I have been enjoying the highly useful services and friendly user-interface that DotNetDuke provides and I'm more that happy to advise my friends to try it out. I had another post regarding an issue I have been stuck working on.
The following is how my NANT Build File looks like:
<?xml version="1.0"?>
    <project name="nant" default="build" basedir=".">
         <description>nant build files.</description>
        <property name="debug" value="true" overwrite="false" />
        <target name="clean" description="remove all generated files">
            <delete file="nant.exe" fail ="false" />
            <delete file="nant.pdb" fail ="false" />
        </target>
        <target name="build" description="compiles the source code">
            <csc target="exe" output="nant.exe" debug="${debug}">
                <sources>
                    <include name="nant.cs" />
                </sources>
     </csc>
        </target>
    </project>

Everytime I try to run it in Visual Studio 2008, I get the following error message:

build:

[csc] Compiling 0 files to 'C:\websites\dnn492_9\nant.exe'.

[csc] fatal error CS2008: No inputs specified

BUILD FAILED

C:\websites\dnn492_9\nant.build(10,14):

External Program Failed: c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe (return code was 1)

Please, I need a feed back about my build file and any related mistakes that might caused this error meassage to pop up.

Your time and support is highly appreciated.
