I have just pushed my latest project live for the group ST220 ENTHUSIASTS.
It is a mobile friendly Umbraco CMS based website, the front end has been written using Bootstrap, jQuery, Now UI, AJAX and the Razor template engine.
The underlying code is the Umbraco CMS system which runs on Dot Net Framework 4.7 (C#).
Some of the code i used in the site has come from a really useful resource codeshare.co.uk
The site can be found here: https://st220enthusiasts.com
I came across an issue after updating my Visual Studio version to 15.5.3 which would cause my solution to throw an exception whenever it tried to access the database.
System.IO.FileLoadException: 'Could not load file or assembly 'System.Data.SqlClient, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)'
The fix for this is nice and easy, you just need to install the NuGet (V4.4.2) package System.Data.SqlClient.
