Eu estou fazendo o seguinte:

Eu criei um projeto de arquivo de classe padrãoEditei o arquivo csproj para incluir o Pre e o Post BuildEventsUncomment o padrão comentou alvos BeforeBuild e AfterBuild

Os alvos BeforeBuild e AfterBuild não são chamados de formulário no Visual Studio, mas são da linha de comando msbuild, por que isso?

Eu preferiria usar alvos msbuild em vez do PostBuildEvent como se me desse mais poder e flexibilidade, assumindo que funciona.

Felicidades,

Adão

Eu encurtei alguns dos caminhos na saída, então se eles são inconsistentes é por isso

Alterações de ClassLibrary1.csproj

<code><Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
<Target Name="BeforeBuild">
  <Message Text="### BeforeBuild ###" />
</Target>
<Target Name="AfterBuild">
  <Message Text="### AfterBuild ###" />
</Target>
<PropertyGroup>
  <PreBuildEvent>echo PRE_BUILD</PreBuildEvent>
</PropertyGroup>
<PropertyGroup>
 <PostBuildEvent>echo POST_BUILD</PostBuildEvent>
</PropertyGroup>
</code>

minha saída de compilação do VS 2010 é

<code>------ Rebuild All started: Project: ClassLibrary1, Configuration: Debug Any CPU ------
PRE_BUILD
ClassLibrary1 -> c:\ClassLibrary1\bin\Debug\ClassLibrary1.dll
POST_BUILD
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
</code>

e da linha de comando
