EF Bundle crash with 7.0

[begerard]

Description When I execute (both localy and on the CD) the "efbundle.exe" generated by entity framework with the new version of serilog-astpnetcore (7.0 instead of 6.1), I have this error:

Host terminated unexpectedly System.InvalidOperationException: No Serilog:Using configuration section is defined and no Serilog assemblies were found. This is most likely because the application is published as single-file. Either add a Serilog:Using section or explicitly specify assemblies that contains sinks and other types through the reader options. For example: var options = new ConfigurationReaderOptions(typeof(ConsoleLoggerConfigurationExtensions).Assembly, typeof(SerilogExpression).Assembly); new LoggerConfiguration().ReadFrom.Configuration(configuration, options); at Serilog.Settings.Configuration.ConfigurationReader.LoadConfigurationAssemblies(IConfiguration section, AssemblyFinder assemblyFinder) at Serilog.Settings.Configuration.ConfigurationReader..ctor(IConfiguration configSection, AssemblyFinder assemblyFinder, ConfigurationReaderOptions readerOptions, IConfiguration configuration) at Serilog.ConfigurationLoggerConfigurationExtensions.GetConfigurationReader(IConfiguration configuration, ConfigurationReaderOptions readerOptions, DependencyContext dependencyContext) at Serilog.ConfigurationLoggerConfigurationExtensions.Configuration(LoggerSettingsConfiguration settingConfiguration, IConfiguration configuration, ConfigurationReaderOptions readerOptions) at MyProduct.WebAPI.Program.<>c.

For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728

The application itself works perfectly, only the bundle crash on startup. When I revert the update, it works again for the bundle.

Reproduction Here the Serilog configuration in Program.cs:

public static void Main(string[] args)
{
    Log.Logger = new LoggerConfiguration()
        .WriteTo.Console()
        .CreateBootstrapLogger();

    try
    {
        var builder = WebApplication.CreateBuilder(args);

        builder.Host.UseSerilog((context, services, configuration) => configuration
                .ReadFrom.Configuration(context.Configuration));

        AddServices(builder.Services, builder.Configuration);

        var app = builder.Build();

        Configure(app);

        Serilog.Debugging.SelfLog.Enable(Console.Error);
        Log.Information("WebAPI started successfully");

        app.Run();
    }
    catch (Exception ex) { Log.Fatal(ex, "Host terminated unexpectedly"); }
    finally { Log.CloseAndFlush(); }
}

The configuration in appsettings.json:

  "Serilog": {
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "Microsoft.EntityFrameworkCore": "Warning"
      }
    },
    "WriteTo": [
      {
        "Name": "Async",
        "Args": {
          "configure": [
            {
              "Name": "File",
              "Args": {
                "path": "D:\\Temp\\Logs\\API.txt",
                "rollingInterval": "Day"
              }
            }
          ]
        }
      }
    ]
  }

Expected behavior I don't know how the EF bundle works internaly, it may be a bit strange around the loading of the appsettings but eventually it doesn't really need the complex configuration from the appsettings (files + ES server), so even a silent error (which may be how it works in 6.1) is ok for me.

Relevant package, tooling and runtime versions I use .Net 7.0 and these serilog packages:

<PackageReference Include="Serilog.AspNetCore" Version="7.0.0" />
<PackageReference Include="Serilog.Sinks.Async" Version="1.5.0" />
<PackageReference Include="Serilog.Sinks.Elasticsearch" Version="9.0.0" />

A test without them still give me a crash for the bundle.

I managed to solve this copying the efbundle.exe file to the /bin/Release directory. It's a workaround and maybe there is a better solution. Hope this help. Greets.

[begerard]

Oh, so it's path related? Good to know thanks.

I have found another work around, excluding Serilog code from executing during bundle execution thanks to the EF.IsDesignTime static property. It is set at true by the bundle.

This appears to be an EF problem rather than one specific to this project.
