SPDisposeCheck v1.3.1 is released

  • Article

SPDisposeCheck is a tool to help SharePoint Developers follow memory management best practices when using the SharePoint API with IDisposable objects including SPSite and SPWeb. This tool is not supported by Microsoft and is recommended to be used on Developer workstations and not on production SharePoint Server installations.

It was released yesterday at https://code.msdn.microsoft.com/SPDisposeCheck

The tool reviews a .NET Assembly (DLL or EXE) and evaluates SharePoint API's used in that assembly. It will produce a report identifying where code doesn't follow best practices for memory management in SharePoint. It may not find all memory leaks in your code and it may produce false positive results but it does it much faster than you can review source code yourself. The tool checks for guidance published in an update to the MSDN Article (Best Practices: Using Disposable Windows SharePoint Services Objects) that describes the best practices for this area of SharePoint development. This guidance applies only to customers building custom software that they compiled to .NET assemblies that make use of SharePoint API calls. While these messages need expert evaluation in order to determine if the software is not performing properly, in some cases just running the tool on your custom code can lead you to simple fixes that improve the quality and performance of custom code on SharePoint. Customers who are currently experiencing difficulties with memory management in their custom applications should review the guidance listed above. Customers who are currently experiencing difficulties with Microsoft Office SharePoint Server 2007 should contact their regular Microsoft Customer Support Services contact, or refer to https://support.microsoft.com.

note: The MSDN article hasn't been updated at the time of the blog post. The MSDN article should be updated in the next 24 hours. 

You are encouraged to discuss usage of this tool on the SharePoint Developer MSDN Forum. You can also provide feedback directly on the CODE.MSDN site for SPDisposeCheck where we published it. We value your feedback on how useful this tool is.

We plan to use Roger Lamb's blog as a place to update the latest guidance for specific cases that come up.

    I think there should be a "SPDisposeCheck Certified" logo.  This badge could be placed on the download pages and in the documentation of both free software and commercial software products as an indication of quality and adherence to best practices.

    I found it interesting that SPDisposeCheck ignored files and namespaces that started with Microsoft and System. With a little bit of reflection I managed to come around the “problem”: Microsoft.SharePoint.dll 9 Microsoft.Office.Policy.dll 1 Microsoft.Office.Server.Search.dll 1 microsoft.sharepoint.portal.dll 2 Microsoft.SharePoint.Publishing.dll 10 Microsoft.SharePoint.Search.dll 1

    Hi there, ive just develop a wrapper to use with SPDisposeCheck Tool, that displays Xml with errors if so, and its to be used on VisualStudio postbuild events to prevent bad disposal of Moss objects. I hope it helps someone in a need. http://www.codeplex.com/MossSnips2 Best Regards Scoutman, a portuguese connection Rodrigo Pinto, Sharepoint Solution Architect email:stationsolutions@gmail.com im:workstationpt@hotmail.com
