Once your Azure Cosmos DB container is properly set up, using vector search via EF is a simple matter of adding a vector property and configuring it:c# Копирај public class Blog { ... public float[] Vector { get; set; } } public class BloggingContext { ... protected ...
MLContext is the starting point for all ML.NET operations. TheMLContextis used for all aspects of creating and consuming an ML.NET model. It is similar conceptually toDbContextin Entity Framework. varmlContext=newMLContext(); Once you have an instance of anMLContext, you can load and trans...
Entity Framework Extensions is nothing but a library that dramatically progresses the Entity Framework performances by using bulk and batch operations.
