following project.json file

{   "dependencies": {     "microsoft.netcore.app": {       "version": "1.0.0",       "type": "platform"     },     "microsoft.aspnetcore.diagnostics": "1.0.0",     "microsoft.aspnetcore.server.iisintegration": "1.0.0",     "microsoft.aspnetcore.server.kestrel": "1.0.0",     "microsoft.extensions.logging.console": "1.0.0",     "microsoft.aspnet.iisplatformhandler": "1.0.0-rc1-final",     "microsoft.aspnet.server.kestrel":"1.0.0-rc1-final",     "microsoft.aspnet.mvc": "6.0.0-rc1-final",     "microsoft.aspnet.mvc.core": "6.0.0-rc1-final"   },    "tools": {     "microsoft.aspnetcore.server.iisintegration.tools": "1.0.0-preview2-final"   },    "frameworks": {     "netcoreapp1.0": {       "imports": [         "dotnet5.6",         "portable-net45+win8"       ]     }   },    "buildoptions": {     "emitentrypoint": true,     "preservecompilationcontext": true   },    "runtimeoptions": {     "configproperties": {       "system.gc.server": true     }   },    "publishoptions": {     "include": [       "wwwroot",       "web.config"     ]   },    "scripts": {     "postpublish": [ "dotnet publish-iis --publish-folder %publish:outputpath% --framework %publish:fulltargetframework%" ]   } }

following startup.cs file

using system; using system.collections.generic; using system.linq; using system.threading.tasks; using microsoft.aspnet.builder; using microsoft.aspnetcore.hosting; using microsoft.aspnetcore.http; using microsoft.extensions.logging; using microsoft.extensions.dependencyinjection;  namespace poc {     public class startup     {         // method gets called runtime. use method add services container.         // more information on how configure application, visit http://go.microsoft.com/fwlink/?linkid=398940         public void configureservices(iservicecollection services)         {             services.addmvc();         }          // method gets called runtime. use method configure http request pipeline.         public void configure(iapplicationbuilder app)         {             app.usemvc( m=>              m.maproute(                 name:"default",                 template:"{controller}/{action}/{id?}",                 defaults:new { controller="home", action="index"}                 ));         }     } }

i error @ service.addmvc() line in startup.cs file please suggest solution this.

have tried using dependency mvc in project.json:

"microsoft.aspnetcore.mvc": "1.0.0"

instead of these?

"microsoft.aspnet.mvc": "6.0.0-rc1-final", "microsoft.aspnet.mvc.core": "6.0.0-rc1-final"

it's possible using aspnetcore aspnet mvc dependencies leads conflicts.
