sqlite - What is a mixed mode assembly?

Question

I am looking at the System.Data.SQLite download page, and it lists mixed mode assembly for .NET 4 and a regular (I assume). My project that is going to use this library is all .NET 4 which will be compiled to x86.

I have 2 questions:

1. What is a mixed-mode assembly? Google returns a confusing array of answers, none of which make a lot of sense. One answer states that it's all about mixing native and managed code, while others claim its for mixing .Net versions.
2. Which download should I get for my situation?

Answer 1

1) Allways check msdn first. Mixed mode means that the assembly can run managed and unmanaged code.

2) Setups for 32-bit Windows (.NET Framework 4.0)

You kinda answered that question yourself "My project that is going to use this library is all .NET 4 which will be compiled to x86."
