Dear Developers --
Please help.
The Visual Studio 2012 code window seems like it loses project-based references upon file opening.
Here are the details.
I am using Visual Studio 2012, on Windows 7, all fully-patched, writing in C#.
The Soltion is simple-- just 4 projects-- MyEntities, MyDataModel, MyBusinessComponents, MyServices (WCF-style service layer).
All projects target ".NET Framework 4.5", and all use Project-based references to each other, variously pointing to each other when necessary, in a typical way.
All other referneces are GAC-based references pointing to built-in .NET Framework Assemlies, so there are no 3rd party DLLs involved, etc.
(1). Open Solution, Close All Documents, Clean Solution, Rebuild Solution, and AOK.
(2). Open code file in the editor, and BOOM, red-squiggle errors appear under code lines that point to other projects in the same Solution, build fails.
Usually, it does seem to "go away", after a few failed Solution builds and/or after a successful Start Debugging runs.
But it tends to come back later, losing all IntelliSense, causing great concern, killing efficiency, shaking confidence in the IDE, and etc.
Is there a fix or a workaround for this?
Please advise.
Thanks.
