Hi,

I created my first Avalonia UI app in MVVM pattern and already installed EFCore 8.0.6 in the project. But failed to access the localdb.

My troubleshoot:

  1. Created a simple console project. No issue. See attached pic1.Image 3
  2. In Avalonia app, checked the localdb instance name, status. Verified EF is installed. Build OK, but connection failed. See attached pic2.Image 4
  3. Microsoft.EntityFrameworkCore., Microsoft.EntityFrameworkCore.SqlServer, Microsoft.EntityFrameworkCore.Tools are installed. Could anybody tell me how to fix it? Thanks.

    NVM. I am stupid. Server should be "(localdb)\TS9999", not "(localdb)\TS9999"
