As ASP.NET vNext is not yet available and my app uses MVC5 I would have to migrate the MVC app completly to Nancy or something similar. MVC5 is too dependend on IIS.
To solve this meanwhile I decided on an intermediate solution as performance is not an issue:
My console app creates an IIS config file and launches an IIS express:
// start IIS
bool systray = Debugger.IsAttached;
ProcessStartInfo psi = new ProcessStartInfo(iisExecutable, String.Format("/config:"{0}" /site:Ecm2.Web /trace:info /systray:{1}", configFile, systray));
psi.UseShellExecute = false;
psi.RedirectStandardInput = false;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
psi.CreateNoWindow = true;
if (this.iisProcess != null) throw new NotSupportedException("Multiple starts not supported");
this.iisProcess = new Process();
this.iisProcess.StartInfo = psi;
this.iisProcess.ErrorDataReceived += OnErrorDataReceived;
this.iisProcess.OutputDataReceived += OnOutputDataReceived;
this.iisProcess.Start();
this.iisProcess.BeginErrorReadLine();
this.iisProcess.BeginOutputReadLine();
If someone would like, this is part of the "stop" fragment:
if (this.iisProcess == null) throw new Exception("Does not look like there was something started yet!");
if (this.iisProcess.HasExited)
{
log.WarnFormat("IIS has already exited with code '{0}'", this.iisProcess.ExitCode);
this.iisProcess.Close();
return;
}
log.InfoFormat("Stopping IIS instance #{0}", this.instanceId);
ProcessCommunication.SendStopMessageToProcess(this.iisProcess.Id);
bool exited = this.iisProcess.WaitForExit(30000);
if (!exited)
{
log.WarnFormat("Failed to stop IIS instance #{0} (PID {1}), killing it now", this.instanceId, this.iisProcess.Id);
this.iisProcess.Kill();
}
this.iisProcess.Close();
To stop the iis process ordinary you should send WM_QUIT to it. This might be helpful for this:
/// <summary>
/// Sends a WM_QUIT message to another process.
/// </summary>
/// <param name="pid">PID of the other process</param>
public static void SendStopMessageToProcess(int pid)
{
log.DebugFormat("Sending stop message to PID #{0}", pid);
try
{
for (IntPtr ptr = NativeMethods.GetTopWindow(IntPtr.Zero); ptr != IntPtr.Zero; ptr = NativeMethods.GetWindow(ptr, 2))
{
uint num;
NativeMethods.GetWindowThreadProcessId(ptr, out num);
if (pid == num)
{
HandleRef hWnd = new HandleRef(null, ptr);
NativeMethods.PostMessage(hWnd, 0x12, IntPtr.Zero, IntPtr.Zero);
return;
}
}
}
catch (ArgumentException ex)
{
log.Error(String.Format("Failed to send WM_QUIT to PID #{0}", pid), ex);
}
}
/// <summary>

/// </summary>
