However, by no means are you limited to these simple patterns.You’ll notice that all the methods discussed above are implemented as Funcs rather than actual methods.This transformation effectively assumes you have a folder (namespace) for the different views by removing the word “View” from the end and appending the context instead. One of the functions of Locate For Model is to inspect your View Model to see if it implements IView Aware.If so, it will call it’s Get View method to see if you have a cached view or if you are handling View creation explicitly.To do this, CM uses a simple naming pattern to find a User Control1 that it should bind to the View Model and display. To derive the view, we make an assumption that you are using the text “View Model” in the naming of your VMs, so we just change that to “View” everywhere that we find it by removing the word “Model”. If we don’t find the type, we generate a view with an appropriate “not found” message. This is how CM supports multiple Views over the same View Model. This means that for Views created by the View Locator, you don’t have to have code-behinds at all.This has the effect of changing both type names and namespaces. If a context (typically a string or an enum) is provided, we do a further transformation of the name, based on that value. You can delete them if that makes you happy :) You should also know that View Locator. It is always called indirectly through View Locator. Locate For Model takes an instance of your View Model and returns an instance of your View.This means that you can customize them by simply replacing them with your own implementations.

If you are going to use conventions, and since they are ON by default, it’s good to know what those conventions are and how they work. The first convention you are likely to encounter when using CM is related to view resolution. Once we have the name, we then search for types with that name.See the section below on property binding conventions. Micro prefers View Model-First development, there are times when you may want to take a View-First approach, especially when working with WP7.In the case where you start with a view, you will likely then need to resolve a View Model. While with View location we change instances of “View Model” to “View”, with View Model location we change “View” to “View Model.” The other interesting difference is in how we get the instance of the View Model itself.Rx UI bindings does not work that way; you have to provide a Data Template for them to work: No it's a legitimate bug with the View Model View Host and the Combobox in WPF land Essentially if a Item Template is set and it's a Content Control (which View Model View Host is) it'll call into https://referencesource.microsoft.com/#Presentation Framework/src/Framework/System/Windows/Controls/Combo Box.cs,871 It will then grab the Item from the control, set the Item Template for a new hosted control, and then set the View Model to be the previous View set on the control.
