Accessing a Class that is NOT declared in App_Code in ASP.NET
<p>I sometimes define Business Logic classes to "help" my ASPX code-behind classes.  It makes the most sense to me to include them both in the code-behind file since they work together.  However, I'd occasionally like to access the Business Logic classes from higher level classes defined in App_Code but they aren't automatically accessible outside of the file.</p>

<p>Thus, the question: it is easy to access classes defined in App_Code but how do I access classes defined elsewhere?</p>

<p>UPDATE: One other thing, the ASPX page class and the App_Code class are in the same namespace - that isn't the issue.</p>

<p>NOTE: I have taken the advice of those who have responded (thanks guys) and am refactoring to make class access easier.  However, I don't think the question is actually answered yet (in the case of an ASP.NET Website project).  I don't <em>need</em> the answer any more but, if someone could clarify what makes classes visible when they are outside of App_Code, it may well help someone else (or even me, down the road).</p>
