I'm trying to make an editor window to ease my workflow of creating enemies. Most parts work fine apart from creating a class and adding it.

    void SaveAndCreate()
    {
       string guid = AssetDatabase.CreateFolder("Assets/Scripts/Enemies/EnemyTypes", enemyData.EnemyName);
        string newFolderPath = AssetDatabase.GUIDToAssetPath(guid);
        TextAsset templateTextFile = AssetDatabase.LoadAssetAtPath("Assets/CharacterTemplate.txt", typeof(TextAsset)) as TextAsset;

        string contents = "";
        if (templateTextFile != null)
        {
            contents = templateTextFile.text;
            contents = contents.Replace("CUSTOMCLASS_", enemyData.EnemyName.Replace(" ", ""));
        }
        using (StreamWriter sw = new StreamWriter(string.Format(newFolderPath + "/{0}.cs", new object[] { enemyData.EnemyName.Replace(" ", "") })))
        {
            sw.Write(contents);
        }

        objToCreate = new GameObject(enemyData.EnemyName);
        objToCreate.name = enemyData.EnemyName;
    }

Through this im creating the folders and class that i need which uses inheritance from a Monobehaviour. The objects name is the class, so if im making a "Dog" enemy the class that gets generated is "Dog.cs" which inherits from "Animals.cs". Now my issue lies with actually adding that class.

        //_go.AddComponent(Type.GetType(enemyData.EnemyName + ".cs"));//
        String ScriptName = objToCreate.name;
        Type MyScriptType = Type.GetType(ScriptName + "UnityEngine ,Assembly-CSharp");

        objToCreate.AddComponent(MyScriptType);
        AssetDatabase.SaveAssets();
        AssetDatabase.Refresh();   

As you can see i have tried a few things but since adding components through string is obsolete i cannot! I get this error "AddComponent asking for invalid type". So my question is is there any way for this to happen? I generate the dog.cs through script, create the prefab and assign to it through its name. This way i want to create enemies easy and adding all the necessary components automatically and not having to create each class on my own and assign in the editor. Thank you!
