Ctrl-S in web.config in Visual Studio closes web.config file

Ok a couple of weeks ago I started having some strange behavior in Visual Studio: Whenever I've been editing web.config in Visual Studio and then press the Ctrl-S key to save the file the web.config file closes. This is pretty annoying if you're working with the web.config file a lot as I do <s>...

Anyway, according to Omar Khan from Microsoft it turns out the problem is due to a bug in the ADO.NET Entity Framework Designer Tools, which I had installed shortly after installing the ASP.NET 3.5 Extensions that include the ADO.NET Entity framework. The tools are a seperate install from the ASP.NET 3.5 Extensions and they are responsible for providing the diagramming support in Visual Studio. Uninstalling just the Designer Tools solves the web.config issue. This will be fixed in future release but for the moment this particular issue is affecting me too much to leave the designer tools installed.

I've mentioned this in a previous post, but figured I'd repost it here in a more visible spot as a few people seem to have run into this same issue.

Thank you, thank you, THANK YOU!!! This has been bugging me for a couple of weeks now! I thought it was new, interesting behavior in VS2008 that I could not for the life of me find a way to fix.

It does kind of force you to think about your web.config. Try creating one from scratch with ASP.NET Ajax support, membership and all that new 3.5 crap. I bet no one can do it at once without an example, and save only once when done.

Web.config has become a mess, and it is my understanding that we need a new version of the CLR before they can move all that crap back to the machine level by default.

Anyway, thanks for the tip!

I noticed the same behavior - but found out what was causing it by happening upon the output window once, directly after it happened. I saw an error that actually pointed out the entity framework tools and thus, removed the wretched problem-causing add-on. Nonetheless, great job in identifying the issue.

Thanks for posting this - I thought my Visual Studio was acting all "special".

If you don't want to completely uninstall the Entity Designer tools, you can disable them temporarily by closing all instances of Visual Studio 2008 and then zipping up the following files in C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\

Microsoft.Data.Entity.Design.dll
Microsoft.Data.Entity.Design.EntityDesigner.dll
Microsoft.Data.Entity.Design.Package.dll

After backing up these files, delete them and restart Visual Studio 2008. You will get a message like the following that explains how to re-enable them when you want to play around with the designer:

---------------------------
Microsoft Visual Studio

Package Load Failure

Package 'Microsoft.Data.Entity.Design.Package.MicrosoftDataEntityDesignPackage, Microsoft.Data.Entity.Design.Package, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' has failed to load properly ( GUID = {8889E051-B7F9-4781-BB33-2A36A9BDB3A5} ). Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future? You may use 'devenv /resetskippkgs' to re-enable package loading.

Yes No

Another workaround is to mark an item in the solution explorer before saving, which is not part of the project to which the configuration file belongs. Like the solution top node or a file in an other project.
