Last week I’ve blogged about using SQLite in an MVVM scenario in Windows Phone 8. Since, in my opinion, the post was already getting to an epic length I decided to leave out a part for this week. I’ll try to keep it a bit shorter this time, should be able to. The part I left out was using relationships and foreign keys with SQLite and the sqlite-net library. I’ll be building upon the project of the previous post, so the task schedule thingy. What we’ll be doing is adding the possibility of creating subtasks so that a task can be divided into smaller tasks. Note that this is just a proof of concept (POC) it’s in no way a complete application and it will have some strange things but that’s the whole fun of a POC.
