title: How to make an external assembly available at runtime?
body: <p>I asked a question <a href="https://stackoverflow.com/questions/4594968/how-to-add-types-from-external-assembly-to-toolbox-control-wpf">here</a> and apparently the problem is where I can load an assembly using Reflection's <code>Assembly.LoadFile</code> or <code>Assembly.LoadFrom</code>, and get the type inside that assembly, the assembly is still not accessible in the whole application. So when WPF tries to resolve a type, it doesn't find that type because it doesn't find the assembly. </p>
  
  <p>My question is, can I reference an assembly at runtime, so that it will be resolvable by WPF?</p>
