Question Julian Matthews · Dec 31, 2025

Hey everyone.

I have been taking a look at the External Language Server functionality to hook into some Dotnet functions, and I am hitting a bit of a wall.

Based on the example in the documentation here I can get the same result doing:

ENV>Set netGate = $System.external.getDotNetGateway()
ENV>Set netProxy=netGate.new("System.DateTime",0)
ENV>Write netProxy.Now,!

However, if I then try another system class, I get an error:

ENV>Set netGate = $System.external.getDotNetGateway()
ENV>Set netProxy=netGate.new("System.Convert",0)
ENV>Write netProxy.

I am migrating from HealthShare 2015 to Health Connect 2025 as part of an infrastructure upgrade. We have several C# .NET Razor web apps that interact with HealthShare using the InterSystems.Data.CacheClient assembly, and the Cache Object Binding Wizard for .NET to build the C# proxy classes. This has worked flawlessly for about 6 years.

I am now switching to using the Native SDK with the InterSystems.Data.IRISClient assembly and using the C# IRISReference and IRISObject.

One of the newest features of .Net core 10 with C# 14 is the file-based apps. This feature allows you to execute C# code in a simple .cs file without the need to create a solution, a project, or any of the related structure.

For example you can create a script.cs file using the notepad with the content: 

Console.WriteLine(“This is a script in c#.”);

Then in the command line or the terminal you execute the command:

dotnet run script.cs

There is plenty of information about this new feature of .net 10.

Question Mark Lierman · Jul 18, 2025

I'm following this guide as well as the sample.cs file and getting an error message on this line
cache_connection.Connect();

The error is:
Caught GlobalsException: lc_conn::connect_device returned Db_err: source: lc_conn::connect()  message: lc_conn::connect: CacheSecureStart returned -15: <ACCESSDENIED>

I've tried many variations of Namespace + Username + Password and they all result in that error, even though I can connect to the namespace just fine using other means.
