将带有类库的ASP.Net Core Web App发布到Azure时，在主页上出现500错误
我一直在尝试将我的Web应用程序部署到Azure，但在第一页上出现500错误。我假设这是因为我在第一页上引用的模型存在问题，该模型在我的解决方案中被引用到类库中。 这是项目的外观
我之前在引用类库方面遇到了一些问题，但到目前为止，我已经能够解决这些问题并成功构建这两个项目。该项目在IISExpress中运行良好。但是当我尝试将其部署到Azure时，我的主页上出现了500错误。这是代码：
@using LNCLibrary.Models.HomeViewModel
@model HomeViewModel
@{
ViewData["Title"] = "Home Page";
}
@inject SignInManager<ApplicationUser> SignInManager
@inject UserManager<ApplicationUser> UserManager

我确信它一定是我用于页面的模型的一个问题，因为它驻留在Web应用程序项目中但引用了类库中的模型，所以我认为这是另一个问题图书馆或参考。但问题是我无法弄清楚如何在Azure中调试以查看由于500错误导致的实际问题。这是ViewModel，Model和Controller：
视图模型：
using System;
using System.Collections.Generic;
using System.Text;
namespace LNCLibrary.Models.HomeViewModel
{
public class HomeViewModel
{
public ICollection<Product> ShopProducts { get; set; }
}
}
型号：
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Text;
namespace LNCLibrary.Models
{
public enum Category
{
Shirts,
Accesories,
}
public enum Gender
{
Men,
Women,
Both
}
public class Product
{
public int ID { get; set; }
[Display(Name ="Name")]
public string ProductName { get; set; }
public int Price { get; set; }
[Display(Name = "Gender")]
public Gender GenderOption { get; set; }
public int Quantity { get; set; }
public Category Category { get; set; }
[Display(Name ="Created")]
public DateTime DateCreated { get; set; }
[Display(Name = "Description")]
public string ProductDescription { get; set; }
public ICollection<Size> AvailableSizes { get; set; }
[Display(Name = "Profile Picture")]
public string ProfilePicture { get; set; }
}
}
控制器：
private readonly ApplicationDbContext _context;
public HomeController(ApplicationDbContext context)
{
_context = context;
}
public async Task<IActionResult> Index()
{
HomeViewModel HVM = new HomeViewModel();
HVM.ShopProducts = await _context.Products.ToListAsync();
return View(HVM);
}
有什么想法吗？我很难过。

使用VS中的“发布”对话框将Azure App Service废除后，打开Server Explorer（“视图”>“ Server Explorer”），右键单击App Service实例，然后选择“附加调试器”。 在正在运行的ASP.NET应用程序中，重现该错误或在此之前设置断点。 断点应在Visual Studio中命中。 喜欢本地！

在starup.cs中有一种方法Configure。启用app.UseDeveloperExceptionPage()和app.UseDatabaseErrorPage()可以详细查看错误。
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
}
else
{
//app.UseExceptionHandler("/Home/Error");
app.UseDeveloperExceptionPage(); // add this to see error
app.UseDatabaseErrorPage(); // add this to see error
}
}
