Internet Information Services 7 (IIS7) has a great new set of features regarding configuration. Using the Integrated Configuration system, you can configure your server from XML files, the IIS7 manager, the command prompt using the APPCMD tool, but IIS7 also lets you manage your server from managed code in a very intuitive manner.
If you navigate to the %WINDIR%\System32\InetSrv folder in Windows Vista, you'll find all the executables, DLL's and XML (.config) configuration files you need. It doesn't matter if you use the IIS7 Manager, managed code or the APPCMD command-line based tool to manage your server - at the end of the day you are changing an XML file. That is applicationHost.config which is located here: C:\Windows\System32\inetsrv\config\applicationHost.config.
The integrated configuration system on IIS7 is great news for hosters, and web developers. Hosters can easily automate server management through managed code, and as a web developer, you can configure your server from your web.config file, which makes it easy to move your web application from development, to test, and further up towards production. Read my post on how to set a websites default document, from within the web application's web.config file.
In this post, I will create an application pool on my local IIS7.
Launch Visual Studio 2005 or 2008 - whatever you've got will work.
Create a new Console Application, and give it a name of your own choice.
Right click References in the Solution Explorer and add a new reference.
Locate Microsoft.Web.Administration.dll from the C:\Windows\System32\inetsrv folder.
To access IIS7, we use the ServerManager class, as shown below.
1: using System;
2: using System.Collections.Generic;
3: using System.Linq;
4: using System.Text;
5: using Microsoft.Web.Administration;
6:
7: namespace Iis7ManagementTest
8: { 9: class Program
10: { 11: static void Main(string[] args)
12: { 13: ServerManager mgr = new ServerManager();
14:
15: // Add a new application pool called MyAppPool
16: ApplicationPool myAppPool = mgr.ApplicationPools.Add("MyAppPool"); 17:
18: // Configure my new app pool to start automatically.
19: myAppPool.AutoStart = true;
20:
21: // What action should IIS take when my app pool exceeds
22: // the CPU limit specified by the Limit property
23: myAppPool.Cpu.Action = ProcessorAction.KillW3wp;
24:
25: // Use the Integrated Pipeline mode
26: myAppPool.ManagedPipelineMode = ManagedPipelineMode.Integrated;
27:
28: // Set the runtime version of ASP.NET to 2.0
29: myAppPool.ManagedRuntimeVersion = "V2.0";
30:
31: // Use the Network Service account
32: myAppPool.ProcessModel.IdentityType = ProcessModelIdentityType.NetworkService;
33:
34: // Shut down after being idle for 5 minutes.
35: myAppPool.ProcessModel.IdleTimeout = TimeSpan.FromMinutes(5);
36:
37: // Max. number of IIS worker processes (W3WP.EXE)
38: myAppPool.ProcessModel.MaxProcesses = 1;
39:
40: // Commit the changes
41: mgr.CommitChanges();
42: }
43: }
44: }
After the application has been executed, we will see our new application pool inside the IIS7 Manager:
That's all for now. In another blog post I will show how to add a new web site, that will use our new application pool - also from managed code.
