In my Blazor web app on .NET 9, when I'm doing the Update-Database for my MySql database v8.4.3, I get this error:
fail: Microsoft.EntityFrameworkCore.Database.Connection[20004]An error occurred using the connection to database '' on server ''
Does the message mean that the IP address and database name are missing? Because the error message does not indicate the database name and IP address.
Here are the packages I've installed:
<ItemGroup><PackageReference Include="Microsoft.EntityFrameworkCore" Version="9.0.0" /><PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="9.0.0"><PrivateAssets>all</PrivateAssets><IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets></PackageReference><PackageReference Include="Microsoft.EntityFrameworkCore.Relational" Version="9.0.0" /><PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="9.0.0" /><PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="8.0.2" /></ItemGroup>This is the appsettings.json file:
"ConnectionStrings": {"DefaultConnection": "Server=x.x.x.x;Port=3306;Database=DB_Cours;User=UserCours;Password=12345678";Trusted_Connection=True;MultipleActiveResultSets=true},
