Entity Framework Core - setting the decimal precision and scale to all decimal properties [duplicate]

Answer 1

You got close. Here's the code.

foreach (var property in modelBuilder.Model.GetEntityTypes()
    .SelectMany(t => t.GetProperties())
    .Where(p => p.ClrType == typeof(decimal) || p.ClrType == typeof(decimal?)))
{
    // EF Core 1 & 2
    property.Relational().ColumnType = "decimal(18, 6)";

    // EF Core 3
    //property.SetColumnType("decimal(18, 6)");

    // EF Core 5
    //property.SetPrecision(18);
    //property.SetScale(6);
}
