title: How to connect from .NET .dll file to Azure using Linked Service
body: <p>I want to write a code, similar to the code at the bottom of this link (<a href="https://azure.microsoft.com/en-us/blog/automating-azure-analysis-services-processing-with-azure-functions/" rel="nofollow noreferrer">https://azure.microsoft.com/en-us/blog/automating-azure-analysis-services-processing-with-azure-functions/</a>) in Visual Studio and building a DLL file. However instead of using the connection string, i would like to use an existing Linked Service from my Azure portal.</p>
  
  <p>The goal is to create a DLL that refreshes my Cube, while at the same time using an existing Linked Service which is already in my Azure Portal.</p>
  
  <p>Is this possible?</p>
  
  <p>Thanks.</p>
