title: Entity Framework 7 and login failed
body: <p>I'm trying to work with ef7 and asp.net mvc 6, but when i try to work with db there comes following exceptions:</p>
  
  <blockquote>
    <p>Cannot open database "Posts" requested by the login. The login failed.</p>
    
    <p>Login failed for user 'alexpc\Alexandr'.</p>
  </blockquote>
  
  <p>In DbContext class  i use following code:
  </p>
  
  <pre><code>protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
  {
      optionsBuilder.UseSqlServer(@"Data Source=alexpc;Database=Posts;Integrated security=True;");
  }
  </code></pre>
  
  <p>It seems like ConnectionString is right, where can there be the problem?</p>
