Accessing static files in SCD

Question

In the .NET CORE application, I'm using static files in wwwroot folder. while running it as dotnet run the index.html file is displayed smoothly and normal at localhost:port/ but after publishing the app as SCD self-contained development package, and run the .exe generated file, the static files are not displayed at the localhost:port/.

In the developer screen of the browser, I got 404 error that is file not found.

Answer 1

Add the corresponding statement in your project.json:

  "publishOptions": {
    "include": [
      "wwwroot",
      "appsettings.json",
      "web.config"
    ]
  },

Answer 2

Apparently the files other than .cs as not packaged, and needed to be added manually to the publish folder.

I've the below example for sending html file as attached email:

and the files structures are:

project.json

{
  "version": "1.0.0-*",
  "buildOptions": {
    "debugType": "portable",
    "emitEntryPoint": true
 },
"runtimes": {
    "win10-x64": {},
    "win10-x86": {}
},
"dependencies": {
   "NETStandard.Library": "1.6.0",
   "Microsoft.NETCore.Runtime.CoreCLR": "1.0.2",
   "Microsoft.NETCore.DotNetHostPolicy":  "1.0.1",
   "MailKit" : "1.10.0"
 },
"frameworks": {
   "netstandard1.6": { }
 }
}

program.cs

using System;
using System.IO;  // for File.ReadAllText
using MailKit.Net.Smtp;   // for SmtpClient
using MimeKit;  // for MimeMessage, MailboxAddress and MailboxAddress
using MailKit;  // for ProtocolLogger

namespace sendHTMLemail
 {
     public class newsLetter
     {
         public static void Main()
         {
             var message = new MimeMessage();
             message.From.Add(new MailboxAddress("INFO", "[e-mail]"));
             message.To.Add(new MailboxAddress("MYSELF", "[e-mail]"));
             message.Subject = "Test Email";
             var bodyBuilder = new BodyBuilder();
             string htmlFilePath = "./html-files/msg.html";
             bodyBuilder.Attachments.Add("./html-files/msg.html");
             bodyBuilder.HtmlBody = File.ReadAllText(htmlFilePath);
             message.Body = bodyBuilder.ToMessageBody();

            using (var client = new SmtpClient (new ProtocolLogger ("smtp.log")))
            {
                   client.Connect("smtp.office365.com", 587);
                   try{
                       client.Authenticate("[e-mail]", "inof@PSWD");
                   }
                   catch{
                       Console.WriteLine("Authentication Faild");
                    }

                    try
                       {
                       client.Send(message);
                    }
                    catch (Exception)
                        {
                             Console.WriteLine("ERROR");
                    }
                    client.Disconnect(true);
            }
       }
   }
 }

The above worked very fine, and the publish had been prepared running the below commands:

dotnet restore

dotnet build -r win10-x64
dotnet build -r win10-x86

dotnet publish -c release -r win10-x64
dotnet publish -c release -r win10-x86

but while executing the .exe file in the publish folder, it gave an error that the file pathTo/html-files/msg.html is not found.

Once I copied the folder required to the publish folder as below, everything worked fine:

NOTE If you do not need the public/static file to be seen by the user, then you can compress them, then read them from memory stream, as explained here
