title: How do I use external assemblies with Microsoft Azure Function Apps?
body: <p>The <a href="https://azure.microsoft.com/en-us/documentation/articles/functions-reference-csharp/" rel="noreferrer">documentation</a> says that you can put a DLL in a <code>bin</code> folder and reference it using a special <code>#r</code> syntax, however in the Azure portal I cannot find how to upload these DLLs. Is this possible, and if so, how is that supposed to be accomplished?</p>
