please suggest me doing wrong. thanks.

the error being caused view defining section, i.e.:

@section title { ... } 

but, section never utilized. can mean particular view not utilize default.cshtml layout, implement section. you'll need figure out why it's not utilizing layout think should be. here's few things for:

1. unless, set layout in view, layout uses determined closest _viewstart.cshtml file. razor first in same folder view in question , walk views directory tree there. check , _viewstart.cshtml files in tree.

2. if you're utilizing layout inheritance, must remember redefine sections in each layout. example, if following:

   default.cshtml

   @rendersection("title", required: false) 

   sublayout.cshtml

   @{ layout = "~/views/shared/default.cshtml"; } 

   view.cshtml

   @{ layout = "~/views/shared/sublayout.cshtml"; } @section title { ... } 

   you error sublayout.cshtml not implement section. redefine it, need add following sublayout.cshtml:

   @section title {     rendersection("title", required: false) }
