Figure 5shows snapshot of a typical fastcall stack frame stopped at a breakpoint at the "return smallObj;" line inside the Create method. (Fastcall is the .NET calling convention which specifies that arguments to functions are to be passed in registers, when possible, with all other arguments...
BLEManager is supposed to a singleton, right? So you want exactly one of these in your program. To ensure this, you should make the initializer private and access the BLEManager only through shared. But in the ContentView, you create a BLEManager without going through shared, so now you ...
