ASP.NET Identity and IdentityServer connection
<p>Can somebody explain the connection between Identity and IdentityServer?</p>

<p>There was a recent article that says there will be a new version of IdentityServer (ie IdentityServer 4). </p>

<p>I'm doing a ASP.NET 5 project. I only heard of Identity 3 before and I'm planning to use it. </p>

<p>Can I use Identity 3 in my project without using this IdentityServer?</p>
