Hi,

I'm trying to use the message queue namespace, but I get the following
error:
CS0234: The type or namespace name 'Messaging' does not exist in the class
or namespace 'System' (are you missing an assembly reference?)

I'm using this line in my page:
<%@ Import Namespace="System.Messaging" %>

I have Message Queue installed on my box. What am I missing?

thanks,

Ray,

Do you have a reference to the System.Messaging.dll?

Ray,

You need to explicitly reference the System.Messaging.dll assembly in the
Web.Config (or machine.config) file. Open the Web.Config file and find the
section labeled <assemblies>. You'll need to add a reference to the
System.Messaging.dll assembly there.

-- Hope this helps

Can you explain to me why? How come I don't have to do that with other
assemblies? Thanks for your help.

Hi Ray,

Only certain assemblies are referenced by default in the Web.Config file.
Here's what mine looks like by default:

<assemblies>
<add
assembly="mscorlib" />
<add
assembly="System, Version=1.0.2411.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089" />
<add
assembly="System.Web, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add
assembly="System.Data, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<add
assembly="System.Web.Services, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add
assembly="System.Xml, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<add
assembly="System.Drawing, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add
assembly="*" />
</assemblies>

Notice that each assembly is explicitly referenced. The final assembly="*"
directive is for all the assemblies in your application bin directory. To
get System.Messaging to work, you need to modify this section to look like
this:

<assemblies>
<add
assembly="mscorlib" />

<add
assembly="System.Messaging, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

<add
assembly="System, Version=1.0.2411.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089" />
<add
assembly="System.Web, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add
assembly="System.Data, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<add
assembly="System.Web.Services, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add
assembly="System.Xml, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<add
assembly="System.Drawing, Version=1.0.2411.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add
assembly="*" />
</assemblies>

I have several examples of using Message Queuing in my upcoming book,
ASP.NET Unleashed. I've been putting up code samples from this book at the
Superexpert Web site (www.Superexpert.com) if you are interested.

-- Best,
Steve
