BC30560: 'ColorPicker' is ambiguous in the namespace 'Syncfusion.JavaScript.Web'.

[Dario]

I am unable to start simple ColorPicker control
What I have done so far:
1. Add reference Syncfusion.EJ.Web to the project in VS 2013
2. Update web.config
<add assembly="Syncfusion.EJ.Web, Version=12.4451.0.24, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" />
3. Drag-and-Drop ColorPicker control to test_S.ascx
4. Add <%@ Register Assembly="Syncfusion.EJ.Web, Version=12.4451.0.24, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" Namespace="Syncfusion.JavaScript.Web" TagPrefix="ej" %> at the top of test_S.ascx
5. I am using Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.18408

I am getting:

Hi Dario,

Thanks for using Syncfusion products.

The reported issue has occurred due to mismatching of DLL version in your sample. If you are using 12.4.0.24 and if the frame wok version is 4.0, then the DLL version should be 12.4400.0.24. Please check the ‘bin’ folder and refer the following table for DLL reference.

.Net Frame Work Version	DLL Reference
4.0	12.4400.0.24
4.5	12.4450.0.24
4.5.1	12.4451.0.24

Please follow the steps below:

1. Open the Syncfusion Essential Studio and click on Explore sample.

2. Click on samples and open web folder, you can get the bin folder inside.

3. Check the version of DLL inside the bin folder.

DLL version should match the framework version you have used. And also, please check the web.config file in your sample.

All the assemblies referred inside the web.config file should match your .NET framework version.

When the assemblies are referred from GAC reference, follow the provided steps.

1. Open Solution Explorer in the application, click on References and get the Syncfusion.EJ and Syncfusion.EJ.Web assembly references.

2. View the properties by right-clicking the Syncfusion.EJ.Web, inside references.

3. Check the version of the assembly in the Properties tab.

We have prepared the sample with basic Colorpicker component and it can be downloaded in the following location.
