The significance of the date 2009-01-01

-
I discovered this feature when working on D365FO for Retail. Store transactions were synced back into D365 with a datetime field which had the value 1753-01-01 (the mindate of the datatype on SQL server).

The mindate in D365 is 1900-01-01 which is greater than 1753-01-01 so you might expect that D365 would return 1900-01-01 instead of 1753-01-01. However that is not the case. 

When the transaction was read the date returned is 2009-01-01 instead of the true value 1753-01-01. 

This was discovered when looking into problems with the field RetailTransactionTable.ReceiptDateRequested  which looks to be related to KB 4058850

How to disable auto enabled flight key using KillSwitch

Microsoft is introducing new functionality into Dynamics 365 for Finance and Operations with flight keys in every other new release. For this they use  Flight  classes so that the changes are automatically applied and can be reversed.  Example of a flight class that control the functionality of a new set of functionality.  When a flight key that enable functionality can be found in the flight key table  SysFlighting To disable the functionality don't delete or change the enabled flag on the flight record, instead insert a KillSwitch  record. The KillSwitch record will ensure that the flighed functionality will stay disabled as long as it exist in the flight table.  In an environment that Microsoft maintain can raise a support ticket in LCS to disable specific flight keys.  SQL statement for insert the KillSwitch record.  DECLARE @flightName NVARCHAR(100) = 'WHSWorkCancelForcedFlight_KillSwitch' IF NOT EXISTS (SELECT TOP 1 1 FROM SysFlighting WHERE flightName = @flightName

Feature management is an alternative to configuration keys for releasing and introduce a new features into D365FO.  MS is still releasing updates around the framework but the existing state as per 10.0.9 provide all we need to get started with releasing functionality that is controlled by the feature management framework.  The key to the feature framework is the feature class, in my example below see the class  pekTestingFeature. It is used as a descriptor for the feature and the flag to indicate if the feature is enabled or not. Once the class is created and compiled, users can navigate to Feature management  under System administration  and enabled/disable the feature. It is possible to make a feature enabled by default or disable the possibility to disable the feature. If the feature doesn't automatically appear, run the Check for updates button.   The feature class can be applied to menu items and menus. If enabled the menu item or menu will be visible to the

If you are working with the new unified development environments and CICD pipelines described here .  You might find the fact that we have to update the pipeline with the platform and application version annoying.  A quick way to get around this if you are using azure hosted agent pipeline as per this repo is to pull the number from the package.config and using it in the create deployable package task as per the two example tasks below.  The first powershell task will pull the version from the nuget files and save it to variable that can be reused in later tasks within the job.
