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?
