Executing remote Powershell commands from a Web page

I am .Net Developer, once i had task to make MVC UI interact with Microsoft Exchange server and manage Mailboxes of AD users, i had to learn powershell and how to interact with powershell through C#. So based on my experience i will advise you to start learning C# Using Console Application, understand how c# works with Powershell and AD and than start learning MVC to build an UI.

You should install System.management.Automation package from NuGet Package manager.

C# => Powershell (Execute Powershell Command) => Microsoft Exchange.

Simple Sample, getting user PrimarySmtpAddress attribute.

using System.Management.Automation;
using System.Management.Automation.Runspaces;

private static WSManConnectionInfo _connectionInfo;

static void Main(string[] args)
{
    string userName = "DOMAIN\\User";
    string password = "UserPassowrd";
    PSCredential psCredential = new PSCredential(userName, GenerateSecureString(password));

    _connectionInfo = new WSManConnectionInfo(
            new Uri("http://server.domain.local/PowerShell"),
            "http://schemas.microsoft.com/powershell/Microsoft.Exchange", psCredential);
    _connectionInfo.AuthenticationMechanism = AuthenticationMechanism.Kerberos;

    Console.WriteLine(GetPrimarySmtpAddressBy("Firstname Lastname");
}

public static string GetPrimarySmtpAddressBy(string identity)
    {
        using (Runspace runspace = RunspaceFactory.CreateRunspace(_connectionInfo))
        {

            using (PowerShell powerShell = PowerShell.Create())
            {
                powerShell.AddCommand("Get-Mailbox");
                powerShell.AddParameter("Identity", identity);
                runspace.Open();

                powerShell.Runspace = runspace;

                PSObject psObject = powerShell.Invoke().FirstOrDefault();

                if (psObject != null && psObject.Properties["PrimarySmtpAddress"] != null)
                    return psObject.Properties["PrimarySmtpAddress"].Value.ToString();
                else return "";
            }
        }
    }

public static System.Security.SecureString GenerateSecureString(string input)
    {
        System.Security.SecureString securePassword = new System.Security.SecureString();
        foreach (char c in input)
            securePassword.AppendChar(c);
        securePassword.MakeReadOnly();

        return securePassword;
    }
