Debug With Mixed vs Debug with Native Only when debugging dump files

When I open a dump file, in VS2012, I see two options for debugging: Debug with Mixed and Debug with Native Only. I am wondering what these two options mean, and what the differences are between them.

I tried searching Google for documentation/etc. but could not find anything on these two options, and the closest that I came was finding a few posts where people said they used Debug with Mixed but didn't say why, and one post that noted that Debug with Native Only displays only for .NET 4.0.

Whether you choose Debug with Native Only or Debug with Mixed or Debug Managed Memory, depends on what your dump file is of.

1. Debug with Native Only: For native apps (it will allow you to see the callstack and source code from the native part of the app),

2. Debug with Mixed: Allows you to see the managed source code part as well.

3. Debug Managed Memory: Useful for debugging memory problems in managed code
