  ## <a id='use'></a>Use Extension Buildpack to Add DLLs to .NET Framework Apps
  
  Most .NET Framework apps are pushed with the [Hosted Web Core (HWC) buildpack](../hwc/index.html).
  The HWC buildpack contains an opinionated list of .NET dependencies and does not contain all the
  DLLs that every app could need.
  
  If your app requires dependencies not contained in the HWC buildpack, we recommend that you create
  an extension buildpack. This extension buildpack references and supplies these dependencies to the
  container for the app when you push the app.
  
  <p class='note'><strong>Note:</strong> You cannot add modules or extensions directly to HWC. HWC
  contains a number of built-in HWC features, like the URL Rewrite module and HTTP compression.
  Extensions should only provide additional functionality to your app. For more information about
  existing HWS features, see <a href="../hwc/index.html#features">Features</a> in
  <em>HWC Buildpack</em>.</p>
  
  To DO SOMETHING, follow the steps below:
  
  1. Create a list of the dependencies that your published app requires.
  
  
negative.code: ## <a id='combine'></a>Combine Extension Buildpack with Other Features
  
  If your extension buildpack has executables or scripts that need to be run, you can reference them
  either in the start command or in profile scripts.
  
  * For more information about the start command, see
  [command](../../devguide/deploy-apps/manifest.html#start-commands) in <em>Deploying with Application Manifests</em>.
