Is it possible? (Visual studio resources in a wpf or a windows forms program or even an asp.net application)

I had this idea: create a program that simulates the visual studio to help people learn c#. It would be something like that "try for yourself" feature of w3schools.com

There would be a textbox that the user could put some code in it for example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
        }
    }
}

but now there's the tricky part: if the user commited a synthax error for example, i'd like to show the error like the visual studio, or when the user clicks on a "verify" button, if the code is wrong, i'd get the same error as the visual studio would show up. Is it possible?

Thanks for the answers. I've found what i've been looking for. What i wanted to do, is to allow an user to input some code in a text box, and when he/she clicks on a "generate" button, the code would be compiled and an .exe would be generated. After some research, ive found this class:

CSharpCodeProvider codeProvider = new CSharpCodeProvider();

You can set some parameters to generate an .exe or a dll and you send a string as the code to be compiled. If it has errors, you can catch them by doing this:

 if (results.Errors.Count > 0)
{
                {
                    foreach (CompilerError CompErr in results.Errors)
                    {
                        txtErro.Text = txtErro.Text +
                            "Line number " + CompErr.Line +
                            ", Error Number: " + CompErr.ErrorNumber +
                            ", '" + CompErr.ErrorText + ";" +
                            Environment.NewLine + Environment.NewLine;
                    }
                }
}

I hope that this can be useful to the others as well. Thanks a lot!

I think it is possible but you have to use reflection. With that you can dynamically create C# code which you can compile runtime. It is however quite advanced but as far as I know it is possible.

The following link might be useful:

Generating DLL assembly dynamically at run time

What you really want is:

What are the benefits of Compiler as a Service

But afaik this is not available now. Also you do not get the debugging functionality. You can probably run a new instance of VS with debugging etc, but it might be a little overkill.
