How to get the SOS.DLL for silverlight 4.0.60310.0 for windbg

If you want to do the Silverlight debugging using windbg, the first thing is you have to get the sos extension for Silverlight.
When I try to run the command ‘.loadby sos coreclr’

get the error , it can’t find the sos.dll, in the silverlight folder,


I try to google “how to get the sos.dll for silverglight4.’, nothing is helpful, then I spend a little time to figure out how to get the sos.dll. So here is the answer,

1. Install visual studio 2010, if you are a developer, you probably have already installed the IDE
2. this is important, Download and install the Microsoft Silverlight 4.0 SDK

that’s IT.


#1 is very important, if you skip it and install the SDK only, it wont install the sos.dll for you.

IronRuby Tutorial, Ruby For C# programmers,Part 1

IronRuby is one of the DLR extension on Microsoft .net platform that enable you programming against .net using the Dynamic Language. I will put a very short tutorial, here.

  Download the assemblies or just the installer file from http://ironruby.codeplex.com/releases/view/49097#DownloadId=159561
for the installation, it basically puts several .net assemblies to the GAC folder. 

Then you can run the IronRuby console, which is the C# version of Irb


when you run process explorer, you will see the loaded Assemblies,

Ir.exe is a standard .net application,

Now, let’s write a basic HelloWorld Ruby application,
First in Ruby Style,


then In C#, we just call System.Console.WriteLine(“Message”). namespace will be mapped to module in Ruby,


Now, you can call the standard .net library, like Datetime


In Ruby, if you want to query the methods of the Object, you can use .methods, we can do this too.


if we want to change the Console foreground color, which we cant do in ruby easily,just call system.foreground_color
here, we can use ruby style naming like foreground_color, or C# style ForegroundColor, the dynamic method dispatcher will delver the call to the right stub,


To using the Base64 encoding that I used pretty often,


in Ruby, it’s easy to subclass to add more methods, say thing error here, I will add one method called writeerror

Seconds since the Unix epoch in C#/java, the same output of Time() in PHP

in Php, there is one Time() function, Returns the current time measured in the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT).
  in C#, there is no built-in function to return seconds since UNix epoch, here is the code snippet to return the same thing

int t = (int)DateTime.Now.ToUniversalTime().Subtract(new DateTime(1970, 1, 1, 0, 0, 0)).TotalSeconds;

In Java, there is one standard function, System.currentTimeMillis(),which measured in milliseconds, between the current time and midnight, January 1, 1970 UTC.


System.currentTimeMillis()/1000

Adobe Content Server, Error getting license License server communication problem: E_LIC_WRONG_OPERATOR_KEY

When I try to finish the fulfillment of one ebook using the digital edition, It returns this error.

However, when I test the http://server:8080/fulfillment/statuscheck, all passed.

wrong operater key always means that the p12 file we setup in the c:\config\fulfillment-conf.txt is incorrect.  it doesn’t match the url that do the fulfillment.

So there could be stupid typo mistake, check the fulfillment-conf make sure the com.adobe.adept.serviceURL is matching the cert url.
if you want to check the cert url, just click and import it to the certification store and open the certificate mmc

also it looks like the statuscheck never check the url match the operator certificate which we think it will do.
