Question

In visual studio, I have an asp.net 3.5 project that is using MS Enterprise Library 4.0 application blocks.

When I have my web config file open, my Error list fills up with 99 messages with things like

Could not find schema information for the element 'dataConfiguration'.   Could not find schema information for the attribute 'defaultDatabase'.   Could not find schema information for the element 'loggingConfiguration'.    Could not find schema information for the attribute 'tracingEnabled'.    Could not find schema information for the attribute 'defaultCategory'.   

If I close the Web.config file they go away (but they come back as soon as I need to open the file again).

After doing some looking, I found that this is becauase there is an XSD or schema file missing that Visual Studio needs in order to properly ‘understand’ the schema that is in the web.config file and provide intellisense for it.

Does anyone know how to either supply VS with the appropriate schema information, or to turn off these messages?

@Franci – Thanks for the info, I have tried that tool as well as the MMC snap in (they tend to blow up the formatting in the Web.config) but they still do not resolve the irritating warnings I receive. Thanks for trying.

I configured the app.config with the tool for EntLib configuration and set up my LoggingConfiguration block. Then I copied this into the DotNetConfig.xsd. Of course, it does not cover all attributes, only the ones I added but it does not display those annoying info messages anymore.
