Question

The book says about a small Windows.Forms program

The Windows Forms classes are in the
System.Windows.Forms assembly, which
is the System.Windows.Forms.dll file.
To compile this program you need a
reference to that assembly.When compiling
on the command line, use the /r switch to specify other assemblies.

But I am able to compile this program from the command line(csc.exe) just fine, without having to reference to any assembly. why is this ?

Answer 1

csc defaults to adding references to a bunch of assemblies. Have a look at csc.rsp in the same directory as csc.exe (e.g. c:\Windows\Microsoft.NET\Framework\v3.5) to see what’s referenced by default.

You can specify your own response file with an @ like this:

csc @responses.txt Foo.cs Bar.cs

(This isn’t useful very often, admittedly…)

You can also prevent the default response file from being used with the /noconfig switch.
