Details of an Intellisense bug that affects Windows Workflow Foundation projects that reference Portable Class Library assemblies.
Raw
VS2012And2013WorkflowPCLReferenceIntellisenseBug.md

Description

Referencing a Portable Class Library (PCL) assembly from a Windows Workflow project results in loss of Intellisense on what appears to be all other assembly type data except from mscorlib.dll, including project referenced assemblies.

Repro

  1. Create a new Windows Workflow Foundation Console Application project.
  2. Add a PCL library such as TPL Dataflow (Install-Package Microsoft.Tpl.Dataflow) or Reactive Extensions (Install-Package Rx-Main).

Expected Result

All Intellisense features continue to function normally.

Actual Result

  • Syntax highlighting of non-mscorlib types stops working.
  • Intellisense suggestions for non-mscorlib types not provided.
  • F12 (Go to definition) doesn't work for any non-mscorlib types.

NOTE: this is a bug in VS2012 as well.
