I got it to work using code like the following (thanks to Prabhakantha). I had to use a timer to set the cursor after handling the textbox Enter event:

    private void textBox1_Enter(object sender, EventArgs e)
    {
        timer1.Enabled = true;
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        timer1.Enabled = false;
        CreateCaret(textBox1.Handle, IntPtr.Zero, 6, textBox1.Height);
        ShowCaret(textBox1.Handle);
    }

This seems a little hackish, though. There must be a better way.

Please try the below code 

[DllImport("user32.dll")]
static extern bool CreateCaret(IntPtr hWnd, IntPtr hBitmap, int nWidth, int nHeight);
[DllImport("user32.dll")]
static extern bool ShowCaret(IntPtr hWnd);

public Form1()
{
    InitializeComponent();
}

private void Form1_Shown(object sender, EventArgs e)
{
    CreateCaret(textBox1.Handle, IntPtr.Zero, 10, textBox1.Height);
    ShowCaret(textBox1.Handle);
}
