MsTest Command Line Referenced Assemblies
This was a small issue i came across the other day, just thought would add a note about it like i usually do. Problem When running my tests in visual studio everything is fine and they all pass. In this particular case they were actually BizUnit tests where some of my steps use a proxy class which i have created and is in a seperate assembly. In my assembly where i have my tests i have just added a reference even though my code does not directly use the assembly i reference. The problem is when i ......

Microsoft WMI Code Generation Tool

I hadnt seen this anywhere before, but a collegue pointed me at it and i must say am very impressed.  It basically lets you view the WMI Classes then generate code to use them

It is very handy when working on BizTalk utilities

One to watch for with WSE Filters
Scenario I am currently working on a project where one of the things we deliver is a web service exposed by BizTalk which allows other applications to interact with one of the legacy systems. The service is consumed primarily by a .net application being developed on another project within the same company. When trying to consume the service the developers of the .net application were recieving an error and with BizTalk being involved the usual case of blaming BizTalk as it is this strange mystical ......

I hate the visual studio configuration manager
We all have things in the development tools and processes that bug us and this is one of mine. Why am i blogging about this? - To relieve some frustration - On the off chance that someone might read this who can do something about it ;-) What is the configuration manager? The configuration manager is that tool in visual studio that allows you to configure what mode different projects are in. See diagram. Why does it bug me? Most of these bug me's are related to things i have come across in BizTalk ......

Kerberos Adventures - Problem: Exposing an Orchestration from BizTalk with the WSE 2 Adapter and using Kerberos
Scenario I was trying to implement the requirement to use Kerberos to sign and encrypt the messages to and from a web service which was generated using the WSE 2 Web Service Publishing Wizard to expose a BizTalk Orchestration as a web service. Problem I had this all setup as I expected to work. The SPN and everything seemed correct but when I called it I kept getting the following error message: System.Web.Services.Protoco...

Creating a new project/solution
Problem Ok this is one the biggest pains in the butt to me when working with Visual Studio. Normally on projects ive use a nested folder structure which matches the namespaces within the solution. The problem is that when you create a new project it will put it in a new folder under the folder where the solution file is or which ever directory you select, and the new folder is always the full name of the project. In the end you just end up having to move the project file to the place you want it ......

Kerberos Adventures - Problem: 401 Unauthorised - User equals null
Scenario We were trying to implement a delegation scenario similar to the one in the POC (Web Services using Delegation). While implementing this we came across the problem where we seemed to not be passing the clients credentials. We constantly got the IIS 401 Unauthorized return code. Symptoms In this example we got some of the following symptoms: In the IIS Log of the back end service there would be no credential specified. When calling the back end service locally on the machine where it sits ......

Kerberos Adventures - Problem: Error consuming web service from Windows XP SP2 client
Scenario We have a windows XP Client which is calling a .net 2 Web Service which uses WSE 2.0 SP3 on a remote Windows 2003 Server.

In this series of posts I intend to provide a step by step guide for setting up each of these scenarios. Or if there is a sufficient walk through already available I will point you to that.

Kerberos Adventures - Introduction
I am currently on a medium - large sized project where one of the things we are planning to do is use BizTalk and Web Services. Within the architecture we have plans to support credential flow across tiers. It has proven quite difficult to get this working and then doing things with BizTalk has added an additional twist which also proved tricky. During the course of working on resolving our issues and also setting up these proof of concepts I have found that there is useful information out there ......
