Load multiple levels of related entities: using (varctx=new SchoolDBEntities()) {varstud1=ctx.Students.Include("Standard.Teachers") .Where(s=>s.StudentName=="Student1") .FirstOrDefault<Student>(); } using (varct
Note that Include is an extension method in the System.Data.Entity namespace so make sure you are using that namespace. Eagerly loading multiple levels It is also possible to eagerly load multiple levels of related entities. The queries below show examples of how to do this for both collectio...
I can’t talk about using multiple levels of Include without adding a reminder that the more relationships you attempt to eager load with Include, the more complex and degraded your SQL query could become. I always highly recommend profiling the SQL generated by Entity Framework (EF). In fact...
EF Core 6.0 Release Candidate 1 was released to NuGet a few weeks ago. This release is the first of two “go live” release candidates that are supported in production. EF Core 6.0 RC1 runs on Release Candidate 1 for .NET 6.0, which also has a “go live” license. ...

Xu et al.23 used BERT as an encoder and integrated the representation of the entire future and past sentences into each cell’s sentence representation within the BiLSTM framework through a global context mechanism, improving entity recognition performance. Large language models (LLMs) leverage vast...
The ER model follows McCarthy's “REA” framework proposed in 1982, which shows three categories of entities (rectangles)—resources on the left, events in the middle, and agents on the right. The lines connecting the entities indicate the type of relationship between the entities, including ...
at Microsoft.EntityFrameworkCore.ChangeTracking.Internal.InternalEntityEntry.PrepareToSave() This is because a single instance of the Address entity type (with the same hidden key value) is being used for three different entity instances. On the other hand, sharing the same instance between complex...
These datasets were chosen because they are widely used for EA and most of them have features such as entity semantics and attribute semantics that can be used to validate our proposed framework. The statistical details of dataset are shown in Table 1. We preprocessed the dataset before the ...
more attributes to be adiscriminatorso the framework can automatically determine which rows map to which entity objects, and manage entity object storage. You would omit columns that do not apply to the entity object you are defining; however, each entity object must always include the primary ...
