The test assertion was:


It Should_be_add_a_message_to_the_contractor_conversation = () =>
{
Assert.That(_contractor.Messages, Has.Some.InstanceOf().And.All.With.Property("Content").EqualTo(messageContent));
};


Changed to:


It Should_be_add_a_message_to_the_contractor_conversation = () =>
{
_contractor.Messages.ShouldContainAny(m => m.Content == messageContent);
};

The extension method:


public static void ShouldContainAny(this IEnumerable list, Func comparer, params T[] items)
{
if (items.Any(comparer))
{
throw new SpecificationException(string.Format(@"Should contain any matching item but contains none"));
}
}


Using the standard web config transforms, e.g:

In App.config

 <connectionStrings>
    <add name="Db" connectionString="Server=localhost;Port=3306;Database=myapp;
Uid=myappuser;Pwd=secret;/>
  </connectionStrings>

In App.Production.config

 <add name="Db" connectionString="Server=production;Port=3306;Database=myappprod;
UId=produser;Pwd=supersecret;" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>

This will transform your out so you have a production config file which overrides the standard config file. as documented here:
Web Config Transforms

But what if you need the config shared across projects, e.g. Unit Testing, Integration testing, Tasks project etc…

Well you can use the standard Linked file approach, where you Add an existing item but select the little drop down on the add button.
The project file items will look like below.

<ItemGroup>
	<Content Include="..\Shared\App.config">
	<Link>App.config</Link>
	<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Content>

<Content Include="..\Shared\App.Local.config">
	<Link>App.Local.config</Link>
	<DependentUpon>App.config</DependentUpon>
</Content>

<Content Include="..\Shared\App.Staging.config">
	<Link>App.Staging.config</Link>
	<DependentUpon>App.config</DependentUpon>
</Content>

<Content Include="..\Shared\App.Production.config">
	<Link>App.Production.config</Link>
	<DependentUpon>App.config</DependentUpon>
</Content>
</ItemGroup>

<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
<Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.targets" />

<Target Name="PostTransformAppConfig" AfterTargets="TransformWebConfig">
	<Copy Condition="Exists('$(TransformWebConfigIntermediateLocation)\transformed\App.config')"
                  SourceFiles="$(TransformWebConfigIntermediateLocation)\transformed\App.config" DestinationFiles="$(OutputPath)\App.config" />
	<Copy Condition="Exists('$(TransformWebConfigIntermediateLocation)\transformed\App.config')"
                  SourceFiles="$(TransformWebConfigIntermediateLocation)\transformed\App.config" DestinationFiles="$(OutputPath)\App.config" />
</Target>

Then Just Call:

  msbuild myproject.proj /t:TransformWebConfig /p:Configuration=Production

And the output will be

 <add name="Db" connectionString="Server=production;Port=3306;Database=myappprod;
UId=produser;Pwd=supersecret;"/>

Error 1
The virtual path ‘/Views/Shared/Site.Master’ maps to another application, which is not allowed. C:\temp\Views\Cart\New.aspx

this didn’t really help me, some searching said stuff about IIS mappings etc… anyways it turns out to be very simple… one of my views had a missing tilde ~

“/Views/Shared/Site.Master” i changed it to   “~/Views/Shared/Site.Master” and the problem was gone…

as i said what a waste of time !!!!

What a waste of an hour…   I was running an asp.net mvc app  on my VMWare Fusion VM, with Windows 7 RC & IIS 7. When i kept getting this error:

System.Security.SecurityException: Request for the permission of type ‘System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′ failed.

The thing that threw me off was that it only seemed to happen doing certain stuff, like the mvc future strongly typed links and html helper submits..

<% Html.SubmitImage(…..

Also if you search for posts/forums on it you;’ll bump into the UNC path issue, which again threw me a little.. “was it because of my VM, was iis seeing my C drive as a share?” crazy talk but still that’s the kind of shit that goes through your head when debugging these kinds of issues…

Anyways in the end it was the identity that the Application pool for my site was running under, funnily enough  called “ApplicationPoolIdentity”.

I changed it to network service and all is fine..

check out this post which covers the issue…

Now that I’m back doing alot of CSS i came across a post describing the CSS formatting feature in visual studio…

My preference is for single line css. I dont like to expand to one line per rule, thats just my personal preference. But it can be a pain to maintain.

Enter visual studio:

here’s some code i had….

body
  {
      background: #123;
      border-top: 5px solid #000;
      color: #333;
      font-size: 11px;
      padding: 20px 0 40px;
  }
  a
  {
      color: #fff;
      text-decoration: none;
  }
  a:hover
  {
      text-decoration: underline;
  }
  h1
  {
      font-family: Georgia, serif;
      font-weight: normal;
      text-align: center;
  }

and with a quick Format!!!

body { background: #123; border-top: 5px solid #000; color: #333; font-size: 11px; padding: 20px 0 40px; }
a { color: #fff; text-decoration: none; }
a:hover { text-decoration: underline; }
h1 { font-family: Georgia, serif; font-weight: normal; text-align: center; }

nice….

now if only the formatter would make the rules alphabetical !!!!

I’ve been working with ruby for about 6 months now on and off but the majority of my development is still in C#. So i’ve been keen to try out the possibility of using IronRuby with C#. I think the mixture of both langauges is compelling as there’s cases where a dynamic language is a better choice, more flexible and faster (development time).

Also with ruby there’s a really good opportunity to build internal DSL’s fast, and with an elegant end product. You only have to look at ActiveRecord in rails:

class Post < ActiveRecord::Base
  has_many :comments
  validates_presence_of :text

  ...
end

class Comment < ActiveRecord::Base
  belongs_to :post
  ...
end

and RSpec:

describe "(empty)" do
    it { @stack.should be_empty }
    it_should_behave_like "non-full Stack"
    it "should complain when sent #peek" do
      lambda { @stack.peek }.should raise_error(StackUnderflowError)
    end
    it "should complain when sent #pop" do
      lambda { @stack.pop }.should raise_error(StackUnderflowError)
    end
end

to be fair with the increasing number of fluent interface API’s in the .net world the drive towards more understandable code is not the preserve of the dynamic people.  With tools like StructureMap,


registry.AddInstanceOf<IWidget>()
 .WithName("DarkGreen")
 .UsingConcreteType<ColorWidget>()
 .WithProperty("Color").EqualTo("DarkGreen");

we get a very intuitive, understandable API which is also a DSL as far as i’m concerned. But i still believe that ruby’s looser syntax allows us to build nicer looking DSL’s

I guess ultimately it’ll come down to how easy it is to use IronRuby with C#, how good the tooling is, for example RubyMine is a ruby IDE from Jetbrains (resharper) which provides refactoring support and with these guys on the case i feel confident that the ruby refactoring story will only get better.

I did a talk on Ruby/IronRuby for skillmatter a while back and speaking to everyone at the talk there was a consistent message, we like/love ruby, love the tools available, rspec, cucumber, rake etc but we really need stability & ide support.

Its arguable whether you need an ide, i used textmate for the majority of my rails dev, however i did find it alot easier once i started to use it in combination with rubymine. Textmate for cranking out the code (its gr8, no clunky huge ide in the way), but when things got messy (i.e. i couldnt figure out a problem) i was able to boot up rubymine and get the full visual studio like experience with debugging, break points, watches, hover over variables etc, all that good stuff.

So if we get this for IronRuby i.e. a texteditor (which there are already loads of, e.g. e-editior, notepad++ etc) and full visual studio support I think people would jump all over Ruby/IronRuby.

it drove me crazy for a while until i found this patch that sorted it out..

my conclusion, unless your a real css freak/hacker then save yourself alot of time and either use this or something similar such as yahoo grids – developer.yahoo.com/yui/grids ,   or 960 grids – http://960.gs

you’ll find a good example here:
