I don't understand where to use below methods while composing parts in MEF:
1. GetExports<> or GetExportedValue<> - Do I need to have Import while using GetExportValue<> method. - I tried out this and its working without Import then why one should need Import properties.
2. ComposeParts() - As I understand, this is satisfying all defined Imports to Exports.. but more clarification would be helpful.
3. ComposeExportedValues() - what is this? and in which scenario I should go for this.
In case of designing application which is already using PRISM (Composite WPF) framework , which of the above exporting functionality I should use.
