CRM Toolbox to Connect to CRM Server

You install the developer toolbox to connect to CRM server to work with plugins and workflows. Sometimes after doing changes to the solution you do not see this.

If you need to get this back you need to change the solution file. You can do this by opening the solution file in notepad or notepad++ and adding the following line.

GlobalSection(CRMSolutionProperties) = preSolution
                SolutionIsBoundToCRM = True
EndGlobalSection

Once this is added to the solution, solution file will be reloaded and you will be able to see the toolbox again.
