Do try/catch blocks hurt performance when exceptions are not thrown?
...ook behind to see what is generated for both the cases. Here is the code:
C#:
private static void TestWithoutTryCatch(){
Console.WriteLine("SIN(1) = {0} - No Try/Catch", Math.Sin(1));
}
MSIL:
.method private hidebysig static void TestWithoutTryCatch() cil managed

Deep cloning objects
...erenced source):
In case of you prefer to use the new extension methods of C# 3.0, change the method to have the following signature:
public static T Clone<T>(this T source)
{
//...
}
Now the method call simply becomes objectBeingCloned.Clone();.

Does the use of the “Async” suffix in a method name depend on whether the 'async' modifier is used?
...rd (Async in Visual Basic) is
considered an asynchronous method, and the C# and Visual Basic
compilers perform the necessary transformations to implement the
method asynchronously by using TAP. An asynchronous method should
return either a Task or a Task<TResult> object.

Is it considered acceptable to not call Dispose() on a TPL Task object?
...in this post: Typesafe fire-and-forget asynchronous delegate invocation in C#
It looks like a simple extension method will handle all trivial cases of interacting with the tasks and be able to call dispose on it.
public static void FireAndForget<T>(this Action<T> act,T arg1)

What is the proper declaration of main?
...e question is tagged both [c++] and [c++-faq]. I can't help it if Java or C# users (or anyone else) are still confused. C# requires Main to be a static member function because it doesn't even have nonmember functions. Even C89 requires main to return int. I am not sufficiently familiar with K&am...
In C#, why is String a reference type that behaves like a value type?
...
@Matt: exactly. When I switched over to C# this was kind of confusing, since I always used (an do still sometimes) .equals(..) for comparing strings while my teammates just used "==". I never understood why they didn't leave the "==" to compare the references, alth...
Is ServiceLocator an anti-pattern?
...ing the not very best solution.
Here is a paragraph from Adaptive Code Via C#:
"Unfortunately, the service locator is sometimes an unavoidable anti-pattern. In some application types— particularly Windows Workflow Foundation— the infrastructure does not lend itself to constructor injection. In ...
What is a Y-combinator? [closed]
...e.
Below is an example of how the usage and working of a Y-Combinator, in C#.
Using a Y-combinator involves an "unusual" way of constructing a recursive function. First you must write your function as a piece of code that calls a pre-existing function, rather than itself:
// Factorial, if func d...

Why Func instead of Predicate?
...I think Skeet's point is that Expression<> isn't a guideline. It's a C# compiler feature to recognise that type and do something different with it.
