Azure错误信息如下：
.Net Core：应用程序启动异常： System.IO.FileNotFoundException: 找不到配置文件'appsettings.json'，且该文件不是可选的。
所以这有点模糊。我似乎无法确定问题所在。我正在尝试将.Net Core Web API项目部署到Azure上，并且遇到了这个错误：
:( 哎呀，500内部服务器错误 启动应用程序时发生错误。
我已经部署了普通的.Net WebAPI，它们可以正常工作。我已经按照在线教程进行操作，也可以正常工作。但是我的项目出了问题。在Web.config上启用stdoutLogEnabled并查看Azure Streaming日志，会得到以下结果：
最终，它起作用了。 我一定是按照旧的RC1示例操作，没有意识到这一点。

好的，这似乎很简单。它找不到appsettings.json文件。查看我的配置（startup.cs），它看起来非常清晰定义。我的启动代码如下：
public class Startup
{
private static string _applicationPath = string.Empty;
private static string _contentRootPath = string.Empty;
public IConfigurationRoot Configuration { get; set; }
public Startup(IHostingEnvironment env)
{
_applicationPath = env.WebRootPath;
_contentRootPath = env.ContentRootPath;
// Setup configuration sources.
var builder = new ConfigurationBuilder()
.SetBasePath(_contentRootPath)
.AddJsonFile("appsettings.json")
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);
if (env.IsDevelopment())
{
// This reads the configuration keys from the secret store.
// For more details on using the user secret store see http://go.microsoft.com/fwlink/?LinkID=532709
builder.AddUserSecrets();
}
builder.AddEnvironmentVariables();
Configuration = builder.Build();
}
private string GetXmlCommentsPath()
{
var app = PlatformServices.Default.Application;
return System.IO.Path.Combine(app.ApplicationBasePath, "Quanta.API.xml");
}
// 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 http://go.microsoft.com/fwlink/?LinkID=398940
public void ConfigureServices(IServiceCollection services)
{
var pathToDoc = GetXmlCommentsPath();
services.AddDbContext<QuantaContext>(options =>
options.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"],
b => b.MigrationsAssembly("Quanta.API")));
//Swagger
services.AddSwaggerGen();
services.ConfigureSwaggerGen(options =>

app.UseCors(builder =>

app.UseExceptionHandler(

{
builder.Run(
async context =>
{
context.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
context.Response.Headers.Add("Access-Control-Allow-Origin", "*");
var error = context.Features.Get<IExceptionHandlerFeature>();
if (error != null)
{
context.Response.AddApplicationError(error.Error.Message);
await context.Response.WriteAsync(error.Error.Message).ConfigureAwait(false);
}
});
});
app.UseMvc(routes =>

// Uncomment the following line to add a route for porting Web API 2 controllers.

using (var serviceScope = app.ApplicationServices

这段代码在本地运行良好，但一旦发布到Azure上就会失败。我很迷惑。我创建了一个新的 .Net Core 项目，并成功部署到Azure。但是这个项目花费了我所有的时间，似乎无法运行。我准备将无法运行的项目中的代码复制并粘贴到一个新项目中，但我真的很好奇是什么导致了错误。
有任何想法吗？
编辑： 我的Program.cs如下：
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Hosting;
namespace Quanta.API
{
public class Program
{
public static void Main(string[] args)
{
var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.Build();
host.Run();
}
}
}
编辑2： 根据Frans的建议，我检查了publishOptions。它是：
"publishOptions": {
"include": [
"wwwroot",
"web.config"
]
我从一个正常工作的项目中获取了publishOptions，并进行了如下更改：
"publishOptions": {
"include": [
"wwwroot",
"Views",
"Areas/**/Views",
"appsettings.json",
"web.config"
]
},
虽然出现了500错误，但没有出现堆栈跟踪，指出无法加载appsettings.json文件。现在它抱怨连接到SQL的问题。我注意到我的SQL连接字符串代码在许多RC1博客文章中都提到了。.Net Core的RC2对此进行了更改。因此，我将其更新为：
"Data": {
"ConnectionStrings": {
"DefaultConnection": "Server=(localdb)\\MSSQLLocalDB;Database=QuantaDb;Trusted_Connection=True;MultipleActiveResultSets=true"
}
},
我将启动项更改为：
services.AddDbContext<QuantaContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"),
b => b.MigrationsAssembly("Quanta.API")));
最终，它起作用了。 我一定是按照旧的RC1示例操作，没有意识到这一点。
Content root path: D:\home\site\wwwroot。这是预期的吗？appsettings.json文件在文件夹中吗？ - adem caglin
