command ""C:\Users\M31926.nuget\packages\runtime.win-x64.microsoft.dotnet.ilcompiler\8.0.0-preview.6.23329.7\tools\ilc" @"obj\Release\net8.0\win-x64\native\MyFirstAotWebApi.ilc.rsp"" exited with code -2147483645.

@jdurnil, this is a known issue that we are working towards fixing. NativeAOTapplications build prior to this PR is susceptible to crashes when a client turns on machine wide tracing while using an impacted NativeAOTapplication. Unfortunately, ILC, the ILCompilertool, is a NativeAOTapplication that shows this problem. We are working towards updating ilc.

A common pattern for this issue: If you are debugging VS on a separate process (breakpoint on a HelloWorld for example) in the same machine, and then uses an impacted NativeAOTapplication (ILC gets used when you invoke dotnet publish). VS in this scenario, will send a request to the affected NativeAOT to turn on tracing, which will cause the problem you see in ILC.

A workaround for that scenario would be to stop debugging VS until the application is published.

Sorry for the inconvenience that this problem caused you.

hello i was not debugging the app during publish i was getting this message with the app completely stopped. What fixed this issue was to do a dotnet restore on the sample project then it built.

Glad that you got unblocked! Let me know if you run into the issue again, and the state of the other programs in the machine. The issue I mentioned above where it impacts ILC can happen when a machine wide tracing is enabled (ETW is turned on machine-wide for example).

This is fixed in .NET 8 release. Thank you for reporting it!
