Why can’t compiler detect at compile-time that obj references object of type B and thus reports an error when we try to cast it to type A ?
public class A { } public class B { } static void Main(string[] args) { B b = new B(); object obj = (object)b; ...

You want the compiler to follow the control flow, and determine ahead of time that the cast will cause an exception? Why bother? With a real program, the control flow will be too complicated to figure this out .

Essentially because the initialisation of the variable would be skipped if the label containing the variable initialisation was not hit .

Have a look through your code to see if SqlCeCommand is used anywhere .
Try on an emulator and/or closing some apps first.
It's possible either the 'sqlceme30.dll' is missing or maybe you're out of Virtual Memory and the DLL can't be loaded .

Did you declare your NSUinteger as a Property (@property in the interface & @synthesize in the .m-file?) also make sure that you copy the values instead of passing it as a reference
->@property (readwrite, copy) NSUInteger *yourInt;
maybe this helps... .

Aproach it differently, as far as I can tell your code is something like:
NSNumber *aNumber = [anArray objectAtIndex:index.row]; unsigned long = aNumber;
In stead of using a unsigned long you should use a NSUinteger btw .

8084143463 == 0x1e1da3d67 3789176167 == 0x0e1da3d67
The size of a long on a 64bit system is 8 bytes .
Your value is larger than the maximum value an unsigned long can hold (2^32 - 1 == 4,294,967,295) in 32-bit mode .

Use standard
int main(int argc,char **argv)
You would run the program with the IP or Hostname of the server you want to connect to .
If I not mistake, you are trying to use UNICODE string -- tchar .
