What is the difference between “INNER JOIN” and “OUTER JOIN”?
... tables, with the result being a new, temporary table. Joins are performed based on something called a predicate, which specifies the condition to use in order to perform a join. The difference between an inner join and an outer join is that an inner join will return only the rows that actually mat...

What are the benefits to marking a field as `readonly` in C#?
...is a potential case where the compiler can make a performance optimization based on the presence of the readonly keyword.
This only applies if the read-only field is also marked as static. In that case, the JIT compiler can assume that this static field will never change. The JIT compiler can take t...
Why implement interface explicitly?
...nstraint on T. While an object can generally only be safely cloned if its base can be, one may wish to derive from a base class which could be safely cloned an object of a class that can't. To allow for that, I'd recommend against having inheritable classes expose a public clone method. Instead h...
