Serilog Eventlog问题

Question

我有asp.net core 2.0项目。我正在使用Serilog进行日志记录。这是我的项目文件：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>

C＃逻辑

Log.Logger = new LoggerConfiguration()
             .MinimumLevel.ControlledBy(_loggingLevelSwitch)
            //.MinimumLevel.Debug()
            //.MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
            //.MinimumLevel.Override("System", LogEventLevel.Warning)
            //.MinimumLevel.Override("Microsoft.AspNetCore.Authentication", LogEventLevel.Information)
            .Enrich.WithProperty("ApplicationName", _systemConfiguration.ApplicationFriendlyName)
             //.Enrich.FromLogContext()
             .Enrich.WithEnvironmentUserName()
               .Enrich.WithExceptionDetails()
               .Enrich.WithMachineName()
               .Enrich.WithProcessId()
               .Enrich.WithThreadId()
               .WriteTo.ColoredConsole()
            //.WriteTo.File(@"PCI.identityserver4_log.txt")
            .WriteTo.EventLog(GetExecutingAssemblyName(), "Application", restrictedToMinimumLevel: _systemConfiguration.LoggingConfiguration.WindowsEventlogVerbosity)
            //.WriteTo.Console(outputTemplate: "[{Timestamp:HH:mm:ss} {Level}] {SourceContext}{NewLine}{Message:lj}{NewLine}{Exception}{NewLine}", theme: AnsiConsoleTheme.Literate)
            .CreateLogger();

。WriteTo.EventLog（）正在抛出

System.TypeLoadException：'无法加载类型 来自程序集'System，Version = 4.0.0.0的'System.Diagnostics.EventLog'， 文化=中性，PublicKeyToken = b77a5c561934e089'。'

Nuget软件包Serilog.Sinks.EventLog（3.0.47）显示以下警告

使用'.NETFramework，Version = v4.6.1'而不是项目目标框架'.NETCoreApp，Version = v2.0'恢复了包'Serilog.Sinks.EventLog 3.0.47'。该软件包可能与您的项目不完全兼容。

请帮助我解决此问题。

我知道这有点晚了。但是，您使用的Serilog是与.NET core不兼容的。确保已安装Serilog.ASPNetCore软件包。那应该可以解决您的问题。
