title: Deploying custom dll's in SharePoint 2010
body: <p>I'm new to SharePoint and trying to get my head around this.  I have a simple Web Part project.  I also have a custom Data layer project that uses the Microsoft Enterprise Library for data access.  In the Web Part project, I am adding a reference to the Data layer project's assembly.  I specified in the Package of the Web Part project that I want my Data layer's assembly to be deployed.  I can verify this works by using standard ADO.NET classes and not the custom MS library.  If I deploy to the SharePoint server (which I have 100% access to) using the Enterprise Library, I get the error message:</p>
  
  <p>"Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary.Data"</p>
  
  <p>What steps do I need to take to ensure this project and all future projects on the server can easily gain access to the Enterprise Library for data access?</p>
  
  <p>Thanks!</p>
