Hi,

The project "EFCore.Cassandra" is using "Microsoft.EntityFrameworkCore" version "3.1.4", therefore the version "5.0.1" cannot be included in your project.

Do you plan on updating this DB provider to support EF Core 5 in the near future?

[simpleidserver]

EF Core 5 will be supported in the next release (version 3.0.0), it will be published in February.

The project has been migrated to NET5.0. please refer to the branch "origin/release/3.0.0"
