DbTransaction.Dispose Method (System.Data.Common) | Microsoft Learn[^]:

Dispose should rollback the transaction. However, the behavior of Dispose is provider specific, and should not replace calling Rollback.

OpenSilver is a modern, plugin-free, open-source reimplementation of Silverlight. It uses WebAssembly to bring back the power of C#, XAML, and .NET to client-side Web development.
