问题描述
我刚刚将我的视觉工作室更新为Preview 4，并将所有软件包从Core 2.0 Preview 1 Final更新为Core 2.0 Preview 2 Final。以下是我的 csproj 文件，全部升级后。

以下是原始异常详细信息。
System.MissingMethodException：找不到方法： Microsoft.Extensions.Configuration.IConfiguration Microsoft.Extensions.Logging.LoggerFactory.get_Configuration（）。

如 loggerFactory.AddSerilog（）; ，我尝试在 ConfigureServices services.AddSeriLog（） c>方法。
我也尝试安装软件包 Microsoft.Extensions.Logging ，也没有解决。 / p>
我还尝试从新模板中替换 Program.cs 文件的内容，如下所示。
public class Program
{
public static void Main（string [ ] args）
{
BuildWebHost（args）.Run（）;
}
public static IWebHost BuildWebHost（string [] args）=>
WebHost.CreateDefaultBuilder（args）
.UseStartup< Startup>（）
.Build（）;
}
有人可以帮我解决此问题吗？
更新
添加软件包 Microsoft.AspNetCore.All 解决了此问题。但是我真的不想添加此软件包，因为这会将许多不需要的引用添加到该单个软件包中。
必需的软件包是
Microsoft.Extensions.Logging.Configuration
我添加了解决该问题的软件包。
< PackageReference Include = Microsoft.Extensions.Logging.Configuration Version = 2.0.0-preview2-final />
I just updated my visual studio to preview 4 and updated all my packages from Core 2.0 Preview 1 Final to Core 2.0 Preview 2 Final. Below is my csproj file after all upgradation.
<ItemGroup>
<PackageReference Include="HtmlAgilityPack" Version="1.5.2-beta2" />
<PackageReference Include="Humanizer.Core" Version="2.2.0" />
<PackageReference Include="Microsoft.AspNetCore" Version="2.0.0-preview2-final" />
<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.0.0-preview2-final" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="2.0.0-preview2-final" />
<PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="2.0.0-preview2-final" />

Below is the raw exception details.
System.MissingMethodException: Method not found: 'Microsoft.Extensions.Configuration.IConfiguration Microsoft.Extensions.Logging.LoggerFactory.get_Configuration()'.

public class AppProgram

})
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.Build();
host.Run();
}
}
}
Startup.cs (I had to comment out loggerFactory.AddSeriLog() call because it was generating error just after I updated all the packages.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
services.AddSwaggerGen(c =>
{
// removed for brevity
});
// DI statements have been removed for brevity.
Log.Logger = new LoggerConfiguration()
.ReadFrom.Configuration(Configuration)
.CreateLogger();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
//loggerFactory.AddSerilog();
app.UseMvc();
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
});
}
As suggested in the error message from loggerFactory.AddSerilog();, I tried adding services.AddSeriLog() in my ConfigureServices method.
I also tried installing package Microsoft.Extensions.Logging, also didn't fix.
I also tried replacing content of Program.cs file from the new template as below. This also didn't work.
public class Program
{
public static void Main(string[] args)
{
BuildWebHost(args).Run();
}
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.Build();
}
Can someone please help me fixing this issue?
Update
Adding package Microsoft.AspNetCore.All solves the issue. But I really do not want to add this package as this adds many unwanted references packaged into this single package.
Required package is
Microsoft.Extensions.Logging.Configuration
I added the package which resolved the issue.
<PackageReference Include="Microsoft.Extensions.Logging.Configuration" Version="2.0.0-preview2-final" />
这篇关于从2.0.0-preview1-final升级到2.0.0-preview2-final之后的System.MissingMethodException的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
