I reinstalled Entity Framework and now it's giving error

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

Try to update your EntityFrame Work using this command from
update-Package EntityFramework

Also, make sure that the versions on packages.config and web.config match

C# ASP.NET MVC PayPal not finding assembly

I've installed PayPal using NuGet Install-Package PayPal
I'm then using the code from here to test: https://devtools-paypal.com/guide/pay_paypal
Dictionary<string, string> sdkConfig = new Dictionary<string, string>();
sdkConfig.Add("mode", "sandbox");
string accessToken = new OAuthTokenCredential("XXXXXXXXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXXXXXXXXXX", sdkConfig).GetAccessToken();
I've put a breakpoint after this to inspect, but when I load up the page i get:
Could not load file or assembly 'PayPal, Version=1.7.3.0, Culture=neutral, PublicKeyToken=5b4afc1ccaef40fb' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Assembly Load Trace: The following information can be helpful to determine why the assembly 'PayPal, Version=1.7.3.0, Culture=neutral, PublicKeyToken=5b4afc1ccaef40fb' could not be loaded.
Any help on how to resolve this?
EDIT
I've tried the answers from the link given to the possible duplicate and none of them work for me.

I've just copied my code into a new solution and it's worked. The only thing I can think of is that it's because I named the solution 'PayPal' and this caused an issue somewhere.

Getting Error While Debugging the Plugin in dynamics crm 2013

I'm getting below error while debugging the plugin.
Unhandled Exception: System.IO.FileLoadException: Could not load file

It is a CRM 2013 online instance.

Can you check what version of Microsoft.Xrm.Sdk.Workflow library you have referenced in your project. According to the error message, CRM is looking for the Version=6.0.0.0.
