I have an asp.net mvc application that spawns a Process as follows:

        Process p = new Process();

        p.EnableRaisingEvents = true;
        p.Exited += new EventHandler(p_Exited);

        p.StartInfo.Arguments = "-interaction=nonstopmode " + inputpath;
        p.StartInfo.WorkingDirectory = dir;

        p.StartInfo.UseShellExecute = false;
        p.StartInfo.FileName = "pdflatex.exe";

        p.StartInfo.LoadUserProfile = true;

        p.Start();
        p.WaitForExit();

Before going further, I need to know whether, e.g., pdflatex.exe is a managed code or a native code?

Edit

I need to consider this because: (Hopely I am not wrong...)

1. Each Asp.net application runs in an separate/isolated AppDomain as opposed to a separate/isolated process.
2. A native executable cannot live in an AppDomain.

to be continued...

Shortly speaking, I hope my site does not spawn a new process for each request. Because a process is more expensive than an application domain.
