Issues with the auto generation of C# project in Unity

Scripting C# & .NET
1

I am using the Unity 5.2.2
Every time I click on the “Open C# Project” button on the menu, unity generates the Visual Studio solution and projects, and by default they are called “.CSharp.csproj”

My goal is to auto-modify the generated C# projects’ name by the Unity. For example change them from “trunk.CSharp.csproj” to “MyGame.CSharp.csproj”

I searched on the internet and found materials saying that if I derive a class from the AssetPostprocessor and create a static method OnGeneratedCSProjectFiles, then this method is going to be called by unity when the solution and projects are generated. In this way I can do whatever I can to the generated project and solution files.

So I created a class derived from the AssetPostprocessor and put it into the Editor folder under my project folder.
I tried clicking “Open C# projects” menu item but it seems that my method is not called by the unity.
I can tell that because if my test method is called then a text file is generated on the D drive.

using System.IO;
using System.Text.RegularExpressions;
using UnityEditor;

namespace Assets.Editor
{
    [InitializeOnLoad]
    class RXSolutionFixer : AssetPostprocessor
    {
        [MenuItem("My Editor Window/Test Fix Projects")]
        private static void TestFixProejct()
        {
            OnGeneratedCSProjectFiles();
        }

        private static void OnGeneratedCSProjectFiles() //secret method called by unity after it generates the solution
        {
            string currentDir = Directory.GetCurrentDirectory();
            string[] csprojFiles = Directory.GetFiles(currentDir, "*.csproj");

            var file = new StreamWriter("D:\\Test.txt");
            file.WriteLine("Good");
            file.Close();

//        foreach (var filePath in csprojFiles)
//        {
//            FixProject(filePath);
//        }
        }

        static bool FixProject(string filePath)
        {
            string content = File.ReadAllText(filePath);

            string searchString = "<TargetFrameworkVersion>v3.5</TargetFrameworkVersion>";
            string replaceString = "<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>";

            if (content.IndexOf(searchString) != -1)
            {
                content = Regex.Replace(content, searchString, replaceString);
                File.WriteAllText(filePath, content);
                return true;
            }
            else
            {
                return false;
            }
        }

    }
}

I don’t understand what I do wrong here, can anyone have a look and help me?
Actually the strange thing is that I successfully get the text file generated on D drive, but only once. And after that no matter how I modified my code it stopped working again.
