template compilation in .NET

Hi,
Is it not possible to have the method definitions of a template class in a separate src file, instead of defining everything in a single file in .NET?(Because you do not have an example doing this in the book)
If it is posible, why do i get an error C2995 for the following trivial code?
In file test.h

Code:

#ifndef TEST_H
#define TEST_H

template<typename T>
class test
{
public:
	test();
	~test();
	void setV(T i);
private:
	T value;
};
#include "test.cpp"
#endif

and in file test.cpp

Code:

#include"test.h"

template<typename T>
test<T>::test(){}

template<typename T>
test<T>::~test(){}

template<typename T>
void test<T>::setV(T i){value = i;}

Why do I get this? It is obvious that the methods are declared but not defined in the test.h

Thank you

Need to download code?
