Visual Studio 2015 .NET Core 1.0 自动构建

Question

I am working on a .NET Core 1.0 web application in Visual Studio 2015 Community.

Apparently there is an autobuild function, where I should be able to run without debugging ( ctrl + F5 ) and any changes I make to my code should be reflected simply by refreshing the page, but I cannot get this working.

Any changes I make to my views is reflected with a page refresh regardless of whether or not I am running with or without debugging ( F5 or ctrl + F5 ), but any changes I make to controllers or other code is not.

When I run with or without debugging, I get a command prompt that shows up.

If I run the project without debugging and then try and build, I get the following error

Projects\\MyProject\\bin\\Debug\\netcoreapp1.0\\ASPNET_Core_1_0.dll' for writing -- 'The process cannot access the file 'C:\\Users\\Adam\\Desktop\\Visual Studio Projects\\MyProject\\bin\\Debug\\netcoreapp1.0\\ASPNET_Core_1_0.dll' because it is being used by another process.'

So if I run a project without debugging, I need to close this command prompt, and then re-run with or without debugging to see the changes.

Any help would be greatly appreciated.

I've noticed that if I run my application with IIS Express without debugging, I can get this autobuild function. After I make some changes in my code, I can get that result by pressing F5 in the browser.

However, if I run it directly using WebApplication as target, I cannot get this autobuild function. I have to modify project.json as in the example below:

"tools": {
  "Microsoft.DotNet.Watcher.Tools": "1.0.0-preview2-final"
},

And I have to add some lines in the profiles section to launchSettings.json in the Properties folder:

"dotnet watch": {
      "executablePath": "C:\\Program Files\\dotnet\\dotnet.exe",
      "commandLineArgs": "watch run --server.urls http://*:5000",
      "launchBrowser": true,
      "launchUrl": "http://localhost:5000/",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }

After that, I can get this autobuild fuction by selecting dotnet watch as the target, with or without debugging. Thanks to asp.net core and Rehan Saeed .
