In Visual Studio, create new ASP.NET Core Web Application (.NET Core). Use template \"Web Application\"\r\n2. Run the application without debugging\r\n3. Browse to About page (e.g. http://localhost:50074/Home/About)\r\n\r\nTest case A:\r\n4. Edit HomeController.cs About() contoller to \r\n`ViewData[\"Message\"] = \"Hello world 2!\";`\r\nand save the change\r\n5. Hit F5 in browser and see how long it takes for IIS Express to respond with the change\r\n\r\nTest case B:\r\n4. Edit Startup.cs Configure() by adding a line:\r\n`int foo=1;`\r\n5. Hit F5 in browser\r\n\r\nTest case C:\r\n4. Edit Startup.cs Configure() by adding a line:\r\n`app.Run(async (context) => { await context.Response.WriteAsync(\"Hello World3!\"); });`\r\n(requires also: `using Microsoft.AspNetCore.Http;`)\r\n5. Hit F5 in browser\r\n\r\n\r\n\r\n## Expected  behavior\r\n\r\nAll use cases should respond within 5 seconds.\r\n\r\n## Actual behavior\r\n\r\nAll cases compile within 2.5 seconds\r\n1>  Time elapsed 00:00:02.3853349\r\n\r\nBut the total response time until IIS Express to view the change:\r\nCase A: around 9-12 seconds\r\nCase B: around 9-12 seconds\r\nCase C:  around 4-5 seconds\r\n\r\nSo where is the extra 5 seconds wasted here?\r\n\r\nNote: Test case A results in Core 1.0 RC1: IIS Express responded within 4-5 seconds as expected.\r\n\r\nAlso compile time seems oddly long for simple Hello world application (I have fast SSD, 10GB of free RAM, and other CPU usage below 10%)\r\n\r\n## Environment data\r\n.NET Command Line Tools (1.0.0-preview2-003121)\r\n\r\nProduct Information:\r\n Version:            1.0.0-preview2-003121\r\n Commit SHA-1 hash:  1e9d529bc5\r\n\r\nRuntime Environment:\r\n OS Name:     Windows\r\n OS Version:  10.0.10586\r\n OS Platform: Windows\r\n RID:         win10-x64"},"comment":{"url":"https://api.github.com/repos/aspnet/Tooling/issues/comments/237014864","html_url":"https://github.com/aspnet/Tooling/issues/690#issuecomment-237014864","issue_url":"https://api.github.com/repos/aspnet/Tooling/issues/690","id":237014864,"user":{"login":"mlorbetske","id":1414993,"avatar_url":"https://avatars.githubusercontent.com/u/1414993?v=3","gravatar_id":"","url":"https://api.github.com/users/mlorbetske","html_url":"https://github.com/mlorbetske","followers_url":"https://api.github.com/users/mlorbetske/followers","following_url":"https://api.github.com/users/mlorbetske/following{/other_user}","gists_url":"https://api.github.com/users/mlorbetske/gists{/gist_id}","starred_url":"https://api.github.com/users/mlorbetske/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mlorbetske/subscriptions","organizations_url":"https://api.github.com/users/mlorbetske/orgs","repos_url":"https://api.github.com/users/mlorbetske/repos","events_url":"https://api.github.com/users/mlorbetske/events{/privacy}","received_events_url":"https://api.github.com/users/mlorbetske/received_events","type":"User","site_admin":false},"created_at":"2016-08-02T19:23:33Z","updated_at":"2016-08-02T19:23:33Z","body":"TFS Bug#247569"}}
