In C# why can't a conditional operator implicitly cast to a nullable type

I am curious as to why an implicit cast fails in...

int? someValue = SomeCondition ? ResultOfSomeCalc() : null;

and why I have to perform an explicit cast instead

int? someValue = SomeCondition ? ResultofSomeCalc() : (int?)null;

It seems to me that the compiler has all the information it need to make an implicit casting decision, no?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
