Problem with bulk operation

[Prutenskiy]

I have app witch configured as net472;netcoreapp3.1
I use Npgsql 4.*(try any vertions) for work with DB
INSERT\UPDATE worked fine, but when I try use bulk operation then on start app under net472 have this exception
"Void Npgsql.Bulk.NpgsqlBulkUploader..ctor(Microsoft.EntityFrameworkCore.DbContext)".

For bulk operation I try like this:

using (var ctx = new MyContext(NpgsqlDbContextOptionsExtensions.UseNpgsql(new DbContextOptionsBuilder(), _connectionStr).Options))
{
var d = new List();

        var uploader = new NpgsqlBulkUploader(ctx);
        uploader.Insert(d, Npgsql.Bulk.InsertConflictAction.Update<UserByRole>(........));
    }

Call stack:
at PGTestCommand.Test.Run() in C:...\Program.cs:line 45
at PGTestCommand.Program.Main(String[] args) in C:...\Program.cs:line 13

Exception Message:
Method not finde: "Void Npgsql.Bulk.NpgsqlBulkUploader..ctor(Microsoft.EntityFrameworkCore.DbContext)".

This problem only when start app under NET472. Same code under core work fine.

Have any some advise?

P.S. I download master, build project (only build Npgsql.Bulk), connect Npgsql.Bulk.dll to my test app and run. Evrething work in both mode(core and net). Maybe some problem in nuget packages?
