Answer 1

Just follow the instruction to send the shortcut key to another application

Add this namespace to the class

using System.Runtime.InteropServices;

Then declare SetForegroundWindow function with DllImport statement. this will create object of that method which has been created in User32.dll

[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

And add the following code to your button click or anywhere in your project. This code will navigate the OpenFileDialog to open the existing file in Paint.NET application.

private void button1_Click(object sender, EventArgs e)
{
    Process p = Process.GetProcessesByName("PaintDotNet").FirstOrDefault();
    if (p != null)
    {
        SetForegroundWindow(p.MainWindowHandle); //Set the Paint.NET application at front
        SendKeys.SendWait("^(o)"); //^(o) will sends the Ctrl+O key to the application. 
    }
}

most of programmers made the mistake between Ctrl+O and Ctrl+o seems similar but, the ascii value of both key is different. So, make sure the key character is not in uppercase. You can also read the full information about SendKey method on msdn. You can make any key combination and send through the SendWait() method.

Just add one or some or all of the libraries to your project. as Measuring states then use the object explorer.

NOTE: never mind the .xaml stuff or the actual projects I am trying to render SharpDX D3D11 in a wpf app to make a map editor (and without the toolkit (don't ask me why. I am crazy)).

I swear I have the code last night are you trying to automate paint.net? you will have to make a plug-in which would make the process way more streamlined than having to start a second app.
