How do I get my C# program to sleep for 50 msec?
...eature, the best way to sleep for 50ms is by using Task.Delay:
async void foo()

async void foo()
{
// something
await TaskEx.Delay(50);
}

:let &tw=40
But, for example, assigning 50 to the global variable foo (:let g:foo=50) cannot be achieved with a :set command (because g:foo is a variable and not an option).
Some options are boolean like. When setting these, no value is needed (as in :set noic and the opposite :set ic).

Why does this assert throw a format exception when comparing structures?
...d that's what's failing. Ouch.
Indeed, we can prove this really easily by fooling the formatting to use our parameters for the expected and actual parts:
var x = "{0}";
var y = "{1}";
Assert.AreEqual<object>(x, y, "What a surprise!", "foo", "bar");
The result is:
Assert.AreEqual failed. E...

Try matching foobar against these:
/foo(?=b)(.*)/
/foo(?!b)(.*)/
The first regex will match and will return "bar" as first submatch — (?=b) matches the 'b', but does not consume it, leaving it for the following parentheses.

One-liner to recursively list directories in Ruby?
...) # for directories
Dir.glob("**/*") # for all files
