Hi Mohamed, 

Thanks for using Syncfusion product. 

The reported issue occurs when you try to refer the lower framework version(16.4400.0.52) assemblies in higher framework version(16.4460.0.52). You can resolve this issue by following any one step,   
Suggestion 1: 
Please remove the version and key tokens for all Syncfusion assemblies from your project. Please refer to the following code example. 
Code snippet        
<Reference Include="Syncfusion.SfListView.WinForms, Version=16.4460.0.52, Culture=neutral, PublicKeyToken= 3d67ed1f87d44c89, processorArchitecture=MSIL"> 
<--</Change the above code like as below for all Syncfusion assemblies>-->               
<Reference Include="Syncfusion.SfListView.WinForms ">  
Suggestion 2:           
  • Select all the Syncfusion assemblies from project reference and open the property window (Alt + Enter) for selected assemblies.
  • Change the specific version as false using property window for all Syncfusion assemblies.
  • Now, clean and rebuild your project.

Please get back to us if you need any further assistance on this.
