在 WPF 自托管 asp.net 核心应用程序中加载视图

问题描述

我们需要在 WPF APP 中自托管 Asp.Net Core 应用程序，API 工作正常，但加载 cshtml 视图时出现一些问题.

We need to self-host an Asp.Net Core application in a WPF APP, APIs are working fine but there is some issues loading cshtml views.

这是我们的代码:主机生成器:

Here is our code: Host Builder:

public static class HostBuilder
    {
        private static IWebHost host;

        public static async Task Start()
        {
            if (host == null)
            {
                var ip = System.Net.IPAddress.Parse("127.0.0.1");
                var port = 9388;

                host = new WebHostBuilder()
                   .UseKestrel(options =>
                   {
                       options.Listen(ip, port);
                   })
                   .UseStartup<HostStartup>()
                   .Build();

                await host.RunAsync();
            }
        }

    }

主机启动:

public class HostStartup
    {
        public IConfiguration Configuration { get; }

        public HostStartup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();
        }

        public void Configure(IApplicationBuilder app, IHostingEnvironment env, System.IServiceProvider serviceProvider)
        {

            app.UseMvcWithDefaultRoute();
        }
    }

控制器:

[AllowAnonymous]
    [Route("api")]
    public class LoginController : Controller
    {
        [HttpGet]
        [Route("/myview")]
        public ViewResult MyView()
        {
            var v = View("myview");
            return v;
        }

        [HttpGet]
        [Route("test")]
        public IActionResult Test()
        {
            return Ok("Good!");
        }
    }

网址 http://127.0.0.1:9388/api/test 有效！(网络 API)但是当我们导航到 http://127.0.0.1:9388/myview 浏览器显示 http 错误 500.

The url http://127.0.0.1:9388/api/test is working! (web API) But when we navigate to http://127.0.0.1:9388/myview browser shows http error 500.

我错过了什么吗?WPF 没有例外.

Am I missing something? There is no exceptions on WPF.

推荐答案

好的，现在可以了！您需要手动执行一些操作:

Ok, it's working now! You need to do a few things manually:

1) 将您的 WPF 项目迁移到 VS2017 格式，方法如下:如何将 Wpf 项目迁移到新的 VS2017 格式(寻找@stil 答案)

1) Migrate your WPF projet to VS2017 format, here is how: How-to migrate Wpf projects to the new VS2017 format (find for @stil answer)

2) 安装 Asp.net Core 和 Asp.net Core MVC

2) Install Asp.net Core And Asp.net Core MVC

3) 再次编辑 csproj 并将根 Sdk 属性从 Microsoft.NET.Sdk 更改为 Microsoft.NET.Sdk.Razor

3) Edit the csproj again and change the root Sdk attribute from Microsoft.NET.Sdk to Microsoft.NET.Sdk.Razor

4) 将您的 WPF 项目指向框架 4.6.2、4.7 > 不起作用！

4) Point your WPF project to framework 4.6.2, 4.7 > doesn't work!

5) 你的cshtml必须有构建选项Content"，但是，csproj上的指令需要去掉，否则编译不出来.

5) Your cshtml must have the build option "Content", but, the instruction on csproj need to be removed, otherwise, it'll not compile.
