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

UPDATE Sept 2015 This answer continues to get upvotes  so I m going to leave it here since it seems to be helpful to some people  but please check out the other answers from  reexmonkey and  Pressacco first  They may provide better results   ORIGINAL ANSWER Give this a shot    In Visual Studio  open your app config or web config file    Go to the  XML  menu and select  Create Schema   This action should create a new file called  app xsd  or  web xsd   Save that file to your disk  Go back to your app config or web config and in the edit window  right click and select properties  From there  make sure the xsd you just generated is referenced in the Schemas property  If it s not there then add it     That should cause those messages to disappear   I saved my web xsd in the root of my web folder  which might not be the best place for it  but just for demonstration purposes  and my Schemas property looks like this       C  Program Files  x86  Microsoft   Visual Studio   10 0 xml Schemas DotNetConfig xsd   Web xsd

Most of what I write has already been covered by Pressacco  but this is specific to SpecFlow   I was getting this message for the  lt specFlow gt  element and therefore I added a specflow xsd file to the solution this answer  with some modifications to allow for the  lt plugins gt  element     Thereafter I  like Pressacco   right clicked within the file buffer of app config and selected properties  and within Schemas  I added  specflow xsd  to the end   The entirety of Schemas now reads    C  Program Files  x86  Microsoft Visual Studio 12 0 xml Schemas 1033 DotNetConfig xsd   C  Program Files  x86  Microsoft Visual Studio 12 0 xml Schemas EntityFrameworkConfig 6 1 0 xsd   C  Program Files  x86  Microsoft Visual Studio 12 0 xml Schemas RazorCustomSchema xsd   specflow xsd

I had this in VS 2012 where the  Section name  had been changed in a project  and I fixed it by deleting  app config  in the project  then right-clicking on the project in the  Solution Explorer   selecting  Properties   then  Settings   then making a change to one of the settings  saving  and re-building  This created a new app config with the correct information
