在没有.NET Core SDK的情况下将ASP.NET Core MVC作为控制台应用程序项目运行 [英] Running ASP.NET Core MVC as a Console Application Project without .NET Core SDK
问题描述
问题背景
我正在创建一个工具，可以生成MVC解决方案(* .sln)并使用msbuild构建它们，以便可以对其进行部署.该工具需要.NET Framework 4.5.2.
I'm creating a tool, tha generates MVC solutions(*.sln) and building(with msbuild) them so they could be deployed. Tool requires .NET Framework 4.5.2.
现在，我想生成ASP.NET Core MVC应用程序.这样的应用程序可以在4.5.X下运行，但是我不确定msbuild是否可以处理project.json(因此我正在使用packages.config)，并且我无法安装.NET Core，因为每个教程都指出这是开发ASP.NET的先决条件.核.目前，我正计划在Windows上部署生成的应用程序.
Now I want to generate ASP.NET Core MVC application. Such applications could be run under 4.5.X, but I'm unsure if msbuild could handle project.json(so i'm using packages.config) and I cannot install .NET Core as every tutorial indicate as prerequisite for developing ASP.NET Core. Currently I'm planning to deploy generated applications on Windows.
问题:
因此，我创建了一个简单的控制台应用程序，而不是.NET Core项目: 在那里，我已经安装了所有需要的软件包，例如:
So instead of .NET Core project I've created a simple console application: There I've installed there all packages needed, like:
<package id="Microsoft.AspNetCore.Mvc" version="1.0.1" targetFramework="net452" />
然后使用Kestrel自托管应用程序:
And SelfHosted the application using Kestrel:
public class Program {
static void Main() {
var host = new WebHostBuilder()
.UseKestrel()
.UseIISIntegration()
.UseStartup<Startup>()
.Build();
host.Run();
}
}
我添加了带有View的Controller.当我发出请求时，控制器被命中，但是View无法在运行时进行编译:
I've added Controller with a View. When I do a request, controller is hit, but View cannot be compiled in runtime:
此行为是否与我正在使用控制台应用程序而不是 ASP.NET Core Web应用程序有关?是否可以将功能齐全的MVC应用程序创建为简单的控制台应用程序?
Is this behavior related to the fact I'm using Console Application and not ASP.NET Core Web Application? Is it possible to create a full-featured MVC application as a simple console application?
更新:
我认为我已经找到了一种解决方法，灵感来自阅读github 问题:
I think I've found a workaround inspired from reading github issues:
public void ConfigureServices(IServiceCollection services) {
services.AddMvc()
.AddRazorOptions(options => {
var previous = options.CompilationCallback;
options.CompilationCallback = context => {
previous?.Invoke(context);
var refs = AppDomain.CurrentDomain.GetAssemblies()
.Where(x => !x.IsDynamic)
.Select(x => MetadataReference.CreateFromFile(x.Location))
.ToList();
context.Compilation = context.Compilation.AddReferences(refs);
};
});
}
这似乎使Razor呈现了我的观点.但是我不确定是否可以接受它作为解决方案.
That seems to make Razor to render my view. But I'm not sure yet if it can be accepted as a solution.
推荐答案
目前，无法使用MSBuild来构建.NET Core应用.但是可以创建一个控制台应用程序(不是.Net Core)并使用Nuget添加相同的程序包(逐步介绍).
Right now it's not possible to build a .NET Core app using MSBuild. But it's possible to create a Console application (not .Net Core) and add the same packages using Nuget (step-by-step bellow).
根据此路线图 ，这将在不久的将来成为可能.
According to this road map, it will be possible in the near future.

2016年第四季度/2017年第一季度
Q4 2016 / Q1 2017
这将是第一个次要更新，主要着眼于将.xproj/project.json替换为.csproj/MSBuild.项目格式更新应该是自动的.只需打开1.0项目，它就会更新为新的项目格式.在运行时和库中还将有新功能和改进.*
This will be the first minor update, mainly focused on replacing .xproj/project.json with .csproj/MSBuild. Project format update should be automatic. Just opening a 1.0 project will update it to the new project format. There will also be new functionality and improvements in the runtime and libraries.*
编辑(使用kestrel创建控制台应用程序的步骤):
EDIT (steps to create a console app with kestrel):
我创建了一个控制台应用程序(不是.NET Core控制台)，并且能够使用简单的MVC API运行kestrel.
I created a Console Application (not .NET Core console) and I was able to run kestrel with a simple MVC API.
这就是我所做的:
-
我看到了在现有.net核心应用程序中使用的依赖项，然后，我将它们添加为nuget引用:
I saw the dependencies I use in a existing .net core app, then, I added they as a nuget reference:
"Microsoft.AspNetCore.Mvc": "1.0.0",
"Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
"Microsoft.AspNetCore.Server.Kestrel": "1.0.0",
"Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0",
"Microsoft.Extensions.Configuration.FileExtensions": "1.0.0",
"Microsoft.Extensions.Configuration.Json": "1.0.0",
"Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0"
修改了主要方法:
Modified the main method:
static void Main(string[] args) {
var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.Build();
host.Run();
}
创建了一个Startup.cs(使用问题中提供的解决方法进行了更新):
Created a Startup.cs (UPDATED with the workaround provided in the question):
public class Startup {
public Startup(IHostingEnvironment env) {
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddEnvironmentVariables();
Configuration = builder.Build();
}
private IHostingEnvironment CurrentEnvironment { get; set; }
private IConfigurationRoot Configuration { get; }
public void ConfigureServices(IServiceCollection services) {
services.AddMvc().AddRazorOptions(options => {
var previous = options.CompilationCallback;
options.CompilationCallback = context => {
previous?.Invoke(context);
var refs = AppDomain.CurrentDomain.GetAssemblies()
.Where(x => !x.IsDynamic)
.Select(x => MetadataReference.CreateFromFile(x.Location))
.ToList();
context.Compilation = context.Compilation.AddReferences(refs);
};
});
}
public void Configure(IApplicationBuilder app) {
app.UseStaticFiles();
app.UseMvc(routes => {
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}
}
添加一个类作为我的MVC控制器:
Add a class to be my MVC Controller:
[Route("api/[controller]")]
public class ValuesController : Controller {
// GET api/values
[HttpGet]
public IEnumerable<string> Get() {
return new string[] { "value1", "value2" };
}
由于出现错误，我不得不将libuv.dll手动复制到bin文件夹中.
I had to copy mannualy the libuv.dll to the bin folder because I was getting an error.
通过这些步骤，我能够运行控制台应用程序. 在下面的图像中，您可以看到我的项目结构和运行的茶est:
With these steps I was able to run my console application. In the image bellow you can see my project structure and the kestrel running:
