NET Framework (pronounced dot net) is a software framework developed by Microsoft that runs primarily on Microsoft Windows.

Official site.

.NET support in InterSystems Data Platform.

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,

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?

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.

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

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.

Error:

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

Native API , IRIS 2019 regression vs Cache .Net provider

1. checking the native API, with .net provider, from IS docs, I realize,

that it is not possible to wrap objectSricpt Class with .NET (C# for example) pure Class with it's methods/properties

and make pure instance syntax of: new myNetClass - as wrapper of irisClass.

as I realize, you can run .Net Class , only with .Invoke or iris.ClassMethodVoid("class.name","method")

such syntax, cannot execute event driven on proprety change, let say, with it's build in mechanizm in .Net

  iris.ClassMethodString("%SomeClass","SomeMethod",valueRef);
  String myString = valueRef.value;               // get the method result

But IRISReference is not available as a type.

Avoid $c(0) in globals

Good Morning,

I have this question for a long time. When I make an insert by SQL from an external application in the fields of type %String, if they are empty, it writes the character $c(0) in the global.

Is there a way so that if an Insert is received in a field of type% String with null value instead of the $ c (0) it leaves it empty?:

dotnet core

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'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:
