Consume messages via powershell

[Patrick von der Hagen]

Hi all,

need to use powershell to read messages from RabbitMQ. Usually I prefer Python or Java, but since I have to invoke some powershell-commandlets, I'm trying powershell instead.

Problem: when doing

[System.Reflection.Assembly]::LoadFile("C:\temp\RabbitMQ.Client.dll")

$factory = New-Object RabbitMQ.Client.ConnectionFactory
#Verbindungsdaten für den RabbitMQ Server
$factory.HostName = $hostname

I run into an exception:

The field or property: "uri" for type: "RabbitMQ.Client.ConnectionFactory" differs only in letter casing from the field
or property: "Uri". The type must be Common Language Specification (CLS) compliant.


I had a look at PoshRabbit, but it has some issues and is probably unusable in my setup.

Any help would be greatly appreciated.

Yours,
Patrick.

I’m not knowledgeable enough of PowerShell but I’m curious how do things work in other
scenarios?

This is the first time I see this conflict reported.

I guess you can write a tiny wrapper app that uses the .NET client .

Don't know where to get a Visual Studio (or a windows desktop) on short notice, so a wrapper is not an option.

But a colleague had to create a powershell-client one or two years ago. The dll he has been using identifies as "RabbitMQ Client Library fro .Net", "Copyright @2007-2013 GoPivotal, Inc." and works fine.

I forgot: Windows 2012R2, Powershell 4.0. The DLL I'm currently using identifies as 2.0.50727 when I perform LoadFile.

Newer versions of the client require newer .NET versions and have API changes.

You can download older versions in the archive:

The OS is Windows Server 2012r2. Default .net-Environment is 4.5 and default powershell is 4.0. AFAIK version 4.0 of powershell does not imply it is not using .net 4.5, but I failed to find any specific information.
