Presenter: Jeff Semmens Task: Model and access data as objects in .NET without designing the database first Approach: Use InterSystems Entity Framework
Description: Come and experience how you can design your database model in .NET and evolve it over time by leveraging the Entity Framework.
Problem: Current bindings require database-first design. I cannot design my model in .NET.
Solution: The Entity Framework is an object-relational mapping framework that allows data-oriented applications to model and access their data as objects in .NET. Database- first is still supported but will fade away in future releases.

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 new to cache, come from an oracle and sql server background. In oracle and sql server I could write basically a stored procedure like script and pass it in as text to the command to execute.
Example:
Below would be the _sqltext
DECLARE @Id INT;
select id into @Id from something;
if @Id = 9
BEGIN
do something
END
The _sqltext would work in sql server, what would be the equivalent for cache for it work?

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.

I have updated some legacy VB/ASP.NET code and changed the references of InterSystems.Data.CacheClient to InterSystems.Data.IRISClient. I am struggling with the code as I am not a .NET expert and there is little or no documentation.

IRISReference valueRef = new IRISReference(""); // set inital value to null string
iris.ClassMethodString("%SomeClass","SomeMethod",valueRef);
String myString = valueRef.value; // get the method result
I'm using this Dockerfile to build .Net Gateway with my PEX BS. It works fine. If I change the image reference here to store/intersystems/iris-community:2021.2.0.617.0 in line 8 (so update from 2020.2 to 2021.2) it fails to build with:
