  Update dependency for Forms Service API

Try to install following NuGet packages in a same project:

  • EPiServer.ContentDeliveryApi.Search
  • EPiServer.Forms.ServiceApi

The issue is that both has a dependency of another NuGet package (Microsoft.AspNet.OData) but to different versions. EPiServer.ContentDeliveryApi.Search needs Microsoft.AspNet.OData between 6.0.0 - 7.0.0, whereas EPiServer.Forms.ServiceApi needs Microsoft.AspNet.OData between 5.6.0 - 6.0.0, making it almost impossible to install both NuGet packages in same project.

EPiServer.Forms.ServiceApi 4.0.0; (Or a related package);
