The following is a list of C# Exceptions Handling Guidelines taken from Essential C# by Mark Michaelis.
Exception handling provides much-needed structure to the error-handling mechanisms that preceded it. However, it can still lead to some unwieldy results if used haphazardly. The following guidelines offer some best practices for exception handling.

The CIL of C# 6.0’s String Interpolation

,
January 2, 2015 / 2 Comments

One of the C# 6.0 features that will most simply and perhaps most predominantly affect the way you write C# code in the future is string interpolation.  Besides explaining composite string formatting (the old way – string.Format("{0} {1}", firstName, lastName) ) or obviously being relegated to a pre-C# 6.0 world, there is little reason to revert back from the string interpolation syntax.  Those of […]

While writing another MSDN magazine article on C# 6.0 (the third because the language continues to improve) I was looking for a good example of when to use the new “using static” feature.  Towards this effort, I used PowerShell to crawl through all the MSCORELIB types and output the ones meeting the following criteria:

Static Using Statement in C# 6.0

Another C# 6.0 “syntactic sugar” feature is the introduction of using static.  With this feature, it’s possible to eliminate an explicit reference to the type when invoking a static method.  Furthermore, using static lets you introduce only the extension methods on a specific class, rather than all extension methods within a namespace.  The code of Listing 1 below provides a “Hello […]
