Having successfully passed this exam second time around and having had some time to reflect on it I thought I would post some useful links and resources for fellow devs who may be sitting this exam.
I cannot go into the content of the exam and tell you about it but I will post the links I used to study for the exam below.
Ok onto the content and links I used to help me pass the exam, dont worry if the content looks for an older exam as this is all relevant:- (The hardest part iof the exam for me was the WCF part of the exam.)
