Exception filters give developers the ability to add a condition (in the form of a boolean expression) to a catch block, allowing the catch to execute only if the condition evaluates to true.
Exception filters allow the propagation of debug information in the original exception, where as using an...
Deprecated usage
The ConfigurationSettings class was the original way to retrieve settings for an assembly in .NET 1.0 and 1.1. It has been superseded by the ConfigurationManager class and the WebConfigurationManager class.
If you have two keys with the same name in the appSettings section of the ...
The ConfigurationManager class supports the AppSettings property, which allows you to continue reading settings from the appSettings section of a configuration file the same way as .NET 1.x supported.

Add an application setting named ExampleTimeout, using the time System.Timespan, and set the value to 1 minute:

When passing formal arguments to a generic method, relevant generic type arguments can usually be inferred implicitly. If all generic type can be inferred, then specifying them in the syntax is optional.
Consider the following generic method. It has one formal parameter and one generic type paramet...
Developers can be caught out by the fact that type inference doesn't work for constructors:
class Tuple<T1,T2>
{
public Tuple(T1 value1, T2 value2)
{
}
}
var x = new Tuple(2, "two"); // This WON'T work...
var y = new Tuple<int, string>(2, "t...
Custom filters can be set and save from the UI. In the AndroidMonitor tab, click on the right dropdown (must contains Show only selected application or No filters) and select Edit filter configuration.

It is possible to generate a Stream that does not end. Calling a terminal method on an infinite Stream causes the Stream to enter an infinite loop. The limit method of a Stream can be used to limit the number of terms of the Stream that Java processes.
This example generates a Stream of all natural...
Classes implementing Iterable<> interface can be used in for loops. This is actually only syntactic sugar for getting an iterator from the object and using it to get all elements sequentially; it makes code clearer, faster to write end less error-prone.

Annotation @XmlAccessorType determines whether fields/properties will be automatically serialized to XML. Note, that field and method annotations @XmlElement, @XmlAttribute or @XmlTransient take precedence over the default settings.

For every infix operator, e.g. + there is a operator-function (operator.add for +):
1 + 1
# Output: 2
from operator import add
add(1, 1)
# Output: 2
even though the main documentation states that for the arithmetic operators only numerical input is allowed it is possible:
from operator impo...
