当我开发一个我没有VS2015的应用程序时,我无法做到

> Hookup launchSettings.json到我的应用程序
>更改启动设置,例如托管环境,launchUrl或默认端口5000等.

如果我在没有Visual Studio的情况下开发,如何设置这些属性？

据我所知,launchSettings.json是特定于Visual Studio的.从documentation：

This file holds settings specific to each profile Visual Studio is configured to use to launch the application,including any environment variables that should be used.

您需要一种不同的方式来设置所需的选项：

绑定地址和端口

在Program.cs中引导应用程序时可以配置此项：

public static void Main(string[] args)
{
    var host = new WebHostBuilder()
        .UseKestrel()
        .UseUrls("http://localhost:8080") // name and port to listen on
        .UseContentRoot(Directory.GetCurrentDirectory())
        .UseStartup<Startup>()
        .Build();

    host.Run();
}

托管环境

从同一个docs：

ASP.NET Core references a particular environment variable,ASPNETCORE_ENVIRONMENT to describe the environment the application is currently running in. This variable can be set to any value you like,but three values are used by convention: Development,Staging,and Production.

只需为您的平台设置适当的环境变量为“开发”,“暂存”,“生产”等.ASP.NET Core将读取值,所有IHostingEnvironment逻辑都将起作用.

在Windows中,您可以在GUI或命令行中设置环境变量：

setx ASPNETCORE_ENVIRONMENT "Development"

启动网址

在运行应用程序时,Visual Studio会自动打开浏览器,从而尝试提供帮助.如果您使用的是dotnet,则必须手动执行此操作.

我没有尝试过,但Visual Studio Code的这个插件可能会给你这个功能：Visual Studio Chrome Debugger

到目前为止,我有以下代码,但我不知道如何将类,引用等添加到项目中.

public void Build()
{
    string projectFile = string.Format(@"{0}\{1}.csproj",Common.GetApplicationDataFolder(),_project.Target.AssemblyName);
    Microsoft.Build.Evaluation.Project p = new Microsoft.Build.Evaluation.Project();

    ProjectCollection pc = new ProjectCollection();

    Dictionary<string,string> globalProperty = new Dictionary<string,string>();

    globalProperty.Add("Configuration","Debug");
    globalProperty.Add("Platform","x64");

    buildrequestData buildrequest = new buildrequestData(projectFile,globalProperty,null,new string[] { "Build" },null);

    p.Save(projectFile);

    buildresult buildresult = BuildManager.DefaultBuildManager.Build(new BuildParameters(pc),buildrequest);
}

谢谢.

class Program
{
    static void Main(string[] args)
    {
        var root = ProjectRootElement.Create();
        var group = root.AddPropertyGroup();
        group.AddProperty("Configuration","Debug");
        group.AddProperty("Platform","x64");

        // references
        AddItems(root,"Reference","System","System.Core");

        // items to compile
        AddItems(root,"Compile","test.cs");

        var target = root.AddTarget("Build");
        var task = target.AddTask("Csc");
        task.SetParameter("Sources","@(Compile)");
        task.SetParameter("OutputAssembly","test.dll");

        root.Save("test.csproj");
        Console.WriteLine(File.ReadAllText("test.csproj"));
    }

    private static void AddItems(ProjectRootElement elem,string groupName,params string[] items)
    {
        var group = elem.AddItemGroup();
        foreach(var item in items)
        {
            group.AddItem(groupName,item);
        }
    }
}

请注意,这只是创建proj文件.它没有运行它.此外,“配置”和“平台”等属性仅在Visual Studio生成的proj文件的上下文中有意义.除非您按照Visual Studio自动执行的方式添加更多具有条件的属性组,否则它们不会真正执行任何操作.

就像我在评论中指出的那样,我认为这是错误的做法.您真的只想要动态编译源代码,这可以通过CodeDom获得：

using System.CodeDom.Compiler;

class Program
{
    static void Main(string[] args)
    {
        var provider = CodeDomProvider.CreateProvider("C#");
        string[] sources = {
                               @"public abstract class BaseClass { public abstract void test(); }",@"public class CustomGenerated : BaseClass { public override void test() { System.Console.WriteLine(""Hello World""); } }"
                           };

        var results = provider.CompileAssemblyFromSource(new CompilerParameters() {
            GenerateExecutable = false,ReferencedAssemblies = { "System.dll","System.Core.dll" },IncludeDebuginformation = true,CompilerOptions = "/platform:anycpu"
        },sources);
        if (results.Errors.Count > 0)
        {
            Console.WriteLine("{0} errors",results.Errors.Count);
            foreach(CompilerError error in results.Errors)
            {
                Console.WriteLine("{0}: {1}",error.ErrorNumber,error.ErrorText);
            }
        }
        else
        {
            var type = results.CompiledAssembly.GetType("CustomGenerated");
            object instance = Activator.CreateInstance(type);
            type.getmethod("Test").Invoke(instance,null);
        }
    }
}

现在我们尝试使用类似的设置构建安装项目.看起来MSBuild不喜欢.vDProj.任何想法我们怎么能这样做？

谢谢,
