#error is the preprocessor directive which produces compile time error messages. These directives are most useful for detecting programmer inconsistencies and violation of constraints during preprocessing.

CorDBG - command-line debugger.  To use CorDbg, you must compile the original C# file using the /debug switch.                                                                                                                                 DbgCLR - graphic debugger.  Visual Studio .NET uses the DbgCLR.

Compile it with the /doc switch.

ASP stands for Active Server Pages. ASP is an open, compile-free application environment in which you can combine HTML, scripts, and reusable ActiveX server components to create dynamic and powerful Web-based business solutions. Active Server Pages enables server side scripting for IIS with native support for both VBScript and JScript. ASPs are Web pages that contain server-side scripts in addition to the usual mixture of text and HTML tags. Server-side scripts are special commands you put in Web pages that are processed before the pages are sent from the server to the web-browser of someone who's visiting your website. All ASP pages are given a .aspx extension. The servers that support ASP are Internet Information Server (IIS) & Microsoft Personal Web Server. Unline normal HTML pages you can view ASP pages without running a web server. When a ASP.net page is compiled it's translated into MSIL.

The idea behind inline functions is to insert the code of a called function at the point where the function is called. If done carefully, this can improve the application's performance in exchange for increased compile time and possibly (but not always) an increase in the size of the generated binary executables.

A name clash occurs when a name is defined in more than one place. For example., two different class libraries could give two different classes the same name. If you try to use many class libraries at the same time, there is a fair chance that you will be unable to compile or link the program because of name clashes.

when you use WSDL.exe to compile a web service the following 2 steps are done: 1) A new proxy is generated for your web service 2) Web service is compiled into .cs file (You can view it to check out the client
   code) Now you have to compile your cs file into dll file so you can make
   reference to it. THis can be done by running the following command in
   VS prompt: csc /t:Library myservice.cs
3) Then .cs file it is converted into .Dll But if you are using VS Dot Net then
   these 2 steps are done automatically

A proxy class is a class that implements a list of interfaces specified at compile time. The proxy object typically holds a reference to an internal object that implements the same interfaces (or parts of them).

C compiler was written in C language,that is true.But that does not say in what language first C compiler was written.I think first C compiler might have used assembly language instructions.And after that further compilers might have used this(or other compilers that was built the same way) compiler to compile the other newly build compilers.
