Full message
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - Undefined error: 0)
I've been having this problem for a while no. Have checked similar posts on same error but none seem so to have (provider: TCP Provider, error: 0 - Undefined error: 0). I couldn't find any that matched undefined error: 0, that last part always referred to a specific problem on other posts.
I am working on macOs Catalina 10.15.6 using MS Sql Server 2017 on a docker container.
On terminal, I would create migrations as follows
dotnet ef migrations add myMigrations
The issue happens when I do, after migrations created successfully
dotnet ef database update -p ../MyApp.DataAccess
The output is as follows
Build started...
Build succeeded.
