关于SO有很多类似的问题,但我无法找到问题的解决方案。很明显我对.NET Core还不够熟悉......)
我有一个严格的ASP.NET核心应用程序,我正在尝试使用 dnx web 命令启动 Kestrel Web服务器,但它失败了,因为它似乎活动框架目标是 dnx451 (而不是 dnxcore50 )。
我的 global.json 如下所示:
{
"projects": [ "FolderName", "src", "test" ], // What IS the actual project name?
"sdk": {
"version": "1.0.0-rc1-update2",
"runtime": "coreclr",
"architecture": "x86"
}
}
摘自 project.json :
"commands": {
"web": "Microsoft.AspNet.Server.Kestrel --server.urls=http://*:8000/"
},
"frameworks": {
"dnxcore50": { }
}
最后,在 launchSettings.json :
中{
"profiles": {
"web": {
"commandName": "web",
"launchBrowser": false,
"launchUrl": "http://localhost:8000",
"environmentVariables": {
"Hosting:Environment": "Development"
},
"sdkVersion": "dnx-coreclr-win-x86.1.0.0-rc1-update2"
}
}
}
据我所知, project.json 中的依赖项与SDK版本匹配:
"dependencies": {
"EntityFramework.Commands": "7.0.0-rc1-final",
"EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final",
"Microsoft.ApplicationInsights.AspNet": "1.0.0-rc1",
"Microsoft.AspNet.Authentication.Cookies": "1.0.0-rc1-final",
"Microsoft.AspNet.Diagnostics.Entity": "7.0.0-rc1-final",
"Microsoft.AspNet.Identity.EntityFramework": "3.0.0-rc1-final",
"Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc1-final",
"Microsoft.AspNet.Mvc": "6.0.0-rc1-final",
"Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-rc1-final",
"Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final",
"Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final",
"Microsoft.AspNet.Tooling.Razor": "1.0.0-rc1-final",
"Microsoft.Extensions.CodeGenerators.Mvc": "1.0.0-rc1-final",
"Microsoft.Extensions.Configuration.FileProviderExtensions": "1.0.0-rc1-final",
"Microsoft.Extensions.Configuration.Json": "1.0.0-rc1-final",
"Microsoft.Extensions.Configuration.UserSecrets": "1.0.0-rc1-final",
"Microsoft.Extensions.Logging": "1.0.0-rc1-final",
"Microsoft.Extensions.Logging.Console": "1.0.0-rc1-final",
"Microsoft.Extensions.Logging.Debug": "1.0.0-rc1-final",
"Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.0.0-rc1-final"
}
然而,当我运行 dnx web 时,我得到以下内容:
System.InvalidOperationException: The current runtime target framework is not compatible with 'Okaymaker.Web'.
Current runtime target framework: 'DNX,Version=v4.5.1 (dnx451)'
Version: 1.0.0-rc1-16609
Type: Clr
Architecture: x86
OS Name: Windows
OS Version: 10.0
Runtime Id: win10-x86
Please make sure the runtime matches a framework specified in project.json
不确定为什么它说目前的目标框架 dnx451 ?我想我可以在运行 dnx web 之前运行 dnx use ,但我觉得配置应该为我处理设置?
如果我运行 dnvm list :
,这就是我看到的内容Active Version Runtime Architecture Location Alias

修改:通过安装 Visual Studio 2015 Update 3 和更新的工具,似乎可以解决/避免这些问题。 NET Core ,均可在以下网址获得:https://www.microsoft.com/net/core#windows

您必须使用dnvm use
将当前运行时设置为coreclr。 VisualStudio不够智能,但已发布的脚本足够智能,可以构建一个shell脚本来静态选择正确的引擎。
这是RC1的一个确认的设计缺陷(很抱歉懒得从ASP.NET社区Standup中搜索视频笔记)并在dotnet
命令行界面中得到修复。
