Working with client side controls requires a lot of javascript, and I have often just written the javascript in the Render or RenderHTML functions of my web controls.  This works, but is NOT the best, or even a recommended method to do this.  So I began looking around and found this nice capability, but there are some major pitfalls to be aware of!

 This example is based on a current Mirolink development project for Virtual Earth 6.  The projects namespace is MicroLink.Applications.VirtualEarth.Core.  The javascript file is at the root level of the project and is Core.js.  This information is critical to be aware of in the steps below!

 ASP.NET 2.0 introducted the WebResource capability to include javascript, image, and other "resource" files within a DLL.  Using the WebResource is actually pretty simple, just follow these three steps.

Step 1

Add your resource (.js, .css, etc) to the project you want to bundle it with.  Set the Build Action property to Embedded Resource.

Step 2

In the AssemblyInfo.cs file, usually located in the Properties folder add the following line:

[assembly: WebResource("MicroLink.Applications.VirtualEarth.Core.Core.js", "application/x-javascript")]

***NOTE***
Notice that the resource name is actually formed [Package] {.[SubFolder}.[Filename].  This is not noted anywhere in the MSDN!

Step 3
In the class file add the following line for security

[AspNetHostingPermission(SecurityAction.Demand, Level= AspNetHostingPermissionLevel.Minimal)]

Finally to reference the resource:

string coreJS = this.Page.ClientScript.GetWebResourceUrl(this.GetType(), "MicroLink.Applications.VirtualEarth.Core.Core.js");
