Quiero perfilar y ajustar nuestra construcción con la esperanza de ahorrar unos segundos aquí y allá. Yo era capaz de crear una tarea que se deriva de ResolveAssemblyReferences y utilizarla en su lugar, pero estoy teniendo problemas para entender lo siguiente (de Microsoft.Common.targets): se pasan¿Cómo funciona ResolveProjectReferences?
<!--
============================================================
ResolveProjectReferences
Build referenced projects:
[IN]
@(NonVCProjectReference) - The list of non-VC project references.
[OUT]
@(_ResolvedProjectReferencePaths) - Paths to referenced projects.

When building this project from the IDE or when building a .SLN from the command-line,
just gather the referenced build outputs. The code that builds the .SLN will already have
built the project, so there's no need to do it again here.
The ContinueOnError setting is here so that, during project load, as
much information as possible will be passed to the compilers.

Algunos parámetros y algunos se devuelven , pero ¿dónde sucede el trabajo real? No hay mucho en msdn: he encontrado Microsoft.Build.Tasks.ResolveProjectBase, pero no sirve de mucho.
Entonces, si resulta que la etapa ResolveProjectReferences está tomando cantidades significativas de tiempo durante una compilación, ¿eso es efectivamente porque el proyecto está bloqueado, esperando o se va a crear una dependencia? No he podido encontrar ninguna documentación clara sobre esto. No está claro si este es el tiempo dedicado a identificar y localizar dependencias (trabajo real), o el tiempo empleado esperando que las dependencias estén disponibles (tiempo de inactividad efectivo) – jalf
Su mejor opción es construir en el nivel de verbosidad de diagnóstico. Eso le mostrará exactamente lo que hace cada objetivo (incluidas las construcciones anidadas), así como los tiempos para muchas operaciones. – tintoy
