在WPF自托管asp.net核心应用程序中加载视图 [英] Loading views in WPF self-host asp.net core application

问题描述

我们需要在WPF APP中自托管一个Asp.Net Core应用程序，API可以正常工作，但是在加载cshtml视图时会遇到一些问题.

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!");
        }
    }

URL http://127.0.0.1:9388/api/test 正在运行！ (网络API) 但是，当我们导航到 http://127.0.0.1:9388/myview 时，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上没有例外.

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

推荐答案

好的，现在可以使用了！ 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WPF projet迁移到VS2017格式，方法如下: 如何将Wpf项目迁移到新的VS2017格式(找到@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)您的cshtml必须具有构建选项内容"，但是csproj上的指令需要删除，否则它将无法编译.

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