Embedding Assemblies

A colleague and I had an interesting problem this afternoon with running a .NET executable we had created from within a Wise authored MSI. Basically the exe collected some values from a custom form and did some processing on them. The exe had a reference to an assembly that contained some functionality we needed so didn't think twice about adding a reference to it.

However the MSI would bomb out with a missing file exception to the referenced assembly. The console window that popped up showed the exe was extracted and copied to C:\Windows\Install (hidden folder) and executed there - obviously the referenced assembly was nowhere in sight.

A bit of rummaging around on Google and came across this life-saver on how you can implement an assembly resolver to load an assembly you have added as an embedded resource to your exe once the usual assembly locations have been searched by the framework and turned up empty.

There are a few issues with it if you read the comments but it saved my bacon on a 10 line installer utility app so it'll do for me - it's gone into the toolbox for future use that's for sure - thanks Jerry!

James -

Glad to see that helped. Like you mentioned, and as the comments to the post point out, it's not a perfect solution, but it isn't meant to be.

Walk-Thru: Using Wolfpack to automatically deploy and smoke test your system

First, some history... The advent of NuGet has revolutionised many many aspects of the .Net ecosystem; MyGet, Chocolatey & OctopusDeploy to name a few solutions building upon its success bring even more features to the table.

I also spotted that NuGet could solve a problem I was having with my OSS System Monitoring software Wolfpack; essentially this is a core application framework that uses plugins for extension (Wolfpack Contrib) but how to unify, standardise and streamline how these plugins are made available? NuGet to the rescue again - I wrapped the NuGet infrastructure (I deem NuGet to be so ubiquitous and stable that is has transcended into the software "infrastrucuture" hall of fame) with a new OSS project called Sidewinder. Sidewinder allows me to wrap all my little extension and plugins in NuGet packages and deploy them directly from the Wolfpack application - it even allows me to issue a new version of Wolfpack and have Wolfpack update itself, sweet huh?

Resharper add-in idea - highlight IDisposable vars

[Update 18th July 2013]
@RobGibbens and Greg Hurlman picked up on this - Rob pointed out that there is an FxCop rule that can do this and Greg suggested a Visual Studio extension. I've had a quick look at the Visual Studio options and it looks like an "Editor Extension" is a good fit....hmmm, Project New, click...doh...dammit I really don't have time for this but it looks a fun little diversion! I'll update here if I get anything working.

Had an interesting idea for a Visual Studio Resharper add-in the other day but don't have the time to implement it so thought I would put it out there...it might already exist (and hopefully someone can point me in the right direction) or someone will build it (Darren Voisey where are you?!).

The idea is very simple really - when you have a variable for an object that implements IDisposable it gets highlighted or a tell-tale is displayed to let you know it should be disposed or should be wrapped in a using sta…

Geckoboard Countdown Widget v2

v2 is here, now with added colours! This time using the RAG Numbers widget to display your date countdown - as you get nearer the date the number will change from green to amber then red.

The new url is: http://geckocountdown.appspot.com/rag/?date=2010-12-25&tz=0&msg=Days+to+Xmas!
Note 1: notice the new /rag/ path and the msg querystring param.
Note 2: the original v1 url still works


To use this on your Geckoboard add a new "Custom Widget/RAG Numbers" widget. By default the number will turn amber at 10 or less days to go and red at 3 or less days to go however you can change these with the querystring (see below).


Required querystring params
date: "yyyy-mm-dd" format, this is the target date to countdown totz: timezone offset in hours from GMT that you are in. Can be negative if you are behind GMT
Optional querystring params
msg: the label that appears next to the number of days (remember to encode spaces as +). The default is "Days Remaining" if you…
