Whats the cause of error value cannot be null. Parameter name:key in vs2012 RRS feed

  • Question

  • I just installed the update 3 on vs2012 (win 8 64bit pc) and started a new project to do. I didnt add anything to the project but just tried to run it when the above error was raised! It is in line 0,column 0! The most unclear error ever. What is the cause?

    I played around with the Configuration Manager but nothing changed. There were Any Cpu,x64,x86 and release/debug options. Should I have seen emulators such as "ARM" there? (I saw that in one screenshot taken by users online).

    What am i missing?

    P.S. the xamll works fine. I can even enter the code enter no problem. I just want to know whats the error for?
