IDisposable Thoughts

Today I need something really particular with NHibernate, I need to generate a “test” database schema from my MSBuild task in a particular Target. I know, there are simple options like use hbm2ddl (part of the NHibernate distribution) and this simple Mike Nichols’ MSBuild task but I want to use the hibernate configuration file.

This is my first attempt to do this in a MSBuild task, write this task in MSBuild was a very trivial code exercise, I need to improve it and get more things done, but right now I think is enough to get the job done.

The usage is very simple:

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"
    DefaultTargets="Test">
  <PropertyGroup>
     <NHibernateConfig>hibernate.cfg.xml</NHibernateConfig>
  </PropertyGroup>
  <ItemGroup>
    <TestDatabase Include="./test.db" />
  </ItemGroup>
  <UsingTask AssemblyFile="../bin/Rioshu.Msbuild.dll"
        TaskName="NHibernateSchema" />
  <Target Name="Test">
    <Delete Files="@(TestDatabase)"
        Condition="Exists('@(TestDatabase)')" />
    <NHibernateSchema ConfigurationFile="$(NHibernateConfig)"
        Export="true" />
  </Target>
</Project>
