Not respecting MetadataType? #585
Description
I am trying to implement defining attributes for a class in another class using MetadataType as per MSDN (https://msdn.microsoft.com/en-gb/library/ff664465(v=pandp.50).aspx). I'm using XF 2.3.4.247 in VS 2017 with PCL profile 259.
As far as I can tell this is supported in .NET Standard 1.6 and above, but I need 1.4 for UWP. It is not supported in PCL/XF out the box. I found a nuget package that implements this for PCL (https://github.com/ryanhorath/PortableDataAnnotations).
Based on MSDN it would be like this:
namespace a_sln
{
[MetadataType(typeof(fredmetadata))]
public class fred
{
public int id {get; set;}
public List<int> nums {get; set;}
}
[Table("tbl_fred")]
public class fredmetadata
{
[PrimaryKey]
public object id {get; set;}
[Ignore]
public object nums {get; set;}
}
}
When I call CreateTableAsync I would expect a table to be created called 'tbl_fred' with a PK of 'id' and no errors about not knowing what to do with collections. The above example doesn't work at all, it doesn't even see [Table].
The nearest I have got to working is this:
namespace a_sln
{
public partial class fred
{
public int id {get; set;}
public List<int> nums {get; set;}
}
[MetadataType(typeof(fredmetadata))]
[Table("tbl_fred")]
public partial class fred
{
internal class fredmetadata
{
[PrimaryKey]
public object id {get; set;}
[Ignore]
public object nums {get; set;}
}
}
}
This acts like it can see the [Table] attribute but not the property attributes. I've tried several variations on a common theme and the results are the same or VS (2017) complaining about duplicates.
I am assuming the nuget package is not at fault by virtue of the fact that the [Table] attribute is working, but I am happy to be corrected.
