Looks like that RadZen is not compatible with MariaDB. I tried the mySQL connector and it failed.
Indeed we have only tested with MySQL databases. I am not sure if the Entity Framework Core connector that Radzen uses supports MariaDB.
That's too bad. Probably leaves me out for now. I respect the fact that you all are working very hard to produce a high quality professional RAD tool.
We'll test with a local MariaDB installation and report our findings. Maybe it is something that we can easily fix.
