Azure Search .Net SDK throws InvalidOperationException with SerializationBinder - azure

Question

I'm playing around with Azure Search .NET SDK on .NET Core (specifically, cloning the sample from Github - https://github.com/Azure-Samples/search-dotnet-getting-started)
When entering any operation with index (create, delete...) it throws an exception with SerializationBinder from Newtonsoft.Json like this
System.InvalidOperationException: Cannot get SerializationBinder because an ISerializationBinder was previously set. at Newtonsoft.Json.JsonSerializer.get_Binder()
--- End of inner exception stack trace ---

I believe that's something wrong with the SDK itself as I cloned the public github repo. Is that right?

Answer 1

This was caused by a known compatibility issue that many Azure SDKs have with JSON.NET version 10. The details are here and here.
This was fixed in Microsoft.Azure.Search versions 3.0.5 and 4.0.2-preview.

Answer 2

I also can repro the issue you mentioned when I try to execute DeleteHotelsIndexIfExists function if the index is not existed.
Other actions such as Creating index,Uploading documents there are working correctly on my side.
After some investigation, I found that Microsoft.Extensions.Configuration.Json is preview version.
Please have a try to update to lastest stable 1.1.2 version. Then it works correctly on my side.
