C# memory allocation: Difference between static class and a static instance

Question

How does CLR allocates memory in these 2 cases:
Are they both allocated in static memory area?

static class A 
{
    //Some methods
}

and

class A 
{
    //Some methods    
}
class B
{
    static A inst = new A();
    //Some methods
}

For the below statement, will the compiler

static A inst = new A();

allocate A in heap and assign it to static reference inst reference? Or it will create a static instance in High Frequency heap ?

Answer 1

Static fields are as any static fields, regardless if the class is static or static.

Static class is just a language tric to ensure that all members are static, nothing more. In .NET static classes do not even exists: A static class will be converted into a "normal" class with a private instance constructor. That way an instance of that class cannot be constructed.
