我已经开始使用ASP.Net核心Web API作为后端的前端Angular应用程序的项目。但是，不是使用SPA的默认模板（用于Angular），而是我自己决定这样做。因此，我创建了一个空白的ASP.NET Core项目，然后使用Angular CLI添加了Angular项目。从字面上看，我在Angular项目配置中唯一更改的是angular.json中的outputPath-我将其更改为../wwwroot。
然后我在.Net应用程序的Startup类中设置所有内容。
我从ng serve开始创建角度，然后使用Visual Studio构建.net项目。但是，Angular应用程序在检测到其文件之一中的更改时不会刷新/更改内容。有趣的是，它进行了一些重建，但是除非我停止应用程序，运行ng build，然后再使用ng serve重新启动，否则新内容将不会出现。我相信我弄乱了两个项目中的配置，因此将不胜感激。我在下面提供了一些代码
这是我的Startup类（我发现所有与DI或授权设置有关的东西都隐藏了，因为我发现它无关紧要）
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.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
//Setting up DbContext, DI and authorization
services.AddSpaStaticFiles(spa =>
{
spa.RootPath = "wwwroot";
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseAuthentication();
app.UseStaticFiles();
app.UseSpaStaticFiles();
app.UseMvc();
app.UseSpa(spa =>
{
spa.Options.SourcePath = "client-app";
});
}
}
这是我的angular.json

由于您正在使用其他服务器而不是其中包含的webpack开发服务器，因此您需要构建输出并将其放置在自己的服务器wwwroot中。可能很乏味，但是最好的选择是在开发时在构建上使用--watch标志
尝试此操作以进行本地开发。
ng build --watch
