How to use CSharpCodeProvider in windows standalone?

Hello,

I try to dynamically compile C# code during execution with CSharpCodeProvider.
It work fine in unity Editor but not in windows standalone
My code is :

		CSharpCodeProvider provider = new CSharpCodeProvider();
		string source = "using System;" +
						"public class MyClass" +
						"{" +
						"   public MyClass ()"+
						"   {" +
						"   }" +
						"   public static string log()"+
						"   {"+
						"      return \"MyClass.log()\";"+
						"   }"+
						"}";


		CompilerParameters cParameters = new CompilerParameters();
		cParameters.ReferencedAssemblies.Add( "System.dll" );
		cParameters.GenerateExecutable = false;
		cParameters.OutputAssembly = "test.dll";
		CompilerResults cResults = provider.CompileAssemblyFromSource(cParameters, source);
    
		if (cResults.Errors.HasErrors)
		{
			foreach (CompilerError ce in cResults.Errors)
				Debug.LogWarning ("Errors building :" + ce.ToString ());
		} else if (cResults.Errors.HasWarnings)
		{
			foreach (CompilerError ce in cResults.Errors)
				Debug.LogWarning ("Warning building :" + ce.ToString ());
		} else
		{
			Assembly assembly = cResults.CompiledAssembly;
			System.Type type = assembly.GetType("MyClass");
			Debug.LogWarning( (string) type.InvokeMember("log", BindingFlags.InvokeMethod, null, assembly, null));
		}

And I have this error when I use windows standalone:

FileNotFoundException: Windows mono path not found: C:\Users\guillaume\Stage\Projects\GUI3\mono\mono\mini\mono.exe

Anyone having this problem?
