+```

+### Remarks
+
+In situations where an instance of [Microsoft\.EntityFrameworkCore\.DbContextOptions](https://docs.microsoft.com/en-us/dotnet/api/Microsoft.EntityFrameworkCore.DbContextOptions 'Microsoft\.EntityFrameworkCore\.DbContextOptions') may or may not have been passed
+to the constructor, you can use [Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder\.IsConfigured](https://docs.microsoft.com/en-us/dotnet/api/Microsoft.EntityFrameworkCore.DbContextOptionsBuilder.IsConfigured 'Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder\.IsConfigured') to determine if
+the options have already been set, and skip some or all of the logic in
+[Microsoft\.EntityFrameworkCore\.DbContext\.OnConfiguring\(Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder\)](https://docs.microsoft.com/en-us/dotnet/api/Microsoft.EntityFrameworkCore.DbContext.OnConfiguring#Microsoft_EntityFrameworkCore_DbContext_OnConfiguring_Microsoft_EntityFrameworkCore_DbContextOptionsBuilder_ 'Microsoft\.EntityFrameworkCore\.DbContext\.OnConfiguring\(Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder\)').
