ASP.NET Core 3.1 static files cannot be accessed

Question

I have some JSON data-configuration files that I wish to have them online as static files and read them upon my web-service initialization. So, I wish to access them internally from my code, not to make them public to external access.

Following the instructions (below) I placed them inside a /wwwroot/Static folder and used app.UseStaticFiles(); in Startup.Configure(), then I try to read them via both HTML and C# code using the "~/Static/*.json" notation but it does not work from C# code.

instructions reference: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/static-files?view=aspnetcore-3.1

When locally, I am getting error: DirectoryNotFoundException: Could not find a part of the path '...\Repos\VS2019\my-project-folder\~\Static\filename.json'.

So, the ~ symbol is not translated to wwwroot folder name.

When online (as Azure App Service) I am getting: HTTP ERROR 500

What I have done wrong?

Use HostingEnvironment to get physical location:

public HomeController(IHostingEnvironment hostingEnvironment)
    {
        string data= System.IO.File.ReadAllText(hostingEnvironment.WebRootPath.ToString()+ @"\Static\test.json");
    }

if Application is web Api then use ContentRoot instead of WebRootPath.
