Unzip a Stream in Dynamics 365 FnO

Since Microsoft Dynamics 365 for Finance & Operations is a cloud-based ERP we cannot work with files on the AOS drive anymore. It was pretty usual to have file-based integrations in AX where you got a file in a folder and processed it.

Of course it’s still possible to work with files, for example from a storage account on Azure like Miquel Vidal has shown in his blog (in Spanish) or with the Recurring Integrations Scheduler tool.

Unzip .NET Streams

Most of the functionalities that consist in uploading of downloading a file is MSDyn365FO use .NET Streams, usually its child class MemoryStream.

So, how do we unzip one of these files? For example, the ISO20022 vendor payment journal file is zipped. What if we need to access the XML file contained in the ZIP?

We’ll need to use the ZipArchive class from System.IO.Compression namespace, and it’s really really easy. For example:

Edit: this code is valid for a single file ZIP. If the zipped file contains more than one file you must process each Stream inside the while.

We need to copy the unzippedStream stream (which is a DeflateStream) to a MemoryStream (which must be initialized) before returning it.

Remember that to access a .NET collection we need to use an enumerator to loop through it. If you don’t see the methods in the lookup using dot notation just write them, writing .NET code in X++ is still a bit buggy…

A warning about Self-service environments: update carefully

It looks like the time has finally come and all new LCS projects will have self-service Tier 2+ environments. If you want to know a bit more about them, I wrote this post about service fabric/self-service environments in Microsoft Dynamics 365 for Finance and Operations.

The last two projects we’ve started at Axazure are on self-service and we’ve had a customer migrated to it. So it’s about time I warn you about one scary thing…

Self-service !

Calling the LCS Database Movement API in your Azure DevOps pipeline

You can read my complete guide on Microsoft Dynamics 365 for Finance & Operations and Azure DevOps.

I talked about the LCS Database Movement API in a post not long ago, and in this one I’ll show how to call the API using PowerShell from your Azure DevOps Pipelines.

What for?

Basically, automation. Right now the API only allows the refresh from one Microsoft Dynamics 365 for Finance and Operations environment to another, so the idea is having fresh data from production in our UAT environments daily. I don’t know which new operations the API will support in the future but another idea could be adding the DB export operation (creating a bacpac) to the pipeline and having a copy of prod ready to be restored in a Dev environment.

Add multi selection lookup to a SysOperation Framework dialog

First 2020 post! Happy new year! Yes, I know it’s already past mid January…

When you add a field to a SysOperation Framework Data Contract the lookup that the framework creates (if the EDT has a lookup) is a simple, single select lookup. Let’s see how to create a multi select lookup in MSDyn365FO.

The SysOperation Framework and MVC

But first of all a bit of an introduction! The SysOperation Framework was introduced in Dynamics AX 2012 to replace the RunBase Framework, and is used to create processes that will be run by the batch server. The RunBase classes are still around in Dynamics 365 for Finance and Operations. Some standard processes still use it while others use it to later call a SysOperations Framework class.

LCS Database movement REST API

You can read my complete guide on Microsoft Dynamics 365 for Finance & Operations and Azure DevOps.

Since last October we’ve been able to try the preview of Microsoft Dynamics 365 for Finance and Operations Database Movement API which allows us to list and download DB backups and start DB refreshes using a REST API.

If you want to join the preview you first need to be part of the MSDyn365FO Insider Program where you can join the “Dynamics 365 for Finance and Operations Insider Community“. Once invited to the Yammer organization you can ask to join the “Self-Service Database Movement / DataALM” group where you’ll get the information to add yourself to the preview and enable it on LCS.

Create an ISV license from a cryptographic USB token

This post is a product of not reading the full documentation. Lesson #1: read the docs thoroughly, or at least don’t stop reading when you think you’re done.

Publishing an ISV solution

One of the steps when you want to publish an ISV solution is generating the license for your customers. This license has to be signed  using an Authenticode certificate that will enable the solution, limit the number of users or set an expiration date.

DevOps ALM automation in Microsoft Dynamics 365 for Finance and Operations

You can read my complete guide on Microsoft Dynamics 365 for Finance & Operations and Azure DevOps.

I’ve already written some posts about development Application Lifecycle Management (ALM) for Dynamics 365 for Finance and Operations in the past:

The possibility of doing real CI/CD is one of my favorite MSDyn365FO things, going from “What’s source control?” to “Mandatory source control or die” has been a blessing. I’ll never get tired of saying this.
