DllNotFoundException: Could not find LiteCore.dll! Nothing is going to work!

Mobile Couchbase Lite
1

Here’s how I produced the error.

  • Create a class library
  • Add a reference to CouchBaseLite
  • Create a WPF application
  • Add a reference to the class library in the WPF application
  • Run the application

The LiteCore.dll file in the bin\debug\x64 and bin\debug\x86 folders in the class library are not copied to the WPF application

Here’s the full error message.

@QsWZJuPYAh2Wh7dZ You will also need to add the Couchbase Lite Support nuget package depends on what platform you are working with. Here is the documentation FYI: Installing Couchbase Lite on .Net | Couchbase Docs

I read the documentation and I’m a bit confused.

Does the support package provide the LiteCore.dll file? If so, does the support package only need to only be installed in the project using Couchbase Lite or also in all projects referencing the project using Couchbase Lite? Thanks.
