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

Simple  In Visual Studio Report designer 1  Open the report in design mode and delete the dataset from the RDLC File 2  Open solution Explorer and delete the actual  corrupted  XSD file 3  Add the dataset back to the RDLC file  4  The above procedure will create the new XSD file  5  More detailed is below      In Visual Studio  Open your RDLC file Report in Design mode  Click on the report and then Select View and then Report Data from the top line menu  Select Datasets and then Right Click and delete the dataset from the report  Next Open Solution Explorer  if it is not already open in your Visual Studio  Locate the XSD file  It should be the same name as the dataset you just deleted from the report   Now go back and right click again on the report data Datasets  and select Add Dataset   This will create a new XSD file and write the dataset properties to the report  Now your error message will be gone and any missing data will now appear in your reports

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

I found that there was a syntax error in the related module and it wasn t compiling - the compiler didn t tell me that though  Just gave me the error regarding the app config stuff  VS2010  Once I had fixed the syntax error  all was good

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
