If your class is not static, you create a new instance of the class using the new() keyword, and store it in a variable. You can then use it through this variable. If your class is static, you can just use it directly since there is only one instance. Suggest you google how c# works with these things before you make everything static 😉

Be aware that VS Code is not really recommended for C#, but you can use it if you really want to. That said... C# isn't file based, so the compiler itself is fine with you using one or several files, it hardly cares at all. As Fused said, its very common to make a new file for each class you make

// in "Program.cs"
public static class Program
{
    public static void Main()
    {
        var data1 = GetDataFromProgram();
        var data2 = StaticClass.GetDataFromStaticClass();

        var normalClassInstance = new NormalClass();
        var data3 = normalClassInstance.GetDataFromNormalClass();
    }

    private static string GetDataFromProgram()
    {
        return "hello";
    }
}

// in "StaticClass.cs"
public static class StaticClass
{
    public static string GetDataFromStaticClass()
    {
        return "hello from a static class!";
    }
}

// in "NormalClass.cs"
public class NormalClass
{
    public string GetDataFromNormalClass()
    {
        return "hello from a normal class";
    }
}

// in "Program.cs"
public static class Program
{
    public static void Main()
    {
        var data1 = GetDataFromProgram();
        var data2 = StaticClass.GetDataFromStaticClass();

        var normalClassInstance = new NormalClass();
        var data3 = normalClassInstance.GetDataFromNormalClass();
    }

    private static string GetDataFromProgram()
    {
        return "hello";
    }
}

// in "StaticClass.cs"
public static class StaticClass
{
    public static string GetDataFromStaticClass()
    {
        return "hello from a static class!";
    }
}

// in "NormalClass.cs"
public class NormalClass
{
    public string GetDataFromNormalClass()
    {
        return "hello from a normal class";
    }
}
