Sometimes there comes a need to refer to a Silverlight assembly from several different projects, the last thing you want is to copy the assembly to every project, you want it in the GAC.

Silverlight environment is not .NET and simply adding the assembly to the GAC with gacutil gives no effect.  On the other hand one may notice the standard Silverlight assemblies in “Add reference” dialog of Visual Studio after having installed Silverlight.

As it turns out, to be able to refer to any assembly from any project with “Add reference” all that’s needed is a special key in the registry:

• openHKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MicrosoftSDKs\Silverlight\v4.0\AssemblyFoldersEx
• if you have a 32-bit Windows, remove the Wow6432Node part.
• Create a registry key with the name of your project
• Add the default value containing the path to the assemblies

Now “Add reference” will show all the assemblies from the path in the key.

The solution turned out to be quite straight-forward.  Hope this helps.

Creating a Cross-Browser Box-Shadow

Here’s a very simple way to implement the box-shadow in css. Perhaps the idea is too simple and obvious for the esteemed writers of the Internet to ever want to publish it.

First, the compliant browsers:

div {
background: green; /* required for IE */
-webkit-box-shadow: 0px 0px 15px #222;
-moz-box-shadow: 0px 0px 15px #222;
box-shadow: 0px 0px 15px #222;
}

The idea really boils down to applying the shadow filter four times with different directions. This way the shadow wraps around the edges of the container.
