When inheriting a class template, I get error c2760 in the constructor definition line, what is the error?

Question

C++ / C#

There are two class templates, the first is:
TypeSize.h
Code:
#pragma once
Code:

template <class T1>
class TypeSize
{
public:
  TypeSize(T1 value);
  ~TypeSize();
};

The second inherits from the first:
TypeInfo.h

Код:
#pragma once

template <class T1>
class TypeInfo : public TypeSize<T1>
{
public:
  TypeInfo(T1 value) : TypeSize<T1>(value); // тут получаю C2760 синтаксическая ошибка: ожидался токен "<Нет данных>", а не "<Нет данных>"
  ~TypeInfo();
};

Tell me what could be the problem.
Thanks in advance!

Answer 1

TypeInfo(T1 value) : TypeSize<T1>(value);

If this is an ad, then : TypeSize<T1>(value)there is no need. If this is a definition, then the body of the constructor should go
instead :;

TypeInfo(T1 value) : TypeSize<T1>(value)
{
}
