Some readers of my previous article, Caché eXTreme for .NET - direct access to globals from C#, wondered if you could access information not just from the same instance in which you’re working, but also from another instance on the same computer, or from an instance located on another computer in the same local network. Some theorized, correctly, that this would be possible using the Enterprise Cache Protocol (ECP). In this article I’m going to show how it can be done.

Recently I came across a very strong statement to the effect that InterSystems.Data.CacheClient.dll library works fast because it does not open a TCP/IP connection, instead it works in the same process as a database. It made me pause for quite some time. Firstly because .Net Managed Provider, which utilises this library, opens TCP/IP connection to the database (and it is stated in the documentation "Using .NET and the ADO.NET Managed Provider with Caché"). And secondly, because as far as I know only eXtreme applications attach themselves to the process.

Microsoft Office has components for using in third party applications: COM Objects for C++ and Interop Assemblies for .Net programming.

Many Cache projects used to include calls to those libraries. However, recently this solution started being problematic.

There are two main reasons - legal and technical. Let’s check the details.

Microsoft technology support

Microsoft is supporting Office Automation only for desktop computing.

It shall not be used for server computing, as they offer Sharepoint for this scenario. Have a look here:

Hi,

We are developing a .NET6 application using Iris database. We would like to use ORM for easier code maintenance.

I saw a doc about Entity Framework: https://docs.intersystems.com/iris20231/csp/docbook/DocBook.UI.Page.cls?KEY=BNET_eframe, but even it's newest Iris version, the Entity Framework is very old .NET Framework (2013) and not supported by Microsoft anymore. Are there any plans to support Entity Framework Core?

We are updating a C# module which creates consumes an OdbcConnection from System.Data.Odbc. This module used to create a DSN-less connection through the InterSystems Cache driver, and we are updating it to call the IRIS ODBC35 driver following migration of the target database.

The Cache connection was formed formatted as follows:

Hi

I am upgrading our application from dotNet Framework to dotNet Core.

Prior to the upgrade I was able to connect to both my Cache & IRIS instances using the IRIS ADO.NET driver.

However, in dotNet Core, whilst I can connect to IRIS, I get the following error connecting to Cache.

InterSystems IRIS Provider is not compatible with Cache xDBC server

I am using the IRIS driver from the Windows (x86-64) 2022.1 distribution (the one in dev\dotnet\bin\net5.0).

The cache version is Cache for Windows (x86-64) 2018.1.2

Thanks

Question
· Jun 20, 2022
Visual Studio c#

Hi, I tried the following exercise from the IRIS documentation. I updated the username, password and IP address, but receiving this error;

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. --->

I can use the same credentials and IP address to connect ok via VSCode to my local IRIS...

Any pointers much appreciated.

Hello,

I have an error connecting the InterSystems cache with the odbc driver with the ODBC-2017.2.2.865.0-lnxrhx64.tar version using the ubuntu versions 20.04 and version 18.04 (which works with the .Net Core 3.1 version) with the Net 6.

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?

I get a generic error when I try it with cache

I'm building a .Net Core Gateway container. Here's the issue.

As a final step I'm building a .Net Core 2.1 library. It has a runnable dependency - .Net Gateway, which I need to start first.

However dotnet publish generates .runtimeconfig.json and .deps.json only for my library and not for my dependency (.Net Gateway).

Is there a way to force dotnet to generate .runtimeconfig.json and .deps.json for a dependency?

I have tried:
