Just trying an upgrade to V5 beta and have this message on compile:

Error 27 'Xtensive.Orm.Session' does not contain a definition for 'DisableValidation' and no extension method 'DisableValidation' accepting a first argument of type 'Xtensive.Orm.Session' could be found (are you missing a using directive or an assembly reference?)

I disable data validation when loading data on startup. I s this going to be put back in on subsequent releases.

One Answer:

Hello Tony,

we reworked validation framework in DO5.

In particular DisableValidation() method is no longer required because validation happens only in two cases:

  • Just before transaction is committed
  • Explicit Session.Validate() call

This means that your code don't need to call DisableValidation to achieve old behavior.
