v8-9: Replace Server.MapPath

[LottePitcher]

v8

var appDataFolder = UmbracoContext.HttpContext.Server.MapPath("~/App_Data");

v9

The App_Data folder is no longer a special 'protected' folder. Steps can be taken to ensure that all its contents is protected, but for our purposes we actually don't need it to be protected. So we chose a different folder name to avoid future confusion about whether App_Data is actually protected or not.

public class GuestbookApiController : UmbracoApiController
{
    private readonly IWebHostEnvironment _webHostEnvironment;

    public GuestbookApiController(IWebHostEnvironment webHostEnvironment)
    {
        _webHostEnvironment = webHostEnvironment;
    }

    public string GetEntries(string id)
    {
       var githubFolder = _webHostEnvironment.ContentRootPath + "\\wwwroot\\github";
    }
}

PS we know it is good practice to create paths using Path.Combine instead of the approach above. Something else to do ;-)
