The "In a Nutshell" books from O'Reilly are fantastic, as has been mentioned. They're great if you want a mixture of reference/examples. They cover a huge number of the libraries in the .NET framework, and also have great little example applications you can try too. Definitely worth having in your library.

I'm going to go slightly different here and recommend Jon Skeet's C# in Depth book. Have a look at Jon's site here[^].

Here are a few books that might assist you:
1. Sams Fluent CSharp 2011
2. Cengage C# Programming 2010 by Barbara Doyle
3. Microsoft Press Visual C# 2010 Step by Step
1. Is aimed at those with some .net, visual basic, C# exposure and speaks in patterns and english.
2. Is straightforward Application tutorial using C#
3. Is a comprehensive tutorial for beginners, one I reccomend.

Oh, and the pages says "Save 50% - In Celebration of TechEd North America" so I don't think I'm giving out a secret by passing on the code.

I have my web site ready for my UI person to pretty it up.
All I have left to do is write the web service for it so other web sites can use it.
I didn't think it would be this puzzling since I had seen that option before as a project template and I understand (at a high level at least) what SOAP is.
I've already coded using the web site with Entity Framework (which requires the .NET Framework 4.0) and the only web service examples I have been able to dig up say 'pick Framework 3.5' in the instructions.
As many articles as I've looked at I must be missing something. There has to be a way to do this without rewriting my search in Framework 3.5, right?
All I want to do is either return 0 or more records which have four strings (each) based on search criteria, or return a detail record if an id is passed.
So, it looks like EF4 is my brick wall.
Any hints how to go through/around it?
TIA,
-Chris C.

To create webservice in .Net 4.0, you need to create an asp.net web application project and then add a "web service" new item. With WCF in hand, do you really want to do that?
WCF can do much more than web service and faster.

I'll start with that thanks!
> With WCF in hand, do you really want to do that?
And... I can take a hint, so I've done some quick reading about how WCF is a 'service framework' and why that's superior to a web service (don't need a web server).
But one (possibly stupid) question:
Can it act as a Web Service? (I know it can run on a web server but that might not be the same thing)
This is only a critical question because the specification (written by a contractor that is no longer here) calls for a web service.
TIA,
-Chris C.

Yes. WCF is largely transport agnostic. The same code can serve up different transport types, merely by changing configuration, so you could have the same code simultaneously serving up via named pipes, TCP and HTTP without changing a single line of code.

See exactly what you want, if you have applications in other operating system using this service, better go ahead with webservice, otherwise, go with WCF, as in terms of performance, the webservice can't beat.
You also have lot of flexibility in WCF

I hope I don't bother anyone with my simple and newbie-look-a-like questions The title itself is clearly indicating what I want for the answer. So thanks for your help

In non technical teams the stack is an optimized memory bank that is very fast. The heap is a memory bank that isn't as fast but great for handling objects of varying sizes. So when you create an object, .NET looks to see if it is a native or reference type. If it is a native type, the value it put on the stack, otherwise it is put on the heap.
The reason for this is that the stack only handles objects that are 32 bits in size. The fact that all memory allocations are the same size is what makes it fast. Also it's not a pointer to a value that is stored, it's the actual value itself. Because of this Boolean values actually occupy 4 bytes of memory. Native types like doubles are stored in 2 x 4 bytes
A reference type like a string for example could be any size. It could also be very large. So what happens is the string is stored on the heap and a pointer is created and put on the stack so it can be found quickly. Either way, the combination offers a lot faster solution than a simple memory model.

Reason for my vote of one: (and I suspect for the others) Wrong. It is so completely wrong, that there is almost nothing in there that is actually correct.
I don't often give down votes, but I'm making an exception in this case!
Sorry, but you really need to go back to the beginning and start learning this stuff again.

I read Jeffrey Richter's book on CLR but I must have totally misunderstood what I was reading. Hopefully someone will explain the difference in this topic. At the moment I'm aware I've got it wrong. I just don't know why.

I understand what you are trying to say but I didn't have another choice and I thought this is the right place to ask that problem. I already excused for my question you consider non-advanced and unprofessional . I hope you realize why.

You do realise that OG wasn't addressing you don't you? What he was saying is that the answer you were given was wrong - not that you were stupid for asking the question. It's actually a pretty fair question, as the concepts are misunderstood, which you can see from the answers.

|

Yeah your right, I didn't recognize! Oops

No, no, you misunderstood - that was not directed at you or your question (which is a good, sensible question). That is why it was a reply to RobCroll and not to you, and why his answer is light grey, and yours is still blue.
His answer to your question was wrong in just about every respect, and what he said you should ignore - look at Dave Kreskowiak's answer which is much, much better. That is why I (and I suspect others) voted him down - the advice was bad. If you look at the bottom left corner of a message you will see a "rate this message" facility. Have a look at his answer: 1.71/5 (7 votes) indicating he has had seven ratings, and that they have generally been unhappy. A vote of one is a "this is bad", a vote of 5 is a "this is good". If your message has no votes, it is blue, if it is down voted, it goes grey. If it is upvoted it goes green.

The stack is (NOT OPTIMIZED VERY FAST MEMORY!) just an area in memory where various values are stored in a Last In, First Out fashion. It's used to hold simple variable values, pointers to objects, parameters for methods calls, return addresses for returning control back to where a method was called from, ...
A heap is a block of memory that contains both free (reserved for your app but unused) memory and allocated objects such as buffers, class instances, strings, or other complex types.

This uesd to be a lot easier question to answer - the stack was a small bit of RAM pointed to by the CPU Stack Pointer (SP) register, which made it fast and easy to access. Every CALL instruction pushed the current values in all CPU registers onto the stack, then popped them back when the CALLed routine was finished to resume execution. The Heap was a block reserved in RAM by an application to hold and access run-time data. Now it's a bit more complex, but this[^] discussion puts it in perspective.
