Using .NET 3.5 features without installing .NET 3.5

by Aaron Powell 23. February 2010 03:48

I recently worked on a project for a client which the deployment environment was only to have .NET 2.0 installed. This is a rarity these days, after all .NET 3.5 was released in November 2007 (http://en.wikipedia.org/wiki/.NET_Framework#.NET_Framework_3.5), so having chosen to not install it is a bit of an effort.

But fine, what ever floats your boat I guess, but there is a problem, pretty much all the libraries which we’ve developed at The FARM are .NET 3.5 libraries, generally because they use features like LINQ or Extension Methods.
Damn, that’s going to be a pain in the ass, I’d either have to forgo our libraries, or make custom versions of them.

Or, I could be a bit ninja-esq and make a .NET 2.0 website, which has .NET 3.5 assemblies in it, now that sounds like fun.

But let’s step back a bit, what is .NET 3.5 in relation to .NET 2.0?
Well really .NET 3.5 is a super-set of the .NET 2.0 framework (well, technically a super-set of .NET 3.0, which itself was a super-set of .NET 2.0, but you get the idea). But why is that? Well .NET 3.5 is built on top of the same CLR (Common Language Runtime) which powers .NET 2.0.

Since most people associate .NET 3.5 with Visual Studio 2008 so I’ll talk about them in a combined manner.

In addition to the .NET 3.5 release we also received the C# 3 compiler. This nifty little bugger brought along the translation of => to being either a Func, Action or Predicate, and it also introduced the var keyword.
But the fun thing is that because C# 3 is targeted at the 2.0 CLR all the compiled IL is perfectly valid for .NET 2.0! This is actually how (and why) multi-targeting in Visual Studio 2008 works (well, how and why at a very high level :P) and why you can use var, lambda, etc in a .NET 2.0 project provided it’s made in Visual Studio 2008.

But back to our original topic, how do I use .NET 3.5 without installing it on the server? (Note – you’ll still need it installed on the dev environment)

Putting the pieces together

So we’ll create a new ASP.NET web application, still choosing .NET 3.5 as the framework version and do everything as per normal. The tricky part is when we come to wanting to deploy the site onto our target environment, which doesn’t have .NET 3.5 installed.
Before we can do this there is one last thing we need to change within Visual Studio, you need to change the way the Visual Studio handles the referenced assemblies. Framework assemblies (well, any assembly which is in the Global Assembly Cache (GAC)) are set to Copy Local=False, you need to change this to True, so right-click the assembly and go to Properties:

properties

Now what will happen is that when the compile is done the assembly/ assemblies will be copied into the /bin folder of your site, meaning now they are loaded into memory, but not loaded there from the GAC!

You can then take all the files and deploy them to the target environment, with the .NET 3.5 assemblies in the /bin folder, but not installed.

Really a great trick with Shared Hosting ;)

Umbraco 5th birthday meetup in Sydney @ TheFARM

by Shannon Deminick 12. February 2010 11:39

Come on down to TheFARM to share in some beers and take part in the global Umbraco 5th birthday festivities.

Your hosts will be core Umbraco team developers Shannon Deminick & Aaron Powell, both of whom work for TheFARM (http://www.thefarmdigital.com.au).

The plan is for Shan and Aaron to run a Q&A session with some demo’s of the fun stuff TheFARM has been doing with Umbraco 4.1 and the work they have been doing on this next release.

  • They'll have a look at all of the new features/fixes for 4.1 (are there are TONS)
  • They'll go into a bit more in detail on some of the new things that we've integrated into the core such as LINQ to Umbraco, Umbraco Examine, new controls, enhancements, preview, etc…
  • They’ll show you some of the sites we’ve built and talk through some of the implementation’s with things like Flash

Hopefully, with two of the core team on hand we should be able to answer most questions thrown at us – give us a go!

Once we're out of beers... TO THE PUB!

All of the details, address, etc.. is on the Our Umbraco website. Have a look and RSVP now!

More on Umbraco, TinyMCE and Flash

by Aaron Powell 3. February 2010 10:05

In a previous post Shannon explained how to customise TinyMCE for what HTML elements Flash actually supports, and he finished off the post with showing how to cleanup line breaks.

To do this he used an XSLT function called normalize-space, which is great if you’re using XSLT!

I was writing a service today which was using LINQ to XML to generate the XML for Flash, but that posed a problem, how do you deal with Flash wanting to do hard breaks on new line constants?

Easy, string.Replace to the rescue!

Here’s a handy little extension method you can drop into your code libraries:

public static string NormalizeSpace(this string s) {
	if(s == null) throw new ArgumentNullException("s");
	return s.Replace("\r\n", string.Empty)
		.Replace("\r", string.Empty)
		.Replace("\n", string.Empty);
}

Nice and easy (and unsurprisingly logical!).

Freeing up space on your server

by AnthonyDang 3. February 2010 06:24

Yesterday we went to install service pack 2 on a Windows  Server 2008 machine. It turns out you need at least 5GB free on C: which we didnt have. After deleting everything we possibly could, including running CCleaner and making the Page File non-existant we were still 400MB off the mark.

 

 Then I noticed a system file c:\hiberfil.sys which was 3GB.

 

Well it turns out that Windows Server 2008 still allocates space for a hibernate file. Who would want to hibernate their Live server?

 

Anyway, this is how to gain an exta 3GB...

 

C:\Users\Administrator>powercfg.exe /hibernate off

 

That's it!
