I opened a visual studio CRM 2011 solution and got the message
“No Organization has been specified”
hmmm, I thought and then annoyingly I wasn’t able to add an organisation because the CRM Explorer toolbar was greyed out and inactive.
After sniffing around the files and the internet I found this forum post
So I moved the SUO file and then started visual studio again.
This time it asked me to fill in the CRM details and I could setup a link to the correct CRM Organisation.
