Run CSC.exe from command line using Batch File

Question

I am using the following batch script code to compile c# code but what I see is a black window (csc.exe) flashes and I can not see the exe file created.

start /wait C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe /out:aa.exe Program.cs
start aa.exe
pause

I want to create the file aa.exe at the same location as Program.cs

Basically what I want is to dynamically compile the code in Program.exe and run it. I am

using this following references:  
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Threading;
using System.Net.Mail;

Here's more info on the subject: Command-line Building With csc.exe — Jeremy Thompson

Don't forget to add the references in the command:

/reference:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\<dotnet_version>\Microsoft.CSharp.dll" /reference:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\<dotnet_version>\mscorlib.dll" /reference:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\<dotnet_version>\System.Core.dll" /reference:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\<dotnet_version>\System.dll"

Rather than using start to launch the program, consider cmd. If you use cmd /K it should stay open after the command runs, giving you time to inspect the output.

Use:

csc.exe /out:StackBackTraceOrRT_FATAL.exe StackBackTraceOrRT_FATAL.cs

Or you want use `CSharpCodeProvider?

No I dont want to use any precompiled code. I want to compile on the fly and execute it.

@AkshayJ: See MSDN what can do CSharpCodeProvider. It is the programmable wrapper against C# Compiler to compile a code from string and generate an assembly, both on disk or in memory. And execute by demand.
