Contrary to what many believe, C# is NOT proprietary...Java is actually proprietary. However, because Microsoft still dominates its direction, it may be considered to be "semi-de facto" proprietary at this stage.
C# traded off some runtime speed for safety and quick development. More optimized compilers in the near future may reduce this speed disadvantage while retaining the advantages.
Holistically, C# is perhaps the best programming language in existence.
C# is much like C++ in syntax, but it is simpler to write object oriented code with it as the .NET Framework provides built in code libraries you can use across all the Framework languages, like TextWriter to write a text file. No need to manually write mountains of code to write a text file like some languages.
It has a Garbage Collector or GC, which differs it from C++ greatly. The GC cleans up memory so you don't have to manage it, nice eh? Stops most memory leaks (you online gamers know of them, as almost every game is written in C++ and those CTDs are usually memory leaks) so as long as you ain't a code tool you should be safe with the GC releasing the objects from memory.
There is also the GAC, or Global Assembly Cache. It is the residence of the .NET Framework and anything you want to add like a custom library or assembly, basically a collection of commonly used code, making it accessible to any .NET application on that machine or web server if running ASP.NET.
I can code faster than the those "other devs" with C# as it has more available built in libraries. Suck that Java devs. Yeah Java can import your crap libraries you can barely trust in most instances, but I already got my library in the GAC and it's pretty trust worthy if not a huge compilation of somewhat brilliant and reusable code.
But c'est la vie. Hey I know French as well as C# motherfuckers. So bring it and I'll code a single method to slump your asses till you have no more Friends to code against me!
And as Ctrl-Z wrote along these lines, the path of the righteous man is beset on all sides by the iniquities of the selfish and the tyranny of evil men. Blessed is he, who in the name of C# and good will, shepherds the weaker entry level .NET devs through the valley of darkness and J2EE, for he is truly his brother's keeper and the finder of lost coders. And I will strike down upon thee with great vengeance and furious anger those Java coders who would attempt to poison and destroy my brother C# coders. And you will know my name is the Mikro$oft when I lay my vengeance upon thee Java! HAHA isn't Sun laying off, Have the Gates already begun to strike?
Some clever dick wanted a name like (C++)++ and noticed that there were 4 +s hidden in a '#' character. So C#.
Trouble is, Brits and Americans say the thing differently so they decided you must forget 'hash', 'pound', 'number' and say 'C-sharp'
n. psudo language thats syntax is simular to actual programming languages.
n. Lanugage designed by Microsoft as an answer to Java. Primary problem was that Microsoft forgot the question. Used to avoid paying licensing fees to a competitor, Sun.
