Hi Collins,

We have analyzed your query, when you open project in Visual studio 2010, it automatically refers the assembly version of 4.5. So you have to remove all assembly version from the GAC and install version 4.0 alone. Please do the following steps,

1.Open Dashboard.

2.Select Utilities>Assembly Management>Launch.

3.Syncfusion Assembly Manager window will open

4.Choose  Remove  version>Select all version>Perform action.

5.Once action completed Choose Install version>Select only 4.0>Perform action.

Once the assemblies installed open dashboard and check Blend Styling Demo Designer Page. Error message will be not shown.

Please let us know if you have any queries.
