Setup and compile on VS 2013 and JS1 sample code base (

I'm getting these many errors when trying to compile the latests sample Javascript JS1 project from E:\Users\Public\Documents\Syncfusion\JavaScript\ with VS2013.  I'm running Windows 7x64, VS 2013 and the latest JS1 sample/demo app downloaded from your website.

Error 19 Assembly 'Syncfusion.EJ.ReportDesigner, Version=16.3451.0.29, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89' uses 'Syncfusion.EJ.ReportViewer, Version=16.3451.0.29, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89' which has a higher version than referenced assembly 'Syncfusion.EJ.ReportViewer, Version=13.1451.0.30, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89' E:\Users\Public\Documents\Syncfusion\JavaScript\\ejservices\packages\Syncfusion.Web.ReportDesigner.\libet451\Syncfusion.EJ.ReportDesigner.dll ejservices_2013


Error 21 The type or namespace name 'PMML' does not exist in the namespace 'Syncfusion' (are you missing an assembly reference?)

E:\Users\Public\Documents\Syncfusion\JavaScript\\ejservices\Models\PredictiveModel.cs 8 18 ejservices_2013

There is a total of 97 errors...

In case of PMML it is there....  could it be that some of these base packages are compiled with a later version of .net?

Thanks for you help

Hi David, 

Greetings from Syncfusion, 

We were able to reproduce the issue “Assembly Conflict” and we confirm this as a bug and logged a defect report. The fix will be available in our upcoming Service Pack release. 

Please follow the workaround steps to resolve this issue as of now.

C:\Program Files (x86)\Syncfusion\Essential Studio\\Utilities\Assembly Manager\AssemblyManagerWindows.exe 
  1. Select the Remove Version Refer the screenshot below.
  1. Click Perform Action.
  1. Once Assembly Manager completed, you can clean and rebuild the ejservice application.

Hi David, 

Please follow the steps to install the v16.3.0.21 assemblies alone to GAC.

We will resolve this issue in our upcoming service pack release.
