Question

Answer 1

Try removing the role from the cloud project, re-build solution (if there are errors please post them), then add the role back into the cloud project and re-build.

Answer 2

I had a similar issue with VS2013 express after creating a view in my MVC project.

I reverted the project with git, but this did not solve the issue. I also checked the project out to a different location on my pc, but this did not solve the issue. I was able to check the project out on my laptop without seeing this issue.

In the end, I undinstalled VS2013 express and all of it's counterparts and re-installed. This solved the issue.

None of these answer helped me. I decided to reinstall the Azure tools, and noticed that I had more than one version installed. I uninstalled the old versions, reinstalled the latest version, and this fixed it for me.

Answer 4

You don't have to remove your roles and add them back in again, which is really annoying because you have to preserve the contents of your cscfg and csdef files. Instead, close Visual Studio, delete the solution's .suo file and open the solution back up again.

Answer 5

I wanted to let everyone know I was dealing with a very similar situation, albeit with a different version of the Azure SDK (1.8). I have many projects with Cloud Services that I have created built numerous times and then all of sudden could no longer open them. Attempting to open the Cloud Service configuration UI resulted in the “Object not set to a reference” error. I could open the actual XML file, but not the GUI interface.

I attempted to reinstall the 1.8 SDK and tools numerous times, as well as VS 2012 to no avail. I finally tried installing the latest SDK (2.2) and now I can open the projects. Not sure what changed in my system prior to this but glad I was finally able to open my projects again!
