I reinstalled Entity Framework and now it's giving error

Question

I initially got a problem in DB due to which I re-installed entity framework (earlier my version was 5.0 and now I installed 6.1.3), I am connected to SQL server but now I am getting an error which says:

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: An error occurred creating the configuration section handler for entityFramework: Could not load file or assembly 'EntityFramework, Version=6.1.3, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Please tell me how to resolve it. Thanks

check you web.config file for appropriate version of newly installed entity framework — Frebin Francis, Jul 21 '16 at 11:37
^ here's mine connection string , from where i can get new connection string for new EF? — Mah Mah, Jul 21 '16 at 11:40
the problem is not with connection string. it depends on which version of EF you set on the assemblyBinding — Frebin Francis, Jul 21 '16 at 11:42
and you should not expose your SQL connection account credentials anywhere — Frebin Francis, Jul 21 '16 at 11:43
check for entity framework version under runtime -> assemblyBinding config in web.config file — Frebin Francis, Jul 21 '16 at 11:44
can you post a screenshot of your web.config runtime -> assemblyBinding config section ? — Frebin Francis, Jul 21 '16 at 11:52
in runtime-> assemblyBinding where should i check? there's no EF field — Mah Mah, Jul 21 '16 at 11:54
can you please check anywhere in your project it's used EF config with 5.0 version ? — Frebin Francis, Jul 21 '16 at 11:58
