Problem with Assembly reference and Version


I have come to a bit of a bump while trying to Use any Syncfusion Control on my visual studio 2013.

 I get the following errors please help

Warning 3 The primary reference "Syncfusion.Shared.Web, Version=11.4451.0.26, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the assembly "Syncfusion.Shared.Base, Version=11.4451.0.26, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" which was built against the ".NETFramework,Version=v4.5.1" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.5". 

but I also have  .NET FRAMEWORK 4.5.1

Error 5 The type or namespace name 'Web' does not exist in the namespace 'Syncfusion' (are you missing an assembly reference?)  

 The type or namespace Syncfusion could not be found

Hi Bob,


Thanks for your interest in Syncfusion products.


This error occurred due to the mismatching of frame work version and Syncfusion assembly reference version. To change your frame work version we suggest you to change in project file that displays your frame work version. In this case we suspect that your application constructed using frame work version 4.5 and you are using Syncfusion assembly reference as 11.4451. For this we suggest you to change the version of the application frame work in project file to 4.5.1 or use assembly reference as 11.4450.


Please refer the following code snippet:








Kindly try the attached sample and let us know if this helps.
