The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition' which cannot be upgraded.

Hi All,
I realised that getting sparkline in Visual studio 2008 is not so easy. So I downloaded report builder 3.0 and run the table with sparkline. I was happy that I was able to run it.
But when I tried to save this report and access it through visual studio 2008 it would give me the below error.

"The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition' which cannot be upgraded."

To resolve this issue..I followed the below steps
1. Open another running report xml code in visual studio and copy the first 2 lines ..I had the below


<?xml version="1.0" encoding="utf-8"?>
<Report xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner" xmlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition">

I later got the error message as stated below

"Deserialization failed: The element 'Report' in namespace 'http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition' has invalid child element 'ReportSections' in namespace 'http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition'. List of possible elements expected: 'Description, Author, AutoRefresh, DataSources, DataSets, Body, ReportParameters, Code, Width, Page, EmbeddedImages, Language, CodeModules, Classes, CustomProperties, Variables, DeferVariableEvaluation, ConsumeContainerWhitespace, DataTransform, DataSchema, DataElementName, DataElementStyle' in namespace 'http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition' as well as any element in namespace '##other'. Line 4, position 4."

For this deleted the lines that contained 

<ReportSections>

    <ReportSection>

   and </ReportSections>

    </ReportSection>

Bingo!

I was able to open the reports made in report builder 3.0 in Visual studio 2008
