Alternative to use ExecuteTransactionRequest?

[priyanksster]

I am using version 1.0.25 of XRM.Tools.CRMWebAPI with Durable Function using .Net Core 3.1 . Just wondering, does the CRMWebAPI offer any alternative to using ExecuteMultipleRequest or ExecuteTransactionRequest of [Microsoft.Xrm.Sdk.Messages] . My requirement is to create/Update multiple entity records in one transaction so that if one fails , they all will be rolled over. For example.
Create 1 record in Entity A.
Create 2 records in Related Entity B
Update record in Entity C

If I recall correctly Task Create(string entityCollection, object[] datalist) does all work in a changeset

Hi @davidyack Thanks for your response but Task Create() is used for creating records for a particular entity. How can I use it to create records for multiple related entities?
