    1. COEverything after "Any time a struct is cast to an interface, it is boxed" is somewhat out-of-topic . . . but in the same time, it made me realize something important about generics, structs and interface, something a straight complete answer wouldn't have, namely, the difference between `bar<T>(IComparable<T> value)` and `bar<T>(T value) where T : IComparable<T>`, and so, why interfaces still matter a lot for structs, as long as we uses generics correctly. +1.

    2. CO@paercebal: To my mind, what matters is not whether an answer precisely answers the exact question asked, but whether it provides information that will be useful to the original asker, and other people who click on the question. I figured that you would not only want to know whether a particular syntax would cause boxing, but also whether there would be an alternative way to write the code that would not. BTW, if I want to find out whether something will cause boxing, I write a simple program to create a WeakReference pointing to a new object (which is otherwise unused), then...

    3. CO...I run the operation that might or might not require boxing a million times, and then see if the WeakReference is still valid. If the operation required any sort of heap allocation, a garbage-collection will occur and the WeakReference would be voided. If not, it won't. Note that there may be even better ways to detect garbage collection, but this way is pretty quick and easy to test.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
