If you use the database schema compare tool in Visual Studio 2012 you may see the following error when trying to compare the database with the source:
Cannot access a disposed object. Object name: ‘ModelStore’
For me, this was arose after installing the June 2013 update 3 for Visual Studio 2012.
I resolved the error by running Clean Solution and rebooting my machine.
Hopefully this helps someone, as the error isn’t exactly helpful 🙂
Sometimes, when trying to create an alert in SharePoint you receive the following error message:
You do not have an e-mail address.
Alert has been created successfully but you will not receive notifications until valid e-mail or mobile address has been provided in your profile
The obvious things to check here are the outgoing mail server settings in Central Administration.
It may be the case that you recently added an email address to the account in question, or after receiving the above error added an email address to the user’s profile in Central Administration.
