How to handle both a single item and an array for the same property using JSON.net
...t will know to use the custom converter for that property. I would also recommend using [JsonProperty] attributes so that the member properties can be given meaningful names independent of what is defined in the JSON.

Why does an NSInteger variable have to be cast to long when used as a format argument?
...
You get this warning if you compile on OS X (64-bit), because on that platform NSInteger is defined as long and is a 64-bit integer. The %i format, on the other hand, is for int, which is 32-bit. So the format and the actual parameter do not match in si...

How do I Moq a method that has an optional argument in its signature without explicitly specifying i
...you only have a single point of change. If you really want to, you can overcome Moq's apparent short-coming here by duplicating Foo's parameters into this initialisation function:
public void InitFooFuncOnFooMock(Mock<IFoo> fooMock, string a, bool b = false)
{
if(!b)
{
fooMock...
Why do function pointer definitions work with any number of ampersands '&' or asterisks '*'?
...
There are a few pieces to this that allow all of these combinations of operators to work the same way.
The fundamental reason why all of these work is that a function (like foo) is implicitly convertible to a pointer to the function. This is why void (*p1_foo)() = foo; works: ...
How to inspect the return value of a function in GDB?
