Roslyn is a platform which provides the developer with powerful tools to parse and analyze code. It's not enough just to have these tools, you should also understand what they are needed for.
The article can be divided into 2 logical parts:
General information about Roslyn. An overview of tools provided by Roslyn for parsing and analyzing the code. We provide a description of entities and interfaces, as well as the point of view of a static analyzer developer.
Peculiarities that should be taken into account during the development of static analyzers. Description of how to use Roslyn to develop products of this class; what should be considered when developing diagnostic rules; how to write them; an example of a diagnostic.
This article is intended to answer these questions. Besides this, you will find details about the static analyzer development which uses Roslyn API.

You are so lucky to be a programmer. I would like to be the programmer.
- Why do not you learn?
- I already tried. I checked out codeacademy and other websites, but it is not mine.
- Yep, the programming is not really for everyone.
- You are well paid, and you can create different things. Almost every day you get some crazy offers at least for 100 thousand dollars.
- Yep, honestly it's very flattering and a little mind-blowing.
- You get your share in the company and you know that the software engineers are always respected. You can implement any idea in the app and get rich. Moreover, you do not need to hire anyone for this.
- Actually, the programming makes me miserable.
- Wow. What do you mean by that?
- In order to be a good programmer, I need to develop a special mindset and that makes me sad. I noticed this in other programmers, of course, not all, but in many.
- What is this mindset?
- This is concentration on the strengths, and not on the weaknesses.
- Why do you need this to become a good coder?
- I work like this:
Presently, the distance learning system has been developing all the time. There is no longer a problem to get a good education remotely. Online learning has several advantages, such as learning at own pace, freedom and flexibility, accessibility, and social equality. The Web offers a variety of services to help gaining new knowledge.
A couple years ago, I worked together with Ken Thompson on the interactive graphics language that was developed by Gerard Holzman in Bell Labs. I was typing quicker, therefore, I sat at the keypad, and Ken stood behind me. We worked quickly and when the compiler gave out an error, I started reflexively digging in a problem, studying the call stack, program output and launching a debugger, and so on. But Ken simply was standing nearby and thinking, ignoring me and a code, which we just wrote. Soon I noticed regularity that Ken often understood the problem faster than me and was saying, “I know, what is going on”. Usually, he was right. I understood that Ken built the mental model of a code, and when something was broken, it was the error in this model. He was thinking of how this problem could arise, so he explained what was wrong with model, or where our code could mirror this model incorrectly.
Today, I am going to talk about how you can hide the “spare" assembler commands in the regular code. This method is useful for complexity of disassembling the code, especially if the generation of "hidden" commands to automate. Tools: debugger - OllyDbg.
Over a year ago one user of StackOverflow programming site asked for help concerning this issue. Namely, they have the employee with the last name Null at the firm. The problem is that because of his name falls a corporate search application, if the employee’s name will be used as search query (it has happened very often recently). Error:
<faultstring>coldfusion.xml.rpc.CFCInvocationException: [coldfusion.runtime.MissingArgumentException : The SEARCHSTRING parameter to the getFacultyNames function is required but was not passed in.]</faultstring>
I have little experience (summarily I have been working as a programmer nearly for 16 months), nevertheless, I would like to give some tips to myself in the past, or in other words, to those who are studding now at the university and planning to become a software developer. I do not have a claim on wisdom or experience on no account. While thinking a little, I understand that all these tips are very actual for me more than ever too. I published the first note in my blog last year, and now I am publishing here the list expanded with tips of the readers of this blog.
All tips are independent and their order does not matter.
The recent Visual Studio 11 Beta version has a new and major built-in feature of the future C # 5 - asynchronous programming using async/await. In this article I would like to structure and examine this quite interesting new tool and share the results with you.
Why is it needed?
C# is actively developing language. Each its version has interesting features that really simplify the writing quality of understandable code. For example, Linq considerably simplified the writing of filters for collections and sql queries in the code. Now the turn came for asynchrony.
1. Learn a new programming language
Learning the new programming language will develop new ways of thinking, especially if the new language uses a paradigm that you do not know yet. Many of the acquired ways of thinking could be applied to the languages that are already known. Perhaps, you might even like the new programming language, and you will start using it for new serious projects.
Here are some good languages that give the great educational experience and cognitive effect: Lisp (Scheme is good), Forth, PostScript or Factor (stack-oriented programming languages), J (wonderful array programming language), Haskell (strongly typed purely functional programming language), Prolog (logic programming) and Erlang (concurrent programming goodness).
2. Read a good programming book
A lot of knowledge could be found in the books. Undoubtedly, a practice is also important, but reading one challenging programming book might help you to challenge your thinking and to enrich your knowledge. Here is a list of such challenging books: The Art of Computer Programming (if you want a real challenge), Structure and Interpretation of Computer Programs (SICP), A Discipline of Programming or the famous dragon book.
Of course, you can read less complicated books as well, but you try to go around books such as “For Dummies” that promise to teach you in 24 hours or 3 weeks. These books will not do any good for you in terms of improving programming skills.
Here are some comments about time:
- UTC: The time at the Prime Meridian is called Universal Coordinated Time (UTC). A mismatch was caused by the acronym of its universal necessity for all languages.
- GMT: Before UTC was called Greenwich Mean Time (GMT), because the Prime Meridian was chosen to pass through the Royal Observatory in Greenwich.
- Other timezones can be written as an offset from UTC. For example, Australian Eastern Standard Time is written UTC+1000, namely 10:00 UTC is 20:00 EST on the same day.
- Summer time does not affect UTC. It's just a political decision to change its time-zone (offset from UTC). For example, GMT is still used: it's the British national time-zone in winter. In summer it becomes BST.
- Leap seconds: By international agreement, UTC is kept within 0.9 seconds of physical reality (UT1, which is a measure of solar time) by introducing a "leap second" in the last minute of the UTC year, or in the last minute of June.
- Leap seconds are not required to be declared (by astronomers) more than 6 months prior to their introduction. This presents a problem if you need any planning with second accuracy for more than 6 months.
