Answer 1

These problems occur when you are working with older .net version and trying to build with the latest IDE

It depends on which version of IDE you are using and also the current code version.

Check the web config,

In my case, I was using the Latest version i.e 4.7 and directoryService assembly are still referring to C#4.0.

Add below if you are using Latest version of id i.e 4.7
