debugging - Microsoft.AspNet.Mvc.Core.pdb not loaded -

i have asp.net 5 , mvc 6 project has reference cl in same solution.

when try debug unable enter cl's breakpoints.

when come function calling cl , hit f11 continues , doesn't enter function debug.

when debug , on function of cl , choose "step specific" , choose function says :

microsoft.aspnet.mvc.core.pdb not loaded.  microsoft.aspnet.mvc.core.pdb contains debug information required find source module microsoft.aspnet.mvc.core.dll  module information     version : 6.00.0.10417    original location : <path in local disk>  try 1 of following options :    change existing pdb , binary search paths , retry:          microsoft symbbol servers 

so when try load microsoft symbol server says :

microsoft.aspnet.mvc.core.pdb not found in selected paths

my main project in mvc 6 , dll target framework : .net 4.5.2

i think due beta nature pdb files not on symbol servers. assume after rtm (remember vs rc asp.net 5 still beta) added symbol servers.

if need support before can clone asp.net mvc repository (https://github.com/aspnet/mvc.git) location outside project. in global.json (solution level file) add path project property. instruct compiler there dependency resolution. compiler attempt resolve dependency using local source on nuget package. in visual studio right click on references > restore packages. should see package icon change indicate source. can build, , step directly source.
