C# is a strange language

[PaulM1985]

For example

bool check = true;

for(int i =0;i < 2;i++)
{
         check = !check;
         if(check)
         {
                 Console.WriteLine("Hello World");
         }
}

this will print "Hello World" twice (but only sometimes).

This claim was amazing. So amazing I downloaded Monodevelop to try it myself!

Here is my code:

using System;

namespace Test
{
	class MainClass
	{
		public static void Main (string[] args)
		{
			int wrong = 0;
			for (int j = 0; j < 500000; j++)
			{
				bool check = true;

				int testVal = 0;
				for(int i =0;i < 2;i++)
				{
					check = !check;
					if(check)
					{
						testVal++;
					}
				}
				
				if (testVal == 2)
				{
					wrong++;
				}	
			}
			
			Console.WriteLine("There were " + wrong + " wrong");
		}
	}
}

This prints:

There were 0 wrong

Which is exactly what I would expect. I can't make it do the weird stuff you mentioned.

I don't know how true that statement was, but a language that does random things like that is not reliable.

[PaulM1985]

True. I guess in addition you have to consider is the bytecode being compiled incorrectly or is the runtime interpretting it wrongly. Either way, it works fine on my Pc.

It only does it in visual studio , I think its the Visual Studio compiler because its even happened to me in C++ one time. Microsoft...

Using Microsoft Visual Studio 2010 and .NET 4.0 on Windows 7, I still can't reproduce the issue you are talking about.

I think C# is a good language. I have found it to be quite reliable and easy to use, especially moving to it from a Java background. It's ability to use C and C++ code also makes it great for building on top of old systems with "tried and tested" libraries without having to re-write stuff for a new programming language/technology.

Rather than start a new thread I thought this might be a good place to ask this opinion question: Though C# is an OS agnostic language due to the Mono project, is there any concern of "vendor lock-in" with the language? Especially concerning it's relation to the .Net framework which was designed to be Windows-only? Does the legal shadow over the project worry anyone? I've always avoided C# for this reason but I wonder if it's FUD spread by the FOSS community or are the worries well founded?

[PaulM1985]

I think that possibly there may be some issue. As the language (or rather Windows implementation) grows it may be that open source projects can't keep up with the rate of growth. This has already happened in the Mono project in that they have said that they will not be providing support for Windows Presentation Framework (WPF) which is a new way of developing user interfaces in .NET.

I have heard that Microsoft actually helped out a lot with mono ,so I'm not worried.

I don't think so although the stigma exists in addition the development of the language and hence its standardization is done almost entirely by Microsoft, who only supports it's own operating system.. (I am still surprised that Office for Mac exists).

Especially concerning it's relation to the .Net framework which was designed to be Windows-only?

That got nothing to do with the programming language per-se just as it was designed for it.

Does the legal shadow over the project worry anyone?

Not sure what legal shadow you are referring to?

I've always avoided C# for this reason but I wonder if it's FUD spread by the FOSS community or are the worries well founded?

The reason is mostly stigma but in addition as far as I can tell C# standard is only 5 years and non-Microsoft specific C# libraries and toolkits are few so why switch to use C# on Linux/Solaris/MacOS etc, when you can use C/C++ or Objective-C on a Mac, which have 20-30 years under their belts and quite a bit of tools already written?

The only way I could see mass acceptance of C# as a development platform on Linux for example is that there is a significant push from a major commercial player that does its own software development to dump Microsoft as a desktop platform of choice and even then I see better chance of using Java then C#.

With what exactly?
