I've been using a pattern in an application where I'm setting arbitrary attributes on Expando class models in an App Engine app. This works as expected, but hasn't yet been tested with a really large data set. And over time, the number of attributes might get to be > 1000. It also makes the table in the administration console scroll fa...
I added a custom user field in Liferay, and set a value on a specific user. How can I access this value programmatically?

(see old post http://stackoverflow.com/questions/3010147/what-is-the-return-type-for-a-anonymous-linq-query-select-what-is-the-best-way-t) So in LINQ queries you form the type of return value you want within the linq query right?
