In one of my project i have used reportviewer control to display reports on web pages and at time of uploading on Azure I have followed the steps mentioned [here](http://msdn.microsoft.com/en-us/library/windowsazure/gg430128.aspx) 

After uploading when i runs that report web page then it's giving me below error

> 
> 
> ```
> An error occurred during local report processing.
> The definition of the report 'Reports\Report1.rdlc' is invalid.
> An unexpected error occurred in Report Processing.
> Could not load file or assembly 'Microsoft.ReportViewer.ProcessingObjectModel, >    
> Version=10.0.0.0,
> Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its

>

>

What should be cause of this?

**Update**:

I have added following 2 dlls as shown in below snap
Microsoft.ReportViewer.Common.dll (10.0)  

Microsoft.ReportViewer.WebForms.dll (10.0)
