MongoDB Entity Framework Provider Demo

What

A simplistic application that uses the official MongoDB Entity Framework Core Provider.

NuGet: NuGet Gallery | MongoDB.EntityFrameworkCore 7.0.0-preview.1

Repo: mongodb/mongo-efcore-provider: MongoDB Entity Framework Core Provider (github.com)

Docs: MongoDB Entity Framework Core Provider — Entity Framework

Why

Entity Framework has long been available to attempt to smooth unify and unify the tasks of storing .NET entities in a backing relational database.

The MongoDB provider for EF is an effort to give similar EF user experience, but with a document database backing.

Note: The current provider is in preview status.

So... this will age nicely :-)

Notes

1. In the 8.0 GA release, both BsonElementAttribute() (MongoDB) and ColumnAttribute() (EF / Data Annotation) are respected. You can name the MongoDB side field and keep your POCO names as you wish.
2. Applying [BsonRepresentation(..)] to a POCO attribute throws.
3. Applying [BsonId] attribute to a field on a POCO works - you can choose which property will map to the MongoDB document's _id field.
4. Using the ModelBuilder to set property behavior such as conversion POCO <--> BSON, value generation etc demo updated, for specific properties.
