How to resolve Could not find schema information for the element attribute xxx

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

Have you tried copying the schema file to the XML Schema Caching folder for VS? You can find the location of that folder by looking at VS Tools/Options/Test Editor/XML/Miscellaneous. Unfortunately, i don't know where's the schema file for the MS Enterprise Library 4.0.

Update: After installing MS Enterprise Library, it seems there's no .xsd file. However, there's a tool for editing the configuration - EntLibConfig.exe, which you can use to edit the configuration files. Also, if you add the proper config sections to your config file, VS should be able to parse the config file properly. (EntLibConfig will add these for you, or you can add them yourself). Here's an example for the loggingConfiguration section:

<configSections>
    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</configSections>

You also need to add a reference to the appropriate assembly in your project.

Navigate to this   NLog xsd files  Download the appropriate xsd for your project and save it along the NLog config  The first one did the trick for me

An XSD is included with EntLib 5  and is installed in the Visual Studio schema directory   In my case  it could be found at   quot C  Program Files  x86  Microsoft Visual Studio 10 0 Xml Schemas EnterpriseLibrary Configuration xsd quot  CONTEXT  Visual Studio 2010 Enterprise Library 5  STEPS TO REMOVE THE WARNINGS  open app config in your Visual Studio project right click in the XML Document editor  select  quot Properties quot  add the fully qualified path to the  quot EnterpriseLibrary Configuration xsd quot   ASIDE It is worth repeating that these  quot Error List quot   quot Messages quot    quot Could not find schema information for the element quot   are only visible when you open the app config file   If you  quot Close All Documents quot  and compile    no messages will be reported

What fixed the  Could not find schema information for the element      for me was   Opening my app config  Right-clicking in the editor window and selecting Properties  In the properties box  there is a row called Schemas  I clicked that row and selected the browse     box that appears in the row  I simply checked the use box for all the rows that had my project somewhere in them  and also for the current version of  Net I was using   For instance  DotNetConfig30 xsd    After that everything went to working fine   How those schema rows with my project got unchecked I m not sure  but when I made sure they were checked  I was back in business

I ve created a new scheme based on my current app config to get the messages to disappear  I just used the button in Visual Studio that says  Create Schema  and an xsd schema was created for me   Save the schema in an apropriate place and see the  Properties  tab of the app config file where there is a property named Schemas  If you click the change button there you can select to use both the original dotnetconfig schema and your own newly created one

An XSD is included with EntLib 5  and is installed in the Visual Studio schema directory   In my case  it could be found at   quot C  Program Files  x86  Microsoft Visual Studio 10 0 Xml Schemas EnterpriseLibrary Configuration xsd quot  CONTEXT  Visual Studio 2010 Enterprise Library 5  STEPS TO REMOVE THE WARNINGS  open app config in your Visual Studio project right click in the XML Document editor  select  quot Properties quot  add the fully qualified path to the  quot EnterpriseLibrary Configuration xsd quot   ASIDE It is worth repeating that these  quot Error List quot   quot Messages quot    quot Could not find schema information for the element quot   are only visible when you open the app config file   If you  quot Close All Documents quot  and compile    no messages will be reported

Have you tried copying the schema file to the XML Schema Caching folder for VS? You can find the location of that folder by looking at VS Tools/Options/Test Editor/XML/Miscellaneous. Unfortunately, i don't know where's the schema file for the MS Enterprise Library 4.0.

Update: After installing MS Enterprise Library, it seems there's no .xsd file. However, there's a tool for editing the configuration - EntLibConfig.exe, which you can use to edit the configuration files. Also, if you add the proper config sections to your config file, VS should be able to parse the config file properly. (EntLibConfig will add these for you, or you can add them yourself). Here's an example for the loggingConfiguration section:

<configSections>
    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</configSections>

You also need to add a reference to the appropriate assembly in your project.

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

I ve created a new scheme based on my current app config to get the messages to disappear  I just used the button in Visual Studio that says  Create Schema  and an xsd schema was created for me   Save the schema in an apropriate place and see the  Properties  tab of the app config file where there is a property named Schemas  If you click the change button there you can select to use both the original dotnetconfig schema and your own newly created one

What fixed the  Could not find schema information for the element      for me was   Opening my app config  Right-clicking in the editor window and selecting Properties  In the properties box  there is a row called Schemas  I clicked that row and selected the browse     box that appears in the row  I simply checked the use box for all the rows that had my project somewhere in them  and also for the current version of  Net I was using   For instance  DotNetConfig30 xsd    After that everything went to working fine   How those schema rows with my project got unchecked I m not sure  but when I made sure they were checked  I was back in business
