Completely rewritten DBreeze Vector Layer with Similarity Search and Clustering. Now it is based on KMeans++ Centroid Propagated Graph. Fast speed of inserts and search. This functionality is available in DBreeze for .NET Framework 4.72>, .NET6> .NetCoreApp3.1> .NetStandard2.1>
Vector layer is in intensive beta testing.

.NET 6 support

On the early stage helps the programmers to put a modifying table into the transaction.SynchronizeTables statement.

Can be switched off by:
