Hi Olayinka,

From the given details, we have found that the two (Syncfusion.DocIO.Wpf and Syncfusion.DocIO.ClientProfile) NuGet packages are referred in your WPF platform application.

For your reference, we have prepared the sample to refer the NuGet packages properly in the application and it can be downloaded from the below attachment.

To resolve the reported issue, we suggest you to install “Syncfusion.DocIO.ClientProfile” NuGet package if you are using the target framework as “.NET Framework 3.5 or 4.0 Client Profile” in your application. Otherwise, install “Syncfusion.DocIO.Wpf” NuGet package based on the platform.

It is a winform application. I used sfrichtextboxadv.wpf using element host. So the nuget packages were installed by automatically by themselves. 

How can this be resolved?

Hi Olayinka,

To avoid this assembly conflict in your project, we request you to use the extern alias feature in .NET which allows you to give referenced Nugets an alias and use the alias for the respective elements.

The Alias can be set through that Aliases property in the property window for any referenced Nuget libraries as shown below.

And created a sample to demonstrate the same, which can be downloaded from the below location
https://www.syncfusion.com/downloads/support/forum/175476/ze/SFRICH~1-1774618070

Please let us know if you have any other questions.
