Error Xml Deserialization XML (2, 2)

Question

I'm trying to read and deserialize the App.config XML to object, but i'm getting the following error:

An exception of type 'System.InvalidOperationException' occurred in System.Xml.dll but was not handled in user code

my code:

 AppConfigXML myclass = null;
 string configpath = "mypath";

 XmlSerializer serializer = new XmlSerializer(typeof(AppConfigXML));

 StreamReader reader = new StreamReader(configpath);
 myclass = (AppConfigXML)serializer.Deserialize(reader); //<- Error to deserialize

This is my App.config class to serialize and deserialize:

public class AppConfigXML
{   

        [XmlRoot(ElementName = "section")]
        public class Section
        {

have you looked for any working examples that are on Stackoverflow as well as the internet..? http://stackoverflow.com/questions/4123590/serialize-an-object-to-xml — MethodMan, Sep 09 '16 at 18:40
"This is my App.config class" Where? I can see here only many classes — Roman Marusyk, Sep 09 '16 at 18:46
1) Can you share the XML file that generates the error? 2) What is the full `ToString()` output of the exception including the exception type, message, traceback, and **`InnerException`** if any? The inner exception often gives useful details for `XmlSerializer` exceptions. — dbc, Sep 09 '16 at 19:08
Your type `AppConfigXML` class has no [properties](https://msdn.microsoft.com/en-us/library/x9fsa0sw.aspx) or [fields](https://msdn.microsoft.com/en-us/library/ms173118.aspx)! It only has some [nested types](https://msdn.microsoft.com/en-us/library/ms173120.aspx). Thus there is nothing to serialize. — dbc, Sep 09 '16 at 19:09
Here's a [fiddle](https://dotnetfiddle.net/O1OBey) demonstrating that your `AppConfigXML` has no actual properties or fields. — dbc, Sep 09 '16 at 19:19
@MarioGuadanhim I see it now. Thanks that updated the question — Roman Marusyk, Sep 09 '16 at 19:58
