Bson Annotation not working with MongoDB Entity Framework

Hi, @Rajesh_Chanchalfas,

Welcome to the MongoDB Community Forums. I understand that you have encountered an error Property '<<Class.Property>>' is annotated with unsupported attribute. We have implemented support for BSON attributes in our EFCore Provider that map to equivalent EFCore semantics. Unfortunately EFCore does not support all semantics provided by the .NET/C# Driver. One of those is [BsonIgnoreIfNull]. The current release (8.0.3) supports all BSON attributes noted in “first round” and “second round” of EF-96. EF-96 also contains a list of BSON attributes that are not supported by EFCore.

Sincerely,
James
