Re: c# compiler selection for the <script> task

Hi Liam,

 

We use CodeDOM to compile the script, and hence it uses the C# compiler
corresponding to the CLR on which NAnt is running.

The current target framework - as specified using the
nant.settings.currentframework - does not affect this.

 

I'd appreciate it if you'd submit a (documentation) bug report for this.

 

Hope this helps,

 

Gert

yeah, that is odd.  I cannot get var to work. 
I changed my .config file settings as well to point to 3.5, but still
getting an error.

Sorry for unclear explanations... For example, this code returns an error:

<project name="Test" default="run">
    <property name="nant.settings.currentframework" value="net-3.5" />
    <target name="run">
        <script language="C#" mainclass="Test">
            <code>
                <![CDATA[
                    class Test {
                        public static void ScriptMain(Project project) 
                        {
                            var s = "Hello world";
                            Console.WriteLine(s);
                        }
                    }
                ]]>
            </code>
        </script>
    </target>
</project>


Buildfile:
file:///c:/_nant-0.91-alpha2/examples/ScriptTask/script-sample.build
<file:///c:\_nant-0.91-alpha2\examples\ScriptTask\script-sample.build> 
Target framework: Microsoft .NET Framework 3.5
Target(s) specified: run

BUILD FAILED

Compilation failed:
[...]\Temp\h7ph1r09.0.cs(27,29) : error CS0246: The type or namespace name
'var' could not be found[...] 

I don't understand why it happens. Framework is changed to 3.5 but script
code is compiled using csc v2.0.

I am not exactly sure what you are asking, as your post is a bit unclear. 

if you want to use C# 3 features in your app, make sure you have the proper
version installed and your app is referencing them.  In addition, this
listserv is not the proper place to post this question. 

if you want Nant to reference a version of the framework that uses C#3 and
allows the var keyword, make sure you are referencing the correct framework
in your Nant.exe,.config file in your bin directory.

Hi all,

I want to use c# 3.0 features ("var" keyword, for example). But if I use it
in the <script language="c#"> task then I got compilation error. How I can
select c# compiler version there?

Thanks in advance!
