With this post Bryant Likes aims to answer a question that came up in the Silverlight Forums about how to timeout a user when using .NET RIA Services.
Since I have implemented this before I thought I would share an approach I used. There might be a better way that is more integrated with the ASP.Net security, but for now this works.
To start with, you’ll need the Sample Application that Brad Abram has been building and blogging about and you might want to read through this post on Authentication in RIA Services before going any further. Once you have that and can build/run it on your machine you can continue on.
