The attached screenshot shows:
Resharper doesn't recognise the namespace 'Microsoft.Xrm.Sdk'
Resharper doesn't recognise 'Entity' which makes sense because it is part of that .net library
Visual studio can compile despite the errors that R# is bringing up
The references list clearly shows that the microsoft.xrm.sdk dll is being referenced
I'm using R# v6.0 (6.0.2202.688)
I'm using VS 10.0.40219.1
When you roll your mouse over the 'Sdk' portion of the using statement, R# says "Cannot resolve symbol 'Sdk', Active hotspot in live template session".
When you roll your mouse over the 'Entity' it says 'Cannot resolve symbol Entity'.
