Custom Content Pipeline with Automatic Serialization Load Error
- by Direweasel
I'm running into this error:
Error loading "desert". Cannot find type TiledLib.MapContent,

When trying to run the game. This is a basic demo to try and utilize a separate project library called TiledLib. I have four projects overall:
TiledLib (C# Class Library)
TiledTest (Windows Game)
TiledTestContent (Content)
TMX CP Ext (Content Pipeline Extension Library)
TiledLib contains MapContent which is throwing the error, however I believe this may just be a generic error with a deeper root problem.
EMX CP Ext contains one file: MapProcessor.cs

TiledLib contains a large amount of files including MapContent.cs
using System;
using System.Collections.Generic;
using System.Globalization;

public MapContent(XmlDocument document, ContentImporterContext context)
{
XmlNode mapNode = document["map"];
Version = mapNode.Attributes["version"].Value;

{

}
foreach (XmlNode tileSet in document.SelectNodes("map/tileset"))
{
if (tileSet.Attributes["source"] != null)
{
TileSets.Add(new ExternalTileSetContent(tileSet, context));
}
else

}
}
foreach (XmlNode layerNode in document.SelectNodes("map/layer|map/objectgroup"))
{

if (layerNode.Name == "layer")
{

}
else if (layerNode.Name == "objectgroup")
{
layerContent = new MapObjectLayerContent(layerNode, context);
}
else
{
throw new Exception("Unknown layer name: " + layerNode.Name);
}
// Layer names need to be unique for our lookup system, but Tiled
// doesn't require unique names.
string layerName = layerContent.Name;
int duplicateCount = 2;
// if a layer already has the same name...
if (Layers.Find(l => l.Name == layerName) != null)
{
// figure out a layer name that does work
do
{
layerName = string.Format("{0}{1}", layerContent.Name, duplicateCount);
duplicateCount++;
} while (Layers.Find(l => l.Name == layerName) != null);
// log a warning for the user to see
context.Logger.LogWarning(string.Empty, new ContentIdentity(), "Renaming layer \"{1}\" to \"{2}\" to make a unique name.", layerContent.Type, layerContent.Name, layerName);
// save that name
layerContent.Name = layerName;
}
Layers.Add(layerContent);
}
}
}
}
I'm lost as to why this is failing. Thoughts?
-- EDIT --
After playing with it a bit, I would think it has something to do with referencing the projects. I'm already referencing the TiledLib within my main windows project (TiledTest). However, this doesn't seem to make a difference. I can place the dll generated from the TiledLib project into the debug folder of TiledTest, and this causes it to generate a different error:

This is all incredibly frustrating as the demo doesn't appear to have any special linking properties. The TiledLib I am utilizing is from Nick Gravelyn, and can be found here: https://bitbucket.org/nickgravelyn/tiledlib.
The demo it comes with works fine, and yet in recreating I always run into this error.
