C# Code compiled .exe doesn't run

Question

I am using the CSharpCodeProvider in order to compile an .exe myself with variable parameters. Compiling works fine (doesn't return errors) and succeeds but when running it starts and instantly quits w/o any error or output. When changing the "Main" (e.g. to private or by renaming it) the compiler outputs that there is no valid Main Method, so the sample code shouldn't be the reason.

Does anyone have an answer/solution to this? I'm pretty lost on this one and would appreciate any helpful response. Thanks in advance ~

Compiler:

using System;
using System.CodeDom.Compiler;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Resources;
using System.Security.Cryptography;
using System.Text;
using Microsoft.CSharp;
using Packer.Properties;

namespace Packer
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            Console.WriteLine("Sample Compiler");
            Console.WriteLine(".ico-path: ");
            var icon = "E:\\sample.ico"; //Console.ReadLine();
            Console.WriteLine("> " + icon);
            Console.WriteLine("Target-exe: ");
            var target = "E:\\sample.exe"; //Console.ReadLine();
            Console.WriteLine("> " + target);
            var source = Resources.samplesource;
            // Compile with all params
            var success = CompileFromSource(source, target, icon);

            Console.WriteLine(success ? "Successfully compiled." : "Compiling error.");
            if (success) Process.Start(target);

        }

        private static bool CompileFromSource(string source, string output,
string icon = null, string[] resources = null)
        {
            var cParams = new CompilerParameters
            {

            cParams.TreatWarningsAsErrors = false;
            cParams.ReferencedAssemblies.Add("System.dll");
            cParams.ReferencedAssemblies.Add("System.Core.dll");
            cParams.ReferencedAssemblies.Add("System.Data.dll");

                foreach (var res in resources)
                {
                    // Add each resource file to the compiled stub.
                    cParams.EmbeddedResources.Add(res);
                }
            }
            // Dictionary variable is used to tell the compiler what we want
            var providerOptions = new Dictionary<string, string> {{"CompilerVersion", "v4.0"}};
            var results = new CSharpCodeProvider(providerOptions).CompileAssemblyFromSource(cParams, source);
            // Check if any errors occured while compiling.
            if (results.Errors.Count <= 0) return true;
            Console.WriteLine("The compiler has encountered {0} errors", results.Errors.Count);
            foreach (CompilerError err in results.Errors)
            {
                Console.WriteLine("{0}\nLine: {1} - Column: {2}\nFile: {3}", err.ErrorText, err.Line, err.Column,
                    err.FileName);
            }
            return false;
        }
    }
}

The code to compile:

using System;
using System.Text;

namespace CC2Runner
{
    public static class Program
    {
        public static void Main(string[] args)
        {
            try
            {
                Debug.WriteLine("Sample Starting...");
                Console.WriteLine("Sample Starting...");
                ...
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
            }
            Console.ReadLine();
        }
    }
}

You've made a WinForms program.

This does not have a console, nor does it output anything to the console it was started from.

How do I know? This:

var options = "/optimize+ /platform:x86 /target:winexe /unsafe";
                                        ^^^^^^^^^^^^^^

Which from csc:

 /target:exe                   Build a console executable (default) (Short
                               form: /t:exe)
 /target:winexe                Build a Windows executable (Short form:
                               /t:winexe)

Switch to /target:exe instead and it should work much better.
