Can't Connect To Sql Server Database From Local Iis Over Https

I'm working on an application using ASP.NET MVC5 and connecting to my SQL Server database with SqlClient (Dapper.NET) I've been using Local IIS without a problem on http://localhos

Solution 1:

I know why this is...

It's a component available via NuGet called NCrypt which I've just spent 6 hours isolating.

I'm not sure how, but when it's present in my bin folder it interferes somehow with the handshake process between the code and SQL Server.

When it's removed, voila! SQL connects as expected.
