Question

In Visual Studio 2010 I’ve upgraded a cloud solution to Windows Azure SDK 1.8 and Windows Azure Tools October 2012 (previously I was using version 1.7 and June 2012 tools). This solution is composed of several cloud projects for different purposes (debug, test, deployment, …): I first updated a cloud project and when I finished testing the various roles in the compute emulator I updated the remaining projects.

I then noticed that when I package the latter projects I receive the error

The XPath provided is not valid 'csc:ServiceConfiguration/@osFamily'. Namespace prefix 'csc' is not defined.

in file C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Windows Azure Tools\1.8\Microsoft.WindowsAzure.targets

Instead if I package the first updated project everything is fine.

I’ve tried the following:

• since I changed the osFamily to 3 (Windows Server 2012), I though it was somehow incompatible and I reverted it to 2 (Windows Server 2008 R2) — but the error remains;
• I tried to compare one of the failing project with the working one, but I spotted no relevant difference.

Answer 1

I resolved the issue by creating a new cloud project from scratch and manually “importing” the configuration from the old project (csdef, cscfg and Project References section in ccproj file). From this new project the package operation completes correctly.
