I am having a problem mapping a complex type in LinqConnect for Metro. Version 4.4.383

On creating the db I get the following exception:

System.ArgumentException was unhandled by user code
HResult=-2147024809

My classes:

public class Complex

public string Prop1 { get; set; }

public class Class4

public Complex Complex { get; set; }
}

My mapping definition:

builder.ComplexType<Complex>().Property(c => c.Prop1).ServerDataType("String").NotNullable();

builder.Entity<Class4>().FullTableName(@"""Class4""").PrimaryKey(class4 => class4.Id);
builder.Entity<Class4>().Property(class4 => class4.Complex.Prop1).ColumnName("Prop1").ServerDataType("String").NotNullable();

Thank you for the report on this. We have reproduced this issue. We will investigate it and inform you about the results as soon as possible.

We have fixed this issue. We will inform you when the corresponding build of LinqConnect for Metro is available for download.
As a temporary workaround, you can disable ServerDataTypeConvention (only in case, when ServerDataType is correctly specified for all entity properties of your model). For example, use this code:

Code: Select all

private static MappingSource GetMappingSource(DataProvider provider) 
{
FluentMappingBuilder builder = new FluentMappingBuilder(provider);
#region Disabled conventions
builder.Conventions.Remove<ServerDataTypeConvention>();
#endregion
....
}
