.Net Core 2.2 "System.Resources.MissingManifestResourceException" when getting resource

I am using Telerik reporting in .Net Core 2.2. While trying to retrieve a .bmp image for the report, which is an embedded resource, I get the following error during Unit Testing:

System.Resources.MissingManifestResourceException
  HResult=0x80131532
  Message=Could not find any resources appropriate for the specified culture or the neutral culture.  Make sure "MyAssembly.TestReportGenerator.rptTestReportDocument.resources" was correctly embedded or linked into assembly "MyAssembly.TestReportGenerator" at compile time, or that all the satellite assemblies required are loadable and fully signed.
  Source=System.Private.CoreLib
