Visual Studio and .NET Framework Hotfix Public Availability Program

The goal of this program is to provide customers with direct access to the most popular Hotfixes for Visual Studio and the .NET Framework.

A Hotfix is a product update package with one or more updated product files that fix a specific product problem.

Below is a list of product issue descriptions and Hotfix download links for the most frequently requested Hotfixes.

Many of the Visual Studio 2005 Hotfixes are also available in Visual Studio 2005 Service Pack 1. More information about that service pack can be found on the Visual Studio 2005 Service Pack 1 Page.

If you have questions, please see the FAQ. If you have feedback on this program or the available Hotfixes please use the Visual Studio & .NET Framework Connect Feedback Site.

WARNING:
The Hotfixes available through this program have not gone through full Microsoft product regression testing. Specifically, these Hotfixes have had targeted testing which does not include testing in combination with other Hotfixes. You are encouraged to install only the Hotfixes needed to address the particular product problem you may have.

Please carefully review the associated Hotfix KB article to verify the fix is the one needed and there are no known compatibility or installation issues. You may also want to contact a Microsoft Support Professional.

I have a problem that is not addressed by a hotfix on this page… what now?
The list of hotfixes here is not the complete list of available solutions. To see if there is a solution to your problem you may want to search our KB articles. If you can’t find a solution you may want to contact Microsoft Support.

Why aren't all Visual Studio and .NET Framework hotfixes available on Connect?
The hotfixes listed on this page are the ones that have been most frequently requested since the launch of Visual Studio 2005. If you require a hotfix that is not available here please contact Microsoft Support directly. If you have a suggestion for a hotfix that should be available for download please leave that suggestion on the DevDiv Connect Feedback Site.

Can I redistribute this hotfix in my software?
Many of the VS hotfixes include redistributable files for your customers, however a License Request is currently required to do so. To obtain a license request you’ll have to contact customer support. However you can freely redistribute hotfixes within your own company without additional license.

Will other products, like Windows and Office, also make hotfixes publically available?
Several of the top requested Windows and Office hotfixes are already available to download via a link in the appropriate KB article. This site covers developer technologies so this is not the appropriate location to request or search for hotfixes for Windows or Office.
