title: Connect to database in Visual Studio 2015
body: <p>This is going to be simple/stupid question.</p>
  
  <p>I have installed Visual studio 2015 Enterprise and created a class Library project with Framework 4.6. But I am not able to find [System.Data].</p>
  
  <p>I want to connect to SQL server using <code>SqlConnection</code> and <code>SqlCommand</code> like object. IntelliSense is not working. I am not able to find example on Google. Every example I have found is related to framework 4.0., but I am used to working with Visual Studio 2010.</p>

  <p>Update:

  Friends, I found that it was it was using project web-->Class library when I tried Windows-->Class Library project, it was all there. But still I want to know the difference....
  Now another problem is that I am not able to add reference this project in web project. It is giving some Dependency NewBLL>=1.0.0-* could not be resolved.</p>
