我有一个.NET Core控制台应用程序并已运行dotnet publish.但是,我无法弄清楚如何从命令行运行应用程序.任何提示？

我们目前正在使用ASP.NET Core重写/转换我们的ASP.NET WebForms应用程序.尽量避免重新设计.

我们HttpContext在类库中使用了一个部分来检查当前状态.如何HttpContext.Current在.NET Core 1.0中访问？

 var current = HttpContext.Current;
     if (current == null)
      {
       // do something here
       // string connection = Configuration.GetConnectionString("MyDb");
      }

我需要访问它才能构建当前的应用程序主机.

$"{current.Request.Url.Scheme}://{current.Request.Url.Host}{(current.Request.Url.Port == 80 ? "" : ":" + current.Request.Url.Port)}";

我正在尝试使用nopCommerce(这是用.NET Core编写的),但当我想运行该项目时,我面临52个错误告诉我运行一个nuget包恢复

资产文件〜\ obj\project.assets.json'找不到.运行NuGet包还原以生成此文件.Nop.Web.MVC.Testsote

当我使用右键单击解决方案并选择Restore Nuget Packages时,我收到以下消息:

所有软件包都已安装,无需恢复.

但那些52个错误仍然存​​在,并且在工具 - > NuGet包管理器 - >管理NuGet包解决方案中解决方案 没有安装任何东西,我最近也将我的VS2017更新为15.5.4

我正在尝试访问我的 Asp.net core v6 应用程序 Program.cs 文件中的 appsettings.json，但在此版本的 .Net 中，Startup 类和 Program 类合并在一起，并且 using 和 another 语句被简化并从 Program 中删除。CS。在这种情况下，如何访问 IConfiguration 或如何使用依赖注入？

代码

这是 Asp.net 6 为我创建的默认 Program.cs

var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddControllers();
builder.Services.AddStackExchangeRedisCache(options =>
{
    options.Configuration = "localhost:6379";
});

builder.Services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new() { Title = "BasketAPI", Version = "v1" });
});
var app = builder.Build();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "BasketAPI v1"));
}
app.UseHttpsRedirection(); …

我有一个相当奇怪的问题正在发生.

这是我的代码

private async Task BreakExpectedLogic()
{
    bool test = false;
    if (test == true)
    {
        Console.WriteLine("Hello!");
        throw new Exception("BAD HASH!");
    }
}

看起来真的很简单,不应该打Console.WriteLine或者throw.由于某种原因,它总是击中throw.

如果我移动throw到自己的方法然后它工作正常.我的问题是它是如何忽略if阻挡并击中阻挡的throw new Exception

编辑1我已更新我的代码以包含签名,我删除了与此问题无关的所有内容并运行它,它仍然发生

当我PM> Remove-Migration -context BloggingContext使用EF Core在VS2015中运行ASP.NET Core项目时,我收到以下错误:

System.InvalidOperationException: The migration '20160703192724_MyFirstMigration' has already been applied to the database. Unapply it and try again.

我在本地克隆了ASP.NET Core SignalR Repo,并尝试在以下环境中打开解决方案.

IDE

Microsoft Visual Studio Enterprise 2015

我最终看到了很多这类错误消息:

我想知道如何以正确的方式解决这个问题.

.NET Core和ASP.NET Core之间究竟有什么区别？

它们是互相排斥的吗？我听说asp.net核心是基于.net核心构建的,但也可以构建在完整的.net框架上.

那么ASP.NET Core到底是什么？

我在:OSX 10.11.6,Homebrew版本0.9.9m OpenSSL 0.9.8zg 2015年7月14日

我正在尝试使用dotnetcore并遵循他们的指示,

我升级/安装了最新版本的openssl:

> brew install openssl
==> Downloading https://homebrew.bintray.com/bottles/openssl-1.0.2h_1.el_capitan.bottle.tar.gz
Already downloaded: /Users/administrator/Library/Caches/Homebrew/openssl-1.0.2h_1.el_capitan.bottle.tar.gz
==> Pouring openssl-1.0.2h_1.el_capitan.bottle.tar.gz
==> Caveats
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local.

Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries

Generally there are no consequences …

ASP.NET Core支持一个新的配置系统,如下所示:https: //docs.asp.net/en/latest/fundamentals/configuration.html

.NET Core控制台应用程序是否也支持此模型？

如果不是以前app.config和ConfigurationManager型号的替代品？
