Reference old library from Asp.NET 5 -

i'm trying add vanilla class library (classlibrary1, built .net 4.6.1 although have tried 4.5.1) asp.net 5 web project(1.0.0-rc1-update1, though i've tried 1.0.0-rc1-final too) both part of same solution.

i tried usual add reference vs, doesn't work. this:

i tried using dnu wrap this:

dnu wrap classlibrary1\classlibrary1.csproj 

this generated following project.json:

{   "version": "1.0.0-*",   "frameworks": {     "net461": {       "wrappedproject": "../../classlibrary1/classlibrary1.csproj",       "bin": {         "assembly": "../../classlibrary1/obj/{configuration}/classlibrary1.dll",         "pdb": "../../classlibrary1/obj/{configuration}/classlibrary1.pdb"       }     }   } } 

i added asp.net 5 project.json

  "frameworks": {     "dnx451": {       "dependencies": {         "classlibrary1": "1.0.0-*"       }     },     "dnxcore50": {       "dependencies": {         "classlibrary1": "1.0.0-*"       }     }   } 

when restore packages, error

nu1002 dependency classlibrary1 1.0.0 in project webapplication1 not support framework dnx,version=v4.5.1.

i can't add namespace or anything.

i tried more sensible approach of targeting net461

  "frameworks": {     "net461": { "dependencies": { "classlibrary1": "1.0.0-*" } },     "dnx451": { "dependencies": { } },     "dnxcore50": { "dependencies": { } }   } 

on surface seems working won't build minute classlibrary1 referenced.

if remove dnx frameworks, build won't work when try debug it. error message

the program '[9328] dnx.exe' has exited code 1 (0x1). program '[15060] iisexpress.exe' has exited code -1 (0xffffffff). 

i have tried , went far hardcoding paths no avail

"frameworks": {     "net461": { "dependencies": { "classlibrary1": "1.0.0-*" } },     "dnx451": {       "bin": {         "assembly": "../../classlibrary1/obj/{configuration}/classlibrary1.dll",         "pdb": "../../classlibrary1/obj/{configuration}/classlibrary1.pdb"       }     }   } 

is there way of doing this?

i must missing something...
