Wpf custom control binding not updating Chatweb adult com
Typically we would have one View per View Model, but that’s not a requirement at all (more like a generalized observation), and in fact there are some situations where we might want to have multiple Views for the same View Model (or break a complex View Model into multiple parts while still connecting to a single View).

Instead, this is meant to be a slightly more practical guide to squeezing performance out of WPF in ways that are probably more likely affecting you.

Two way binding is used when we want to update some controls property when some other related controls property change and when source property change the actual control also updates its property.
I think this sentence is hard to understand :) Let me explain you with an example.Blend-style behaviors also have their own set of lifetime problems.
