C# Blooper №9: Annoying case statement fall-through rules

Before reading any further, please read the disclaimer in the C# Bloopers post.

Overall, C# takes an approach which is far more friendly to novice programmers than its predecessors, C and C++ were. For example, in the case of switch statements, C# does not allow the old, error-prone style of C and C++ where you could simply fall through from one case statement to the following one; instead, at the end of each case statement C# requires either a break statement, or a goto statement to explicitly jump to another label. That's all very nice and dandy, except for one thing: C# requires a break or goto even at the last case statement of a switch statement!

C# Blooper №10: Switch statements are not properly formatted

Before reading any further, please read the disclaimer in the C# Bloopers post.

This is rather a Microsoft Visual Studio blooper than a Microsoft C# blooper: When formatting source code, Visual Studio offers an "indent case contents" option, but you will only find it useful if you happen to have a crooked notion as to how switch statements should be formatted. The one and only normal form of formatting switch statements is not supported.

C# Blooper №8: No warnings for conditions that are always true/false

Before reading any further, please read the disclaimer in the C# Bloopers post.

The Microsoft C# compiler does not issue 'condition is always true' and 'condition is always false' warnings. Perhaps these warnings are not particularly meaningful in Java, which lacks conditional compilation directives, and therefore if( true ) and if( false ) are the only means of achieving conditional compilation; but in C#, which has special conditional compilation directives, conditions which are always true or always false are invariably so by mistake; therefore, these warnings would indeed be meaningful, and useful.

Why the Microsoft C# compiler lacks many useful warnings

As my C# Bloopers series of articles shows, the Microsoft C# compiler fails to issue many useful warnings which one would reasonably expect from a decent compiler of any language, and which are in fact readily and lavishly issued by Java compilers.

After all these years that the Microsoft C# compiler has been maturing, one cannot help but postulate that there are ulterior motives behind this continued state of misery with respect to warnings. For lo and behold, it just so happens that the "Ultimate" (most feature-packed and most outrageously expensive) edition of Microsoft Visual Studio contains a "Code Analysis" feature, which is capable of issuing hundreds of different types of warnings, ranging from the pedantic to the arcane, and including most, if not all, of the missing warnings that I am discussing here.

C# Blooper №7: No warnings about unused private methods

Before reading any further, please read the disclaimer in the C# Bloopers post.

If you have a private method which is never used, you will not be given a warning about it by the Microsoft C# compiler. This means that your app will likely get shipped with unnecessary chunks of code in it, some of them possibly containing string literals that were never meant to make it out of the development environment, or even requiring libraries to be linked which were never meant to be required on the field.

How to get a raise

Once upon a time I was dissatisfied with my salary at my workplace, and I let it show. The boss, fearing that he was about to lose me, placed an ad in the newspaper for my exact job description. Since I was looking for a job, I saw the ad in the newspaper. What I did was to reply to that ad, sending my boss my resume, which of course included precisely those qualifications that the job required. The boss got the message.
