Referencing external components will throw notfoundexception

Problem -
Adding a reference to a component in a project that is outside the scope of the project and not in the GAC will cause a notfound exception becuase it is not referenced within the Orchard.Web project.

How to reproduce -

1. Create A new project
2. Reference a component that is outside the scope of the project and not in the GAC
3. Create a .cs file in the newly created project, and put a using statement to the component in the .cs file.
4. run - You should see the bing error message below

Solution -

1. You could add the reference in to the Orchard.Web Project
   or
2. change the way BuildManager.GetReferencedAssemblies() works by going down the tree - A good article http://msdn.microsoft.com/en-us/magazine/cc163641.aspx
   I am part way to a solution for this, so once finished i will patch up.

There is a bigger problem to this really. If you dont reference the new project in orchard.web, you cant use that project. Am i right?

ErikPorter commented:

Correct, you have to reference the new project in Orchard.Web. That is the current design. It is temporary.

This will be addressed when we implement the module packaging/installation behavior.

Sorry if I'm not helping, but using the 0.1 release, you can use a project without rerferencing it from orchard.web. If you follow the instructions here: http://geekswithblogs.net/michelotti/archive/2010/04/22/create-orchard-module-in-a-separate-project.aspx you don't need to add a reference from WebPI --> Orchard.Widget. For a while. After a while you start seeing this bug. Which you can workaround by adding a reference from Orchard.WebPI to Orchard.Widget.

It looks like there's been LOADS of fixes since the 0.1 release, I'm really anxious to try a newer version of Orchard, but when I get the default branch code out of the repository, I can't add a module by following the walkthrough. Can anyone give me any pointers on how to create a module with the later (or latest) code? That'd be super-awesome.
