Question

如果我的Web项目升级到asp.net core 3.0，我已经升级了一些，并试图将它们推送到IIS Web服务器。我安装了.net core 3.0托管包和运行时，并卸载了旧版本，以防万一。

我尝试加载页面，但出现错误：

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
Error Code     0x8007000d
Config Error       
Config File    \\?\C:\inetpub\MySite\web.config

下面是我的web.config：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\MySite.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="">
        <environmentVariables>
          <environmentVariable name="EXCLUDED_LINE" value="Test" />
          <environmentVariable name="COMPLUS_ForceENC" value="1" />
        </environmentVariables>
      </aspNetCore>
    </system.webServer>
  </location>
</configuration>

除了.net版本以外，我没有在服务器上进行任何其他更改-我将直接替换以前的工作项目。

startup.cs：

using Microsoft.Extensions.Hosting;

namespace MySite
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

            services.AddAuthentication(IISDefaults.AuthenticationScheme);

            services.AddTransient<IClaimsTransformation, CustomClaimsTransformer>();

            services.AddSingleton<IAuthorizationHandler, CheckADGroupHandler>();

            services.AddRazorPages().AddFluentValidation();

            services.AddDbContext<MyContext>(options =>
                options.UseSqlServer(
                    "Data Source=MYSERVER\\SQLEXPRESS;Initial Catalog=MyDB;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False"));
        }

            // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
                app.UseHsts();
            }

            app.UseRouting();
            app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints => endpoints.MapRazorPages());

            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

        }
    }
}

  </ItemGroup>

  </ItemGroup>

</Project>

尽管我可以浏览web.config，但我很讨厌手动将其复制到测试IIS，大多数页面仅显示错误500。

我在新服务器和在安装3.0之前卸载了core 2.2的服务器上都遇到了该问题。最终，我发现一台可以正常工作的服务器，并意识到我忘记了卸载旧的托管捆绑软件，因此它同时具有2.2和3.0

最后，我通过在服务器上与asp.net core 3.0托管一起安装了asp.net core 2.2托管捆绑包来修复了它。网站现在可以正常工作。

从Core 2.2升级到ASP.NET Core 3.0后，IIS配置错误
