I am currently trying to port a game I am working on from XNA to Monogame, but I am having some trouble getting the content pipeline to cooperate. My game uses a number of XML files as XNB assets to represent objects in the game, which I created following the instructions [here](http://msdn.microsoft.com/en-us/library/ff604979.aspx). However, trying to move this across word-for-word into Monogame produces the following error:

> 
> An unhandled exception of type 'Microsoft.Xna.Framework.Content.ContentLoadException' occurred in MonoGame.Framework.dll
> 
> 
> Additional information: Could not load Parts\Window.xnb asset as a non-content file!
> 
> 
> 

Here is the class I have been using to define the content of the XML files:

```
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.Graphics;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;

namespace FileTypes
{
    public class PartFile
    {
        public struct State
        {
            public Rectangle[] frames;
            public int[] collision;
        }

        public Vector2 size;
        public string image;
        public string defaultState = "default";
        public bool fillBG;
        public int ticksPerFrame;
        public Dictionary<string, State> states;
        public string[] modules;
    }
}

```

Here is one of the XML files in the project:

```
<?xml version="1.0" encoding="utf-8" ?>
<XnaContent>
  <Asset Type="FileTypes.PartFile">
    <size>2 3</size>
    <image>Computer</image>
    <defaultState>default</defaultState>
    <fillBG>false</fillBG>
    <ticksPerFrame>7</ticksPerFrame>
    <states>
      <Item>
        <Key>default</Key>
        <Value>
          <frames>
            0 0 40 60
            40 0 40 60
          </frames>
          <collision>
            0 0
            0 0
            0 0
          </collision>
        </Value>
      </Item>
      <Item>
        <Key>active</Key>
        <Value>
          <frames>
            80 0 40 60
            120 0 40 60
          </frames>
          <collision>
            0 0
            0 0
            0 0
          </collision>
        </Value>
      </Item>
    </states>
    <modules>
      <Item>testModule</Item>
    </modules>
  </Asset>
</XnaContent>

```

And finally here is a sample of the code I use to load the file:

```
FileTypes.PartFile srcPart = content.Load<FileTypes.PartFile>("Parts\\" + name);

```

Does anybody know what I need to do in order to get my code working in Monogame? I've been looking around the internet for a fair while, but so far I've yet to find a solution to my issue. Alternatively, if I've been going about the entire system wrong all this time and there's a far easier way to handle what I want to do, I'd love to hear it.

Thanks in advance!
