Sandbox solutions for custom webparts?

In Sharepoint 2007 it was very difficult to properly deploy customization.  The correct way to do it was generate a Sharepoint Deployment Solution which involved a lot of work to properly create the installation manifest.

Also, custom web parts were essentially global.  You could restrict them to a specific web application but it was tricky.

Done incorrectly with bad code a farm could be put at risk.

Now, you can use Visual Studio 2010 to create customization that can be published to a specific location without affecting or endangering the entire farm.

can you send any examples about sandbox solutions.

No.  The best thing to do is setup a Sharepoint 2010 development environment and create one.

I attended a Sharepoint 2010 Deep Dive in Redmond, WA at the Microsoft headquarters.  Creating a web part using a sandbox solution is super easy.

The hard part is getting a development environment up and running.

Now i created the Development environment.can you send any one sandbox solution webpart examples.
