QUESTION
I need the ability to be able to store a Linq query as a string in the database and then load it and run it at a later date.
I am having extreme difficulty wrapping my head around how to do this.
I found this library that says it can do it: https://github.com/esskar/Serialize.Linq
But the blog that held the documentation is down and I can't figure it out from the examples, too much is going on.
Can anyone show me or link me to a simple example of a linq statement being serialized and then deserialized and run?

The IQueryable ToString() Method allows you to programmatically retrieve the SQL that the IQueryable object will generate and run as the database query.
Then you can use that SQL string in Entity Framework Raw SQL Queries.
the examples below will use the out of the box Microsoft ASP.NET Identity DbContext.
