Silverlight 4 Out of Browser

Silverlight 3 introduced an out of browser mode that provided a standalone experience for running Silverlight applications using the same execution sandbox model as when running in the browser. For the upcoming Silverlight 4, the out of browser support is being extended to allow an application to either run in a sandbox or as a trusted program. A variety of new resources are available covering these extensions.

Joe Stegman has a Channel 9 video covering Silverlight 4 out of browser mode improvements. As Joe mentions during the interview, he also gave a PDC talk on the subject. Out of browser execution was also a part of the overview that Karen Corby gave for Silverlight 4 at PDC. Finally, the Silverlight team has prepared a security whitepaper for Silverlight 4, including these new extensions.
