[Solved] AsTransient() is missing for DateTime property

[Markus]

In my model a have a few transient properties which I can mark as follows

configuration.HasProperty( x => x.CalculatedProp).AsTransient();

But if property is of type DateTime it is not possible, because DateTimePropertyConfiguration does not have a function AsTransient().

How could I define a DateTime property as transient?
Is it possible to ignore properties which are not explicitly mapped or automatically mark them as transient?

Hello Markus,

 It is possible to achieve that using the .MapType() method. Whenever you use the MapType method without specifying a lambda expression this would instruct our metadata reader that all properties in that types will be default mapped if no explicit mapping is specified. 
If you however use a method like this:

productConfiguration.MapType(p => new
           {
               ProductId = p.Id,
               ProductName = p.Name,
               Discontinued = p.Discontinued,
               CategoryId = p.CategoryId
           }).ToTable("Products");

Only the Id,Name,Discontinued and CategoryId properties will receive default mapping unless other is not specified. All properties that are not mentioned in this lambda expression and do not have an explicit mapping provided with the HasProperty method will be regarded as transient.
The last possibility is to use this method with an empty lambda like this:

productConfiguration.MapType(x => new { }).ToTable("Product");

This would mean that no properties will receive default mapping and all will be considered to be transient unless explicit mapping is provided via the HasPropertyMethod.
I hope this was helpful to you. All the best,

Can I use the default mapping, and still specify a DateTime as Transient?

Hi Trevor,

 With the latest release of OpenAccess it is possible to specify .AsTransient() on properties of type DateTime.

We have version 2013.1.219.3 and I am unable to specify AsTransient() on any DateTime properties. If I add the AsTransient() to my configuration, it says "Cannot resolve symbol 'AsTransient".

It does, however, let me specify other types as Transient.

Is there something else I'm missing here?

Hello Trevor,

 The version you are using is not our latest internal build. You should be able to see the internal build under your downloads if you have downloaded the Q1 release from 2013 through our site.

All the best,
