title: start with SimpleMembership in MVC 4 within visual studio 2012
body: <p>I am creating web app in MVC 4 that is require custom Login, authentication and role based system. My intention is to use SimpleMembership and SimpleRole but struggling to start with and grasp its basic implication within my app. </p>
  
  <p>I have already database say for example DB1.mdf and have created Users table with userId and UserName. I believe i need to initialize simplemembership with existing database??? and i dont want system create database itself if it doesn't find, as it is doing in default internet template created by visual studio 2012. </p>
  
  <p>many thanks in advanced... </p>
