I have a WCF project which reference from 2 projects.
- A library project (A).
- Data Contract Library (B)- A separate project.
This project a reference from FaceSDK.NET third party library. I have used this FaceSDK.NET dll file in another project. But it required to insert in to App.config
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
<supportedRuntime version="v2.0.50727"></supportedRuntime>
</startup>
I want to use the functionality in library project in my WCF project. When I build the project, it build fine. But when it run on the WCF test client, it gives an error as below.
Server Error in '/' Application.

Some has suggested that this is due to target platform incompatibility. I have tried to keep it to a single platform. I also tried to add a App.confing file, But no use. Help is greatly appreciated.
In this post, has a similar issue, But this is WCF related.
Edit:
I would add some more information. This project A uses EmguCV wrapper. When I added the OpenCV files (these are 500MB) explicitly to the WCF service's bin it gives the above error. When I removed these files and then put only the project reference the error is bit different.
