Happy new year! I’m Raj Singh, InterSystems’ product manager for Developer Experience and I’d love your feedback on how you use IDEs today and your thoughts for the future.
The new $system.external interface (aka "InterSystems External Servers") is used to call/integrate with external language code/libraries, it replace the old gateways (for example Java gateway) that required the import of proxy objects.
Note that the documentation for the old gateways has been removed from IRIS, so only the new $system.external interface is somewhat (i.e. insufficiently) documented.
Regarding the migration from old gateway to new $system.external interface the documentation says:
InterSystems IRIS provides a complete application development environment for building sophisticated data- and analytics-intensive applications that connect data and application silos. It is designed to work with all of the common development technologies in an open, standards-based fashion and supports both server-side and client-side programming.
InterSystems IRIS 2020.1 includes PEX (Production EXtension Framework) to facilitate the development of IRIS Interoperability productions with components written in Java or .NET.
Thanks to PEX, an integration developer with knowledge of Java or .NET can benefit from the power, scalability, and robustness of the InterSystems IRIS Interoperability framework and be productive in no time.
New to coding in InterSystems IRIS® data platform? Try this brand-new learning program to get the basics, and see how to develop an application with InterSystems ObjectScript alongside your language of choice: Java, .NET, Python, or Node.js.
Integrating Cache with .net may be difficult, as we need to know both technologies and tools involved. Let’s follow the simplest possible example and see the pitfalls lurking on our way.
1. Creating .Net Assembly
.Net assembly is unit that contains compiled code and other resources.
Let’s create the simplest .Net assembly that will contain the code we want to execute.
We will use assembly of type Class Library, as we will use classes and their methods contained within. This type of assembly has .dll extension.
InterSystems states that Caché supports at least three data models – relational, object and hierarchical (globals). On can work with data presented in relational model in a program written on C# the same way one works with any other relational DB. To work with data presented by object model in C# one needs to use .NET Managed Provider or some kind or ORM. And starting with version 2012.2 one can work directly with globals (or use direct access to hierarchical data) via Caché eXTreme for .NET.
With the release PEX in InterSystems IRIS 2020.1 and InterSystems IRIS for Health 2020.1, customers have a better way to build Java into productions than the Java Business Host. PEX provides a complete set of APIs for building interoperability components and is available in both Java and .NET. The Java Business Host has been deprecated and will be retired in a future release.
In this installment of InterSystems IRIS 2020.1 Tech Talks, we put the spotlight on extending InterSystems IRIS with your own custom Java and .NET code. We will demo how to create a custom interoperability component with the new Productions Extensions (PEX) feature. Following that, we’ll demo how to call Java or .NET code from any ObjectScript code.
Imagine that your .NET project uses the Caché DBMS and you need a fully-functional and reliable authorization system. Writing such a system from scratch would not make much sense, and you will clearly want to use something that already exists in .NET, e.g. ASP.NET Identity. By default, however, this framework supports only its native DBMS – MS SQL. Our task was to create an adaptor that would let us quickly and easily port Identity to the InterSystems Caché DBMS. This work resulted in creation of the ASP.NET Identity Caché Provider.

Is there an InterSystems supported dotnet core library or community contributed repo on the horizon? At this time we are exploring installing the ODBC driver in our containers but would rather use more robust solution.

I have Microsoft Visual Studio Community 2019 installed and tried to setup the entity framework as per Using Entity Framework with InterSystems IRIS Data Platform (https://learning.intersystems.com/course/view.php?id=1046) tutorial but I can't see the ISC data source in MS Visual Studio's Data source section. Does this mean that MS VS Community 2019 is not supported with the Entity Frmawork?
Thank you all for your continued feedback and support of our ad hoc reporting platform, VDM. There's been some questions around setting up a non-ODBC connection for InterSystems platforms. We published a new YouTube video showing the steps necessary to connect to InterSystems Caché and InterSystems IRIS with BridgeWorks VDM.
I'm converting a .NET gateway interface (call .NET code from IRIS) from the old "Caché style" that use imported proxy class to the new $system.external .NET gateway as documented in:
I am going to develop a ASP .NET Core Application. In that Hos can use IRIS Entity Framework. I searched but I couldn’t find IRIS Entity Framework for .Net Core . Please kindly help me to overcome this issue.
Our ERP solution runs on different sql databases (such as ms sql and posgre). We are using the same code for all plattforms, doing database-specific changes in the db driver for each type of database.
There is one function in our program, where the user can store long text to discribe something, which is used in print and web. This text is treated/stored as html and can include pictures. The pictures in the html are stored base64 coded inside the html and the html is stored as text in a column. In other database systems, this is treated as TEXT or BLOB, and workings just fine.
See how the Production Extension framework (PEX) allows you to build custom interoperability components in .NET or Java without first learning ObjectScript.
With PEX, you can code in a familiar language and take advantage of established code libraries to add components to a production.

What’s the contest about?
In the last year, InterSystems added and expanded Native APIs for Java, .NET, Python, and Node.js. The Native API provides high speed access to globals, the ability to instantiate and use ObjectScript objects, and fine-grained control over transactions.
