C# compiler allows me to write :
int k=new Int32();
However , I can't assign any value to it.
2 questions
1) doesnt new create a Heap allocation , and if so , what about the stack<->value thing ?
2)I can't do nothing with int k=new Int32();. in what scenarios will I use it ?

Int32 is an immutable value type that represents signed integers with values that range from negative 2,147,483,648 (which is represented by the Int32. MinValue constant) through positive 2,147,483,647 (which is represented by the Int32. MaxValue constant. .
In C#, Int32 Struct represents 32-bit signed integer(also termed as int data type) starting from range -2,147,483,648 to +2,147,483,647. It also provides different types of method to perform various operations. You can perform the mathematical operation like addition, subtraction, multiplication, etc. on Int32 type.
Int32 is a type provided by . NET framework whereas int is an alias for Int32 in C# language.
Int32 is 32 bit, while int is 64 bit; int is 32 bit integer on 32 bit platform, while it is 64 bit on 64 bit platform; int is value type, while System.
All structs (and int/Int32 is a struct) allow new() usage, which just means: initialise the struct to default values, I.e. zero for all fields in the struct. Most structs are immutable - and primitives certainly are. Basically, what you have written is the same as:
int k=0;
You can do lots of things with that.... But you can't change any properties of zero. Zero is zero is zero.
new does not always mean "allocate on the heap".
