The following error message appears if you define a member template class or function outside the class:
error C2059: syntax error : ''template<''
error C2065: 'T' : undeclared identifier


The compiler does not support out-of-class definition of member template functions and classes. Please refer to the C++ Standard, section 14.5.2, for information on member templates.


Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.


Steps to Reproduce Behavior

The following code example demonstrates the error:
// compiler option needed: none

template<class T> class string {
	template<class T2> int compare(const T2&);
	template<class T2> string(const string<T2>& s) {}  // inline definition OK 
	//  ...
template <class T> template<class T2> int string<T>::compare(const T2& s)
				// error C2059 and C2065 
	//  ...		// Out-of-class-definition
