Easier way to debug a Windows service
...ommand line switch for that purpose?
Couldn't you just do:
public static int Main(string[] args)
{
if (!Environment.UserInteractive)
{
// Startup as service.
}
else
{
// Startup as application
}

Difference between Lookup() and Dictionary(Of list())
...t least, I believe the concrete Lookup class is immutable, and the ILookup interface doesn't provide any mutating members. There could be other mutable implementations, of course.)
When you lookup a key which isn't present in a lookup, you get an empty sequence back instead of a KeyNotFoundException...

Cancellation token in Task constructor: why?

Passing a CancellationToken into the Task constructor associates it with the task.
Quoting Stephen Toub's answer from MSDN:
This has two primary benefits:

how to provide a swap function for my class?
...efine classes such as:
vec3<float> a;
vec3<double> b;
vec3<int> c;
if you want to be able to create one function to implement all 3 swaps (not that this example class warrants it) you do just like Xeo said in (2)... without specialization but just make a regular template functio...
Why are functions in Ocaml/F# not recursive by default?
...itly. Java, C# and Perl certainly do have implicit recursion. We could get into an endless debate about the meaning of "most" and the importance of each language, so let's just settle for "very many" other languages.

Confused about stdin, stdout and stderr?
...my understanding is correct, stdin is the file in which a program writes into its requests to run a task in the process, stdout is the file into which the kernel writes its output and the process requesting it accesses the information from, and stderr is the file into which all the exceptions ...
