CAS Policy changes in .NET 4.0 Visual Studio Beta 2

I ran into a interesting exception yesterday when trying to run NServiceBus on Windows 7 with Visual Studio 2010 Beta 2

System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=131738 for more information.

I found some more info on this blog.

Basically the fix is to add the following to your App.Config

 <runtime>
    <loadFromRemoteSources enabled="true"/>
  </runtime>

Freeing Disk Space on C:\ Windows Server 2008

I just spent the last little while trying to clear space on our servers in order to install .NET 4.5 . Decided to post so my future self can find the information when I next have to do this. I performed all the usual tasks: Deleting any files/folders from C:\windows\temp and C:\Users\%UserName%\AppData\Local\Temp Delete all EventViewer logs Save to another Disk if you want to keep them Remove any unused programs, e.g. Firefox Remove anything in C:\inetpub\logs Remove any file/folders C:\Windows\System32\LogFiles Remove any file/folders from C:\Users\%UserName%\Downloads Remove any file/folders able to be removed from C:\Users\%UserName%\Desktop Remove any file/folders able to be removed from C:\Users\%UserName%\My Documents Stop Windows Update service and remove all files/folders from C:\Windows\SoftwareDistribution Deleting an Event Logs Run COMPCLN.exe Move the Virtual Memory file to another disk However this wasn’t enough & I found the most space was

3 Reasons Why Progressive Web Apps (PWAs) Won’t Replace Native Apps

Many people believe Progressive Web Apps (PWAs) are the future of the mobile web, but in my opinion, PWAs are not a replacement for native mobile apps. Here are three reasons why: 1. Native mobile apps provide a smoother & faster experience Mobile websites, progressive or otherwise are slower and not as smooth. 90% of the time spent is spent using apps vs the browser . The single most significant contributing factor to a smooth experience on mobile is the speed of the network and latency of the data downloaded and uploaded. When you visit websites on desktop or mobile, there is a lot of third-party code/data that gets downloaded to your device, which more often than not has zero impact on the user experience. This includes: CSS (Cascading Style Sheets) JavaScript Ad network code Facebook tracking code Google tracking code The median number of requests a mobile website makes is a shocking 69 . On the other hand, native apps only get the data that is requi

Unit Testing Workflow Activities in .NET 4.0

Recently during a catch up with my buddy Keith Patton I was (as I tend to do) singing the praises of the Workflow in .NET 4.0. The all important question about Unit Testing support was raised, I tried as best as I could to explain the new In and Out Arguments but I didn’t feel I was convincing enough, so I though I would clarify with a blog post. If you developed Workflows in .NET 3.5 then you will be well aware of the lack of Unit Test support which was due to many reasons but mostly in part to the complex Workflow hosting environment. When moving to .NET 4.0 Workflow Foundation from .NET 3.5 it pays to be conscious of that fact that there is no longer a distinction between Activities and Workflows. Everything derives from the System.Activities.Activity class. So the definition of a Workflow is just a collection of of 1 or more Activities. I have designed a very simple Rental Car Activity which takes the an Applicants age as the input and outputs a True or False depending o
