.NET Zero Deployment 요약

>> 원문 : http://msdn.microsoft.com/msdnmag/issues/02/07/NetSmartClients/default.asp 


1. Application Download
- virtual directory

2. Versioning

// Strong naming is required when versioning
[assembly: AssemblyKeyFileAttribute("wahoo.key")]
[assembly: AssemblyVersionAttribute("1.2.3.4")]

3. Related Files

- GAC
- download cache

string appbase = AppDomain.CurrentDomain.BaseDirectory;

private void InitializeComponent() {
 System.Resources.ResourceManager resources =
   new System.Resources.ResourceManager(typeof(MainForm));
 ...
 this.game.BackgroundImage = ((System.Drawing.Bitmap)
   (resources.GetObject("game.BackgroundImage")));
 ...
}

public MainForm() {
 // Let the Designer-generated code run
 InitializeComponent();

 // Init culture-neutral properties
 this.game.BackgroundImage = new Bitmap(typeof(MainForm),
   "sblogo.gif"); // WARNING: Case sensitive
}

[assembly: NeutralResourcesLanguageAttribute("en-US")]

.config 파일이 캐시된 후에는 신버전이 있더라도 다시 다운로드하지 않는다!


4. Security Zones

using System.Security;
using System.Security.Policy;

SecurityZone zone = Zone.CreateFromUrl(appbase).SecurityZone;


5. Isolated Storage

- 생성/조회

private IsolatedStorageFileStream CreateSettingsStream() {
 IsolatedStorageFile store =
   IsolatedStorageFile.GetUserStoreForDomain();

 return new IsolatedStorageFileStream("settings.txt",
   FileMode.Create, store);
}

private IsolatedStorageFileStream OpenSettingsStream() {
 IsolatedStorageFile store =
   IsolatedStorageFile.GetUserStoreForDomain();

 return new IsolatedStorageFileStream("settings.txt",
   FileMode.Open, store);
}

- 저장

private void LoadSettings() {
 try {
   using( Stream       stream = OpenSettingsStream() )
   using( StreamReader reader = new StreamReader(stream) ) {
     Location = (Point)ReadSetting(reader, typeof(Point));
     ClientSize = (Size)ReadSetting(reader, typeof(Size));
   }
 }
 catch {
   // If there's nothing to read,
   // put the form in the center of the screen
   StartPosition = FormStartPosition.CenterScreen;
 }
}

private void SaveSettings() {
 // Restore so we don't store a zero size or location
 WindowState = FormWindowState.Normal;

 // Save the window location
 using( Stream       stream = CreateSettingsStream() )
 using( StreamWriter writer = new StreamWriter(stream) ) {
   WriteSetting(writer, Location);
   WriteSetting(writer, ClientSize);
 }
}

- Type Conversions functions

private object ReadSetting(StreamReader reader, Type type) {
 TypeConverter   converter = TypeDescriptor.GetConverter(type);
 return converter.ConvertFromString(reader.ReadLine());
}

private void WriteSetting(StreamWriter writer, object obj) {
 Type            type = obj.GetType();
 TypeConverter   converter = TypeDescriptor.GetConverter(type);
 writer.WriteLine(converter.ConvertToString(obj));
}


6. Web Service와 통신

WahooScoresService GetService() {
 WahooScoresService  service = new WahooScoresService();

 try {
   string appbase = AppDomain.CurrentDomain.BaseDirectory;

   // Set URL to server where this came from
   string site =
     System.Security.Policy.Site.CreateFromUrl(appbase).Name;
   service.Url = service.Url.Replace("//localhost/",
     "//" + site + "/");
 }
 catch( ArgumentException ) { }
 return service;
}

void GetHighScores() {
 // Get scores
 WahooScoresService service = GetService();
 WahooScore[] scores = service.GetScores();

 // Show high scores...
}


7. Reading and Writing Files

SaveFileDialog dlg = new SaveFileDialog();
dlg.DefaultExt = ".txt";
dlg.Filter = "Text Files (*.txt)|*.txt|All files (*.*)|*.*";

// NOTE: Not allowed unless we have FileIOPermission
//dlg.AddExtension = true;
//dlg.FileName = "somefile.txt";

if( dlg.ShowDialog() == DialogResult.OK ) {
 // NOTE: Not allowed to call dlg.FileName
 using( Stream stream = dlg.OpenFile() )
 using( StreamWriter writer = new StreamWriter(stream) ) {
   writer.Write("...");
 }
}

- Check Permission 

// Check permission helper
bool HavePermission(IPermission perm) {
   try { perm.Demand(); }
   catch( SecurityException ) { return false; }
   return true;
}

void SaveHighScore(string name, int score) {
 IPermission perm =
   new FileDialogPermission(FileDialogPermissionAccess.Save);

 if( !HavePermission(perm) ) {
   MessageBox.Show("Doh!");
   return;
 }
 ...
}


8. 접근권한

- 제한된 어셈블리로부터 호출될 수 있는 권한

[assembly: AllowPartiallyTrustedCallersAttribute]

9. IEExec 

Usage: ieexec.exe url flags [securityZone] [domainId]
url          Assembly to launch, e.g. http://localhost/foo.exe 
flags        Flags to control execution. Values that can be
            added together are:
            0:   no flags
            1:   create evidence for the zone
            2:   create evidence for the site
securityZone If evidenceFlags != 0, sets the security zone.
            Values can be {0, 1, 2, 3} for
            {MyComputer, Intranet, Trusted, Internet}
domainId     If evidenceFlags != 0, unused hex-encoded bytes.
            Use 00.
