put the actual error text in the question, not a screenshot - makes it a pain to copy/paste. Besides the error message tells you one of the ways to fix the error. — user1666620, Oct 29 '15 at 11:45
first result on google for the error message http://stackoverflow.com/questions/31868803/error-invalid-option-6-for-langversion-must-be-iso-1-iso-2-3-4-5-or-defa — user1666620, Oct 29 '15 at 11:46

maybe this is the solution: change the compiler version in the web.config

web config compiler version

If you see at the bottom of your error message

Asp.net version is 4.6 .net framework is 4.0

Make sure you're compiling in correct framework.

amit thank ... I believe is a bug issue as this code was original done in VS2013 and now being coded on VS2015 can you advise I have changed target framework: 4.6 language version to 6 still errors – Jaz Bansal Oct 29 '15 at 12:22
can you share compiler tag from your web.config? – amit dayama Oct 29 '15 at 12:40
thanks I have managed to sort this out, I created a new web.config file with the correct .net framework version – Jaz Bansal Oct 29 '15 at 16:22
