Sometime back, I had written a similar article Load and Play a Video File at Runtime using Silverlight 2 Beta 2. The article made use of the OpenFileDialog class in Silverlight Beta2 to load files at runtime. There have been quite a few breaking changes from Beta 2 to the final release of Silverlight. One of these changes affects Silverlight 2 application using the OpenFileDialog. In this short article, we will study these changes and explore how to load and play media files at runtime using the OpenFileDialog control using the final release of Silverlight 2.
