Visual Studio (2008) crash when trying to add pipeline components to toolbox

I have been working on a pipeline components library. I encountered a strange issue when I tried to add a new pipeline component which I have added to the library. Every time I tried to "Choose Items..." in the pipeline components toolbox and choosed BizTalk Pipeline Components tab, my visual studio 2008 crashed. I don't remember whether I have encountered the same problem when I used visual studio 2005.

Thanks to Thiago Almeida, I found the solution: add the pipeline components into the Toolbox when the entire solution closed.

The Changes to the referenced assembly are not automatically picked up in BizTalk Project

One of my colleagues encountered this issue when he used Visual Studio 2008.

If your BizTalk project references another assembly, and that assembly is updated, the updates or changes are not automatically picked up in your BizTalk project.

There are some alternatives to update the referenced assembly:

1. You should remove the outdated reference in Solution Explorer, and then add the reference back (re-reference the assembly).
2. Or, you can close your solution and reopen it. In either case, the latest updates to the referenced assembly are available to your project.
3. Alternatively (as Samad Khan suggested): Select the updated assembly under references, Press F4 to bring up the properties windows, Set the “Copy Local” design time property from “True” to “False”, and Change back the design time property “Copy Local” from “False” to “True”.
