Heads Up

SPDispose Check by Microsoft has been released[garb it here], and its a helpfull resource for checking the disposals in your code.

I created a bat file and now i run that bat in Open With and he checks that dll right there the bat is pretty simple:

@"SPDisposeCheck" "%1"

@pause

Be sure to have the spdisposecheck.exe in path or same directory.

Another goodie i really want to try out in a new project is SPConfigStore @

http://www.codeplex.com/SPConfigStore No more hardcoding? ;)

The SharePoint Config Store is intended for SharePoint developers, and provides the framework to be able to use a SharePoint list for application configuration values. This is useful when there are certain values used in a site or application's code, but we don't to hardcode them or even store them in web.config. Storing such values in a list means they can be easily updated (possibly by end users if you choose to allow this) without requiring access to the web server's filesystem.

Example config items for a SharePoint site/application/control could be:

'AdministratorEmail' - 'bob@somewhere.com'

'SendWorkflowEmails' - 'true'
