Fortunately, quick Google turned up an answer. Just change your options in the Management Studio, see screenshot. Obviously, you wouldn’t want to be doing this on a production table!

An unhandled exception of type ‘System.InvalidOperationException’ occurred in System.ServiceModel.dll

Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http].

…

Could not find a base address that matches scheme net.pipe for the endpoint with binding NetNamedPipeBinding. Registered base address schemes are [http].

Given that my code was copied almost directly out of Microsoft’s very helpful Getting Started Tutorial I was a little confused.


Uri BaseAddress = new Uri("net.tcp://localhost/test");

// Step 1 of the hosting procedure: Create ServiceHost
ServiceHost SelfHost = new ServiceHost(typeof(SensorServiceProvider), BaseAddress);
try
{
// Step 3 of the hosting procedure: Add a service endpoint(s).

////Named pipe endpoint
SelfHost.AddServiceEndpoint(
typeof(SensorServiceContract),
new NetNamedPipeBinding(),
"pipe");

//TCP endpoint
SelfHost.AddServiceEndpoint(
typeof(SensorServiceContract),
new NetTcpBinding(),
"tcp");

// Step 4 of the hosting procedure: Enable metadata exchange.
ServiceMetadataBehavior mex = new ServiceMetadataBehavior();
mex.HttpGetEnabled = true;
SelfHost.Description.Behaviors.Add(mex);

// Step 5 of the hosting procedure: Start the service.
SelfHost.Open();
}


A good half-hour of Googling turned up a variety of possible causes for this exception, none of which turned out to be my problem. I finally found some sample code that revealed the issue, if you haven’t noticed already. The base address is using http, but neither the named pipes or tcp endpoints use this protocol. Changing “http” to “net.pipe” or “net.tcp” will enable the named pipes or tcp endpoints, respectively. And so it would appear I need multiple ServiceHost objects to enable named pipe and tcp access to my service concurrently. (Which will require a singleton and more documentation reading.)

Simple enough, but I’m just starting and it’s easy to miss stuff like this, so I though I’d share and hopefully save the next beginner some head scratching time.

Another problem I have with EA is that by default the links between UML elements in diagrams route directly, ie they form a spider webs of straight lines from one element to another. This looks horribly unprofessional. Rather than right clicking each link and selecting routed routing, it’s possible to change the default behavior of links. In EA, select “Options” under the “Tools” menu. In the Options dialog, select “Links” on the left, and change the routing option to “Routed” as shown in the highlighted area below.

UPDATE: The installer has since been updated to 1.35.

I’ve built installers before but overall am not very knowledgeable on the topic. I’m probably not using the correct terminology and I may have made other mistakes, but the core question here is sound. Back to to the question at hand…

This forum post claims it is Microsoft’s fault or the developer’s fault. (I think)

There is official documentation from InstallShield regarding the problem.

My understanding of the problem is that the MSI (Microsoft Installer) engine (by default) verifies all the Personal paths in the registry, even if they’re not needed. For example, “My Music” and “My Pictures” are personal directories who’s existence would be verified but obviously aren’t needed. This turns into a real problem when you’re like me and have these non-essential directories re-located on an external or network drive. Basically, I can’t install or uninstall without my external drive plugged in.

What I don’t understand (based on those links and the several others I found using Google) is if the MSI engine will try and verify those paths regardless, or if it only does so by default and that it’s possible to only verify the necessary paths when configured properly?

Does anybody know if this is a bug, or if it’s the installer builder’s fault?

In terms of personal interest, WSD or Web Services on Devices looked the most promising as I was already planning on implementing similar functionality by hand. However, I have to wonder if video calling over IP wouldn’t be a great addition to the project so the end-user can receive live support and actually look at a person.

The end of the presentation was what I found the most generally interesting, it looks like Microsoft is going somehow bring the cost of dev boards way down for general hobbyists, and include a FULL version of Visual Studio 2005 as part of the package. Enabling regular people to work on that embedded idea they’ve been kicking around in an environment that’s as user friendly as Visual Studio is a “good thing”. However, I have to wonder if it isn’t an attempt to poach some developers from the Linux camp. Even if it is a big Microsoft plot, offering developers more choice and competition in the marketplace benefits everyone.

From now on I’ll be looking for some real details, hopefully information starts trickling out on the web.

From [SteelPrice.net](http://blog.steeleprice.net/archive/2006/06/15/880.aspx)…

* Licensing – Free (essentially the same as SQL Express) now available on XP/2003/Vista as well
* Database Size Limit – 4Gb (not set in stone, but most likely)
* Runtime Size – 1.4Mb – running In Process with your App (including Office Apps for VSTO developers)
* This means no server to install, just some DLLs that are independent from anything else and can just be added/removed without harming any other app on your system.
* Single Data File(.sdf) – no transaction log, etc.
* Sync with a backend SQL Server through Merge & Replication – (More than just RDA soon)
* Differencing Tools in the ADO.NET extensions (MergeUpdated(), MergeInserts(), MergeDeletes())
* Complete control over collision handling so you can choose client wins, Server wins or create a custom solution because you have access to both sides of the colliding row.
* Multi-connection support so you can run multiple background processes on the same file.
* Windows can handle the ACL on the file so you can lock the file to a group of domain users, etc.

This looks like a great opportunity for anybody interested in .NET. (Like me!) Too bad I’m already taking too much time off from work. The website doesn’t list rates, so it’s possible it’s free for attendees.

> If you are a language designer, compiler writer, or tool builder in industry or academia, Lang.NET 2006 is a unique opportunity to directly interact with the architects of Microsoft language platforms.

This would imply that the discussions will be in-depth and technical, but I imagine still interesting for someone without the background.
