  48 // Basically there are two semantic Project object models and their relationship is not obvious
  49 // (apart from Microsoft.Build.Construction.ProjectRootElement which is a "construction rule").
  50 //
  51 // Microsoft.Build.Evaluation.Project holds some "editable" project model, and it supports
  52 // detailed loader API (such as Items and AllEvaluatedItems).
  53 // ProjectPoperty holds UnevaluatedValue and gives EvaluatedValue too.
  54 //
  55 // Microsoft.Build.Execution.ProjectInstance holds "snapshot" of a project, and it lacks
  56 // detailed loader API. It does not give us Unevaluated property value.
  57 // On the other hand, it supports Targets object model. What Microsoft.Build.Evaluation.Project
  58 // offers there is actually a list of Microsoft.Build.Execution.ProjectInstance objects.
  59 // It should be also noted that only ProjectInstance has Evaluate() method (Project doesn't).
  60 //
  61 // And both API holds different set of descendant types for each and cannot really share the
  62 // loader code. That is lame.
  63 //
  64 // So, can either of them be used to construct the other model? Both API models share the same
  65 // "governor", which is Microsoft.Build.Evaluation.ProjectCollection/ Project is added to
  66 // its LoadedProjects list, while ProjectInstance isn't. Project cannot be loaded to load
  67 // a ProjectInstance, at least within the same ProjectCollection.
  68 //
  69 // On the other hand, can ProjectInstance be used to load a Project? Maybe. Since Project and
  70 // its descendants need Microsoft.Build.Construction.ProjectElement family as its API model
  71 // is part of the public API. Then I still have to understand how those AllEvaluatedItems/
  72 // AllEvaluatedProperties members make sense. EvaluationCounter is another propery in question.
