Just would like to make clear, I cannot find straight answer. C# is general specification of this language done by MS, while Visual C# is implementation of this language, again done by MS?
So if we say we develop in C# (in visual studio e.g.) we develop in Visual C# actually.
Is that correct?
Yes, you've pretty much got it. Most of us just refer to it as C# though, since it is after all a Microsoft thing, and their implementation of the language is what most coders use (in Visual Studio).
An example of a C# compiler that is not Visual C# is the Mono compiler. The IDE that uses that compiler is MonoDevelop. Both are not Microsoft products, but do implement the C# programming language (as well as the CLR).
I don't think that "Visual C#" is a particularly commonly used term - C# is the language, so I would probably say that "Visual C#" refers just generally to C# development using the Visual Studio suite of products.
Like I said though it's not a commonly used term any more (and as you have pointed it out it is also a somewhat confusing term).
You can say that Visual C# is the tool that is part of Visual Studio, provided my Microsoft used to create programs in the C# language.
There is the ECMA-334 C# Language specification, that defines the language.
There are other tools to create programs in C#, like SharpDevelop or MonoDevelop.
This whole "visual C#" has caused me much unnecessary grief (including one during an interview , given I had never heard of the term 'visual C#' and apparently the interviewer didn't even know what it was and was just trying to put checkmark beside qualifications). To sum, Visual C# doesn't exist. It's just C#, we should file a petition to remove that stupid qualifier.
Visual C# is the name of compiler (and IDE). C# is the language. It is the same as Borland C++ and C++ (first is the specific compiler). Or MySQL and SQL.
For all the answers that "Visual C# is C# developed in Visual Studio" - I would point out that the C# Compiler (CSC.EXE) is not part of Visual Studio but is delivered as part of the Microsoft .net Framework - which is completely independent of the Microsoft Visual Studio line of development tools.
In that it has any meaning at all (beyond the initial marketing idea that it would appeal to Visual Basic developers, who were the majority of Windows developers on launch day) I'd say it refers to C# compiled by the Microsoft implementation of the .net Framework.
Whether or not Roslyn compiles "Visual C#" or "C#" is anyones guess.
C# is a kind of programming lang, something like Java, Ruby, Python.
Visual C# means Microsoft Visual Studio/C#， it's IDE for programming C#.
u also can write C# code in notepad.

I have been trying to find out if Talend Open Studio has a scripting language. I hope that maybe it would be Perl or Python.
I have been using Microsoft SSIS ETL tool, and they have a Script-Component to handle more complex ETL tasks.
The SSIS Script-Component uses the languages C# and VB.NET as its scripting language.
Does Talend Open Studio have an equivalent to MS-SSIS Scripting Component.
I could not find much on the web on this.
The amount of material available for Talend Open Studio is very little.
Hope someone can shed some light on this.
Talend (Open Studio or Entreprise editions) is built on Java, and enables you to implement complex tasks in Java using tJava, tJavaRow and tJavaFlex components, as well as custom Java routines. You can also build your own custom components using XML to describe components, and javajet to generate the actual Java code.
Earlier versions of Talend (up to version 4) had Perl support, but it's been deprecated.
I'm not a professional or anything, just doing this for fun. Is there a free software suite for web development that would be better to use rather than using notepad++?
For example, I'm learning android development and I use android studio for it.
Thanks
One option for you to consider is Microsoft's new offering, Visual Studio Code.
It's basically a free version of Visual Studio designed to be cross platform (Mac, Linux, Windows) that currently best serves ASP.NET and NodeJS.
I'd consider giving it a shot. I haven't tried it because I use Visual Studio Professional 2013 for work, which is very fully featured. But VS Code will do syntax highlighting for these:
Batch
C++
Clojure
Coffee Script
DockerFile
F#
Go
Jade
Java
HandleBars
Ini
Lua
Makefile
Markdown
Objective-C
Perl
PHP
PowerShell
Python
R
Razor
Ruby
Rust
SQL
Visual Basic
XML
As well as Intellisense (like autocomplete, I believe) for these:
CSS
HTML
JavaScript
JSON
Less
Sass
It looks like it also has some sort of built in Git support, which would be really handy. Probably worth at least considering.

When I press Alt+F11 I get the *'Microsoft Visual Basic for Applications'* and I can start a module. This module seems to be in Visual Basic 6.0. How can I instead write Visual Basic .NET ? Can I do it from the same window?
You are looking at VBA not VB6, though the syntactic differences are small.
VBA is a scripting language for Microsoft applications.
As the comment to your question states, you would need to write a .NET assembly separately and interface with it via VBA.

So, I have an application consisting of an executable (exe) file and a DLL. Is there a way I can find out the specific language used to develop this software. I tried opening it in a disassembler but the contents seems garbled. Any ideas?
In principle, the answer is no. In practice, however, there are only a few choices:
If the .dll name looks like something.dll, it's probably a native dll image, which means it was probably written in C or C++.
If the dll name looks like Namespace.Something.dll, it's probably a managed dll, which means it was written in some .NET language (C#, VB.NET, etc.)
You can check the dll imports for more information. If the dll uses mscoree.dll then it's a .NET dll (even if it doesn't follow standard .NET naming conventions). It may also use other language-specific dlls that provide additional clues.
Open the .dll or .exe in a hex editor and search for the word "copyright". Most compilers put the copyright message of the runtime library into the executable in clear text.
Get IDA pro. http://www.hex-rays.com/idapro/ That is the tool to work with binaries or do reverse engineering. It will be able to find out the runtime library and maybe also the language.
Evaulation and freeware versions of the tool can be found here: https://www.hex-rays.com/products/ida/support/download.shtml
Unlikely, unless it has a significant runtime library that gives it away. e.g. VB apps used to require a huge DLL with VB in the name, Visual C++ apps usually require the C++ runtime to be installed. But modern languages target language-independent runtimes. Even Java .class files may have come from a wide variety of source languages.
ASP is a Compiled Language or isnt it? sure it is.
PHP is a Interpreted Language.
I also developed once an asp app with the VS 2008 IDE.
But there is a Big difference between ASP and PHP.
What are the Differences?
ASP is a Compiled Language or isnt it? sure it is.
No, it isn't.
The first reason why ASP is not a compiled language is because there is no such thing as a compiled language. A language is neither compiled nor interpreted. A language just is. A language is a bunch of abstract mathematical rules. Interpretation or Compilation are traits of a language implementation, they have nothing to do with the language. Every language can be implemented by either a compiler or an interpreter; most modern high-performance language implementations actually use both and switch between them depending on which one is faster in a particular context.
The second reason why ASP is not a compiled language is because it is not a language. It is a framework. You can write code for ASP in any language for which an ActiveScripting engine exists (e.g. Ruby via ActiveRuby), but most commonly one would write code in either VBScript or JScript.
Which brings us to the third reason: The implementations of VBScript and JScript that ship with Windows, as well as ActiveRuby and all other ActiveScripting engines that I know of, are pure interpreters, they cannot compile. So, even though I wrote above that any language can be implemented using either a compiler or an interpreter, all the language execution engines that are supported by ASP are interpreted.
PHP is a Interpreted Language.
Again: no, it isn't.
Reason one is the same as above: there simply is no such thing as an interpreted language.
And, in contrast to ASP, the vast majority of PHP implementations actually do contain a compiler. Some even are pure compilers, they don't even have an interpreter. (Phalanger, for example always compiles straight to CIL, with no interpretation whatsoever. P8 can either interpret or compile straight to JVM bytecode or both: interpret, gather profile data while interpreting and then JIT-compile to JVM bytecode.)
But there is a Big difference between ASP and PHP. What are the Differences?
ASP is a (language-independent) framework, PHP is a language. That's a rather big difference. (Actually, PHP contains one small bit that would in other languages usually considered to be part of a web framework: webserver integration.)
PHP is highly portable across operating systems, CPU architectures and webservers: there is a PHP implementation for nearly every execution environment, from the JVM to the CLI to Parrot to running natively on pretty much every operating system under the sun. ASP is pretty tightly bound to Microsoft Internet Information Server, Microsoft Windows and the PC platform. (There were some other implementations but they are pretty obscure and no longer available.)
PHP has lots of different implementations (Phalanger, Quercus, Pipp, PHC, P8, Zend), ASP has only one. (Like I said, the two other ones are no longer available.)
The vast majority of PHP implementations are Open Source (I think the only exception is P8), while all three ASP implementations that I know of are proprietary.
PHP is actively developed and maintained, whereas ASP is largely obsolete and has been superseded by ASP.NET.
You could be more specific with your question.
The biggest difference is of course that ASP is programmed in a .NET language and uses the .NET framework as a basis. PHP of course is programmed in PHP and with it's library.
.NET is compiled into bytecode and that bytecode is interpretted/jitted at runtime. There are also bytecode caches for PHP (e.g. APC) and there is an active project that aims to generate native code from it using LLVM.
ASP is interpreted ASP.NET is compiled. ASP is not a language but a framework, you can code ASP.NET in a bunch of languages. ASP.NET runs only on IIS (unless you use Mono and who remembers Chilisoft ASP here?)
I have noticed when trying to add hosting on GoDaddy.com, PHP is for a Linux package and ASP was for Windows package.
ASP is a proprietary, closed-source implementation, PHP is not.
