Binding RadioButtons with Gender Property in WPF Using Value Converter

Many WPF developers face a common problem when working with RadioButtons . They try to bind RadioButtons with a Gender property, but the binding does not work as expected . Why does this happen?

Difference between object,var, dynamic in C#

1. object,var,dynamic can store any type of value.object and dynamic no need to initilize at the time of declaration but var should be initilize at the time of declaration.
2. object is not type safe because compiler
has little information about type.
dynamic is not type safe because compiler does not have any information about type.
var is type safe beacuse compiler have all information about stored value.
3. object and dynamic can be passed as method arguments and also a method can return object ,dynamic type.
but var can't be pass as method arguments and also no method can return var type.
