Compile-Time Validation of Composite Object Data Binding Expressions

[Daniel Vaughan]

For those of you that might be interested, I have just published a
short article on my blog entitled Compile-Time Validation of Composite
Object Data Binding Expressions with Generated Metadata.
It shows how T4 generated metadata can be used to not only provide
compile time XAML validation of properties on classes, but also
composite classes, and anywhere you need to combine paths. Such as the
SelectedItem in a ListBox like so:
<Label Content="{Binding ElementName=listBox,
Path={Demo:JoinPath
SelectedItem,
{x:Static Metadata:PersonMetadata.Address},
{x:Static Metadata:AddressMetadata.StreetLine}}}"/>

Thanks Glenn! Once I get the next Calcium article out there, I want to
look into doing some validation with MSBuild and VS2010
d:DesignInstance, just as we were chatting about with Karl.
