自托管 ASp.net 核心 2.2 应用程序，未找到视图 'Index'。搜索了以下位置

Question

我正在创建 ASP.NET 核心 Web 应用程序并通过控制台托管它。

我正在使用 IdentitySvr4 Quick Start UI 并将所有文件添加到我的项目中。

现在，当我通过运行控制台启动服务器并浏览到 http://localhost:44322/ 时，出现错误，

InvalidOperationException: The view 'Index' was not found. The following locations were searched:
/Views/Home/Index.cshtml
/Views/Shared/Index.cshtml
/Pages/Shared/Index.cshtml

我已将此项目创建为控制台应用程序，并在此过程中添加了所有 nugets。

网络服务器启动并在端口上侦听，但不知何故视图引擎无法理解。

主程序：

class Program
{
        static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args).UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseUrls("http://*:44322")
            .UseStartup<Startup>();
}

启动class：

public class Startup
{

        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
            var signingCertificate = new X509Certificate2(Helpers.GetCertificate());
            services.AddIdentityServer()
                .AddSigningCredential(new X509Certificate2(signingCertificate))
                .AddTestUsers(InMemoryConfiguration.Users().ToList())
                .AddInMemoryClients(InMemoryConfiguration.Clients().ToList())
                  .AddInMemoryApiResources(InMemoryConfiguration.ApiResources());

            services.AddMvc();


        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            loggerFactory.AddConsole();

            app.UseDeveloperExceptionPage();

            app.UseIdentityServer();

            app.UseStaticFiles();

            app.UseMvcWithDefaultRoute();

        }
}

Answer 1

通常我不会回答我的问题，只是添加评论，但我认为这将为开发人员节省很多精力和痛苦。

很简单，

我用 Notepad++ 编辑了 .csproj 并找到了以下设置：

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.2</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="IdentityServer4" Version="2.3.2" />
    <PackageReference Include="Microsoft.AspNetCore" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Diagnostics" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Hosting" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Http" Version="2.2.2" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Server.Kestrel" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.2.0" />
  </ItemGroup>

</Project>

引用 webproj 后，只需将根目录从 "Microsoft.NET.Sdk" 更改为 "Microsoft.NET.Sdk.Web"

即可将其更改为 webproj

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.2</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="IdentityServer4" Version="2.3.2" />
    <PackageReference Include="Microsoft.AspNetCore" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Diagnostics" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Hosting" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Http" Version="2.2.2" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Server.Kestrel" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.2.0" />
  </ItemGroup>

</Project>

就是这样。不确定为什么所有的应用程序逻辑都将取决于项目类型（因为它可以托管在任何地方），但工作起来很有魅力。

Answer 2

对我来说，错误出现在我的 .csproj 文件中。 ItemGroup 内容不包括 Index.cshtml。我删除了这个引用，现在我可以导航到 Index.cshtml.

<pre><code>
<ItemGroup>
<Content Remove="Views\Employee\Delete.cshtml" />
<Content Remove="Views\Employee\Index.cshtml" />
</ItemGroup>
</code></pre>

Answer 3

我编辑了 .csproj

只需删除它（如果存在）

"<RazorCompileOnBuild>false</RazorCompileOnBuild>"
"<RazorCompileOnPublish>false</RazorCompileOnPublish>"

来自 <PropertyGroup>

默认情况下 <PropertyGroup>

中找不到“RazorCompileOnBuild”和“RazorCompileOnPublish”

dotnet clean
