How to: Deploying Sliverlight applications in different machines

I am working on my silverlight application and i need to deploy the same on multiple machines as i need to test its performance on different servers.

Here is a small work around to do this.

  • Unzip the .XAP file in the clientBin folder of the website with WinRar or other archivator or Rename your XAP file to zip
  • Extract the zip file to a folder
  • Edit ServiceReference.ClientConfig in notepad
  • Here is the snippet of ServiceReference.ClientConfig.
<configuration>
    <system.serviceModel>
        <bindings>
            <customBinding>
                <binding name="CustomBinding_DPService" closeTimeout="00:10:00" openTimeout="00:10:00" sendTimeout="00:10:00"  receiveTimeout="00:10:00">
                    <binaryMessageEncoding />
                    <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647">
                        <extendedProtectionPolicy policyEnforcement="Never" />
                    </httpTransport>
                </binding>
            </customBinding>
        </bindings>
        <client>
            <endpoint address="/SLSampleWebsite/DPService.svc" 
                binding="customBinding" bindingConfiguration="CustomBinding_DPService"
                contract="ServiceReference1.DPService" name="CustomBinding_DPService" />
        </client>
    </system.serviceModel>
</configuration>



  • Update the endpoint address in the XML with relevant address if its hosted in different machine or in the same machine.


  • Add the folder contents to ZIP file



            <endpoint address="http://Server1/SLSampleWebsite/DPService.svc" 



  • After updating the ServiceReference.ClientConfig, Compress all files again to create new .ZIP file.


  • Delete the old .XAP file and remame the .ZIP to XAP file



It works great!

How To: Get File Time [C#]

To get file time information like attributes and all or when any file was created, last modified or accessed. For getting this you can get file DateTime info by using either static methods of File class or instance methods of FileInfo class.

Get file times using File class

Use File class when you want to get just one specific time, for example if you are only interested in a file last modification time. To do this use static method File.GetLastWri teTime with file path as a parameter. File class also provides static methods to get file creation time or file last access time. You can also get this times in UTC, e.g. to get file last write time in UTC use File.GetLastWri teTimeUtc.

// local times
DateTime creationTime = File.GetCreationTime(@"c:\Demo.txt");
DateTime lastWriteTime = File.GetLastWriteTime(@"c:\Demo.txt");
DateTime lastAccessTime = File.GetLastAccessTime(@"c:\Demo.txt");
// UTC times
DateTime creationTimeUtc = File.GetCreationTimeUtc(@"c:\Demo.txt");
DateTime lastWriteTimeUtc = File.GetLastWriteTimeUtc(@"c:\Demo.txt");
DateTime lastAccessTimeUtc = File.GetLastAccessTimeUtc(@"c:\Demo.txt");
// write file last modification time (local / UTC)
Console.WriteLine(lastWriteTime);     // 5/25/2010 10:10:00 PM
Console.WriteLine(lastWriteTimeUtc);  // 5/25/2010 10:10:00 PM


Get file times using FileInfo class



Use instance of  FileInfo class when you want to get more than one file time or any other information's about the file (like file attributes). Advantage is that you will get all needed information's just in one disk access. See following example.



FileInfo fileInfo = new FileInfo(@"c:\Demo.txt");
// local times
DateTime creationTime = fileInfo.CreationTime;
DateTime lastWriteTime = fileInfo.LastWriteTime;
DateTime lastAccessTime = fileInfo.LastAccessTime;
// UTC times
DateTime creationTimeUtc = fileInfo.CreationTimeUtc;
DateTime lastWriteTimeUtc = fileInfo.LastWriteTimeUtc;
DateTime lastAccessTimeUtc = fileInfo.LastAccessTimeUtc;
// write file last modification time (local / UTC)
Console.WriteLine(lastWriteTime);     // 5/25/2010 10:10:00 PM
Console.WriteLine(lastWriteTimeUtc);  // 5/25/2010 10:10:00 PM


Hope this is useful.

Disabling Browser Cache In C# and ASP.NET

Disable browser caching seems to revolve around how to make it work in IE, Mozilla and other browsers.

Here is the code that will disable browser cache. I have used this and it worked for me.

//Used for disabling page caching 
 HttpContext.Current.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
 HttpContext.Current.Response.Cache.SetValidUntilExpires(false);
 HttpContext.Current.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
// Requires for IE
 HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
// Requires for Mozilla
 HttpContext.Current.Response.Cache.SetNoStore();
