This .NETFramework nuget package was updated today and now breaks.

The stack trace is:

at Twilio.Http.Request.buildUri()
at Twilio.Http.Request.ConstructUrl()
at Twilio.Clients.TwilioRestClient.Request(Request request)
at Twilio.Rest.Api.V2010.Account.MessageResource.Create(CreateMessageOptions options, ITwilioRestClient client)

The new line has: string[] strArray = uriBuilder.Host.Split('.', StringSplitOptions.None);

Same issue with 5.46.1. Rolling back to 5.46.0 is fine. Happens with a simple call to MessageResource.Create.

Same issue with Microsoft .NET applications. Twilio.6.3.0 - Framework 4.8 or later Twilio.6.2.5 - Framework 4.7.2

@Paulwills No, they fixed it in 5.55.0. Update your packages with reinstall, clean solution, then build.

I’m having this issue too and seeing the change in the decompiled code. This is probably due to your build server having a greater version of .NET than the ostensible target (4.5.1) so the wrong overload is being called.

This is what it is now (5.46.1):

This is what is was in 5.46.0:
