Could not load file or assembly antlr.runtime

Question

I'm using MEF to add some parts to my ASP.net web application. I made a PoC project and everything works like a charm. But when I try to add it to my existing web app, I get the following error:

Could not load file or assembly 'antlr.runtime, Version=2.7.6.2, Culture=neutral, PublicKeyToken=1790ba318ebc5d56' or one of its dependencies. The system cannot find the file specified.

My project does not have any reference to antlr.runtime, and if I remove the MEF code it works fine.

var catalog = new AggregateCatalog();
catalog.Catalogs.Add(new DirectoryCatalog("bin"));
_container = new CompositionContainer(catalog);
var exports = _container.GetExports<HLResourceProviderFactoryBase>();

My DirectoryCatalog object successfully finds the assemblies where I want to get the Parts from.

Any hint on what could be the problem? Thanks in advance

You can use AssemblyInfo tool to see the dependency graph and find out what assembly depends on "antlr.runtime".
