刚刚启动了一个新的.NET Core 2.0应用程序，但出现奇怪的突然行为，似乎无法找到任何东西。打的.Run()时.NET Core 2.0 BasePath错误
以下错误弹出我的BuildWebHost().：

这里是我的Program.cs

public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)

灿” t似乎把我的头围绕着这个！
更新1：
运行在命令行中我的项目时，它运行IIS槽快速，没有错误时使用错误，只弹出。
这里是我的launchSettings
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:51592/swagger",
"sslPort": 0
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"API": {
"commandName": "Project",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"applicationUrl": "http://localhost:5000/swagger"
}
}
}
虽然没有关系。您应该在BL中拥有一个等效的配置服务，并将引用转换为DAL。使用当前的设置，您可以直接从上层访问DAL，这可以打开BL层的潜力。理想情况下，顶层不应该知道有关DAL的任何信息。 – bilpor
这实际上是我现在困扰了我的一段时间，但没有花时间去考虑它。你有一个具体的例子，我应该如何将我的BL <-> DAL的东西变成m BL？ – TanguyB
我这样做，我会尽力挖掘出来.....我没有在我目前所在的网站上。但我会告诉你我是如何做到这一点的更新。 – bilpor
