<p>We are working on an inquiry management system using J2EE. We're looking at a feature, allowing users to send inquiries to particular mail-id and entering into the database. Catch is to automatically allocate it to some categories. </p>

You'll notice that the docs indicate that NAnt's
```
<solution
```
>
task doesn't support solution files newer than VS2003.
I recommend using
the
```
<msbuild>
```
task from nantcontrib
for all projects newer than VS2003.
Also, the .85 version of NAnt only supports framework versions up to 2.0. The purest way to get things working against the 3.5 framework is to use the
.86-beta1
versions of NAnt. You'll then be able to use the
```
<msbuild>
```
task against the 3.5 solution.
