Trouble with connecting a simple Blazor Server app to a local MySQL database RRS feed

  • Question

  • I have a very simple Blazor Server application running successfully on a PC. Everything works as expected except I can't connect to the MySQL database on the same server. I've tried "localhost" and the IP address of the PC to connect but it fails. I'm using some C# code that I use in my WPF applications that connects to the same database perfectly.

    I'm just not sure what I'm missing to make the connection work. Any ideas? Thanks!

  • It would be wonderful to have the exact error message. Also consider using Fiddler to monitor what's going on while attempting to connection or use SSMS Activity Monitor which may assist.

    Please remember to mark the replies as answers if they help and unmarked them if they provide no help, this will help others who are looking for solutions to the same or similar problem. Contact via my Twitter (Karen Payne) or Facebook (Karen Payne) via my MSDN profile but will not answer coding question on either.

    NuGet BaseConnectionLibrary for database connections.

  • When it tries to connect I get: Exception thrown: 'System.TypeInitializationException' in MySql.Data.dll

    I've installed Fiddler and ran it but I don't see anything about MySQL in there unless I'm missing it.

    Everything else with the Blazor program works great, I just can't get it to connect.
