vscode undefined reference issue

Question

I have three simple files that I have trouble compiling for some reason. When I use the terminal to compile the program (g++ .\main.cpp .\dynamic.cpp). I get this error message:

C:\Users\user1\AppData\Local\Temp\ccMPpwkX.o:main.cpp:(.text+0x4d): undefined reference to DynamicAr<int>::DynamicAr(int*, int)' C:\Users\user1\AppData\Local\Temp\ccMPpwkX.o:main.cpp:(.text+0x5a): undefined reference to DynamicAr::printAr()' collect2.exe: error: ld returned 1 exit status

main.cpp

#include "dynamic.h"

int main ()
{
    int arr[] = { 0, 1, 2, 3, 4 };
    DynamicAr<int> myArr(arr, 5);
    myArr.printAr();

    return 0;
}

dynamic.h

#ifndef DYNAMIC_H
#define DYNAMIC_H

#include <iostream>
#include <string>
using namespace std;

template <typename T>
class DynamicAr
{
private:
    T* dynamicAr;
    int size;

public:
    DynamicAr(T arr[], int size);
    void printAr();

};

#endif

dynamic.cpp

#include "dynamic.h"

template <typename T>
DynamicAr<T>::DynamicAr(T arr[], int size)
{
    dynamicAr = new T[size];
    this->size = size;
    
    for (int i = 0; i < size; i++)
    {
        dynamicAr[i] = arr[i];
    }
}

template <typename T>
void DynamicAr<T>::printAr()
{
    for (int i = 0; i < size; i++)
    {
        cout << *(dynamicAr + i) << endl;
    }
}

I have tried this exact code in Eclipse IDE and it works perfectly fine. I have also tried taking a look at the .json files but everything looks ok to me. The code should simply output the array contents.
