Unable to create a 'DbContext' of type 'ApplicationDbContext'.

[alpemreelmas]

Hello folks, I've been trying to switch mssql to postgresql for azure which is my subscription that supports it. I've received this error and I couldn't find any information is it related this template or general ? I also couldn't find any possible solutions.

Unable to create a 'DbContext' of type 'ApplicationDbContext'. The exception 'The type initializer for 'Npgsql.EntityFrameworkCore.PostgreSQL.Storage.Internal.Mappin
g.NpgsqlBigIntegerTypeMapping' threw an exception.' was thrown while attempting to create an instance. For the different patterns supported at design time, see https

If any of you know the solution I'd be grateful to learn
Thanks
