Unable to build solution in VSTS pipeline

Question

I am working on a service fabric solution and I am able to build and test the changes in my local machine whereas in VSTS pipeline and facing a minor issue saying that the interface method is not implemented.

If anyone of you face a similar issue, Can you guys suggest or help me out on how to fix or resolve this issue in the build pipeline.

Here is my scenario.

Interface

public interface IStudent
{
    void PrintFullName();
}

Base Class

public class BaseStudent
{
    public void PrintFullName()
    {
        // Implementation
    }
}

MainClass

public class Student : BaseStudent, IStudent
{
    public void PrintName()
    {
        // Implementation
    }
}
