All Implemented Interfaces:
SelectorContainer
public class CSharp
extends MatchingTask

Compiles C# source into executables or modules. The task will only work on win2K until other platforms support csc.exe or an equivalent. CSC.exe must be on the execute path too.

All parameters are optional: <csc/> should suffice to produce a debug build of all *.cs files. References to external files do require explicit enumeration, so are one of the first attributes to consider adding.

The task is a directory based task, so attributes like includes="*.cs" and excludes="broken.cs" can be used to control the files pulled in. By default, all *.cs files from the project folder down are included in the command. When this happens the output file -if not specified- is taken as the first file in the list, which may be somewhat hard to control. Specifying the output file with 'outfile' seems prudent.

TODO

  1. is incremental build still broken in beta-1?
  2. is Win32Icon broken?
  3. all the missing options

History
0.3 Beta 1 edition To avoid having to remember which assemblies to include, the task automatically refers to the main dotnet libraries in Beta1.
0.2 Slightly different Split command execution to a separate class;
0.1 "I can't believe it's so rudimentary" First pass; minimal builds only support;

Since:
Ant 1.3
Version:
0.5

Field Detail

DEFAULT_REFERENCE_LIST


protected static final java.lang.String DEFAULT_REFERENCE_LIST
Fix C# reference inclusion. C# is really dumb in how it handles inclusion. You have to list every 'assembly' -read DLL that is imported. So already you are making a platform assumption -shared libraries have a .dll;"+ extension and the poor developer has to know every library which is included why the compiler cant find classes on the path or in a directory, is a mystery. To reduce the need to be explicit, here is a long list of the core libraries used in Beta-1 of .NET ommitting the blatantly non portable (MS.win32.interop) and the .designer libraries. (ripping out Com was tempting) Casing is chosen to match that of the file system exactly so may work on a unix box too. there is no need to reference mscorlib.dll, cos it is always there
