Tech Off - Thread Safe Singleton Pattern - C# ???

offwhite — Sun, 15 Jul 2007 00:21:35 GMT

Use a private method with an attribute to handle the locking to create the instance.

public static Singleton Instance
{
get
{
    if (_instance == null)
    {
      InstantiateSingleton();
    }
    return _instance;
}
}

// requires using System.Runtime.CompilerServices
[MethodImpl(MethodImplOptions.Synchronized)]
private static void InstantiateSingleton()
{
if (_singleton == null)
{
    _singleton = new Singleton();
}
}

You may want to just jump to Visual Studio 2008 once it comes out. It has a multi-targeting feature that allows you to target .NET 2.0, 3.0 and 3.5. I expect they will try to keep this going for future versions of the framework.

Also, if you like ASP.NET 1.1 projects you can use Web Application Projects which were included with the latest service pack for VS 2005.

Look that here...

You may want to give the Website Projects (not Web Application) a try. That was the model that was intended for ASP.NET 2.0 and it does have some features that you cannot get the other way. One is page-level compilation which is great during development. You can work on a single page at a time and when you want to preview it you do not have to wait for the whole website to compile.

Coffeehouse - Google’s monopoly

The point of forcing MS to open up Windows to competition is because MS can make it hard for competitors to offer the alternatives. By locking out products they fortify their monopoly.

But with Google, there is absolutely nothing forcing you to use their website. You can just as easily go to Live.com. And in Firefox you can add your own custom search provider. It is very easy to do and you could even add one for Live.com and make it your default. I set up one to search MSDN.

The problem with the monopoly is that it kills competition.

Coffeehouse - I soooo need to get out more...

That is from the Legend of Ron Burgundy. The character Brick looked around the room for things when he was asked if he loved anything. One was lamp.

Then they started singing "Sweet Afternoon Delight" together which was just very weird. But that is what you get from Will Ferrell.

Coffeehouse - Orcas and System.Web.Extensions

And remember that ASP.NET AJAX Extentions was not a part of .NET 3.0. It is an add-on to the framework so it was not treated like WCF, WF and CardSpace which is installed with .NET 3.0. Your hosting provider may just need to install the AJAX Extensions and drop the assembly into the GAC.

Try putting the assembly into the bin folder of your website and referencing it locally. If you eventually get an error about an ambiguous reference you will need to remove the one in the bin folder.

Coffeehouse - Visual Studio 2008: Impressions.

I agree about opening multiple solutions in a single running copy of VS, although I would only want to do that if 1) it saves overall memory from running muliple copies of VS and 2) if it was easy to switch between the solutions. I assume that if multiple copies of VS are running it does not need to load the same assemblies into memory which takes up more memory. But I would not want them to attempt this if it complicated the IDE too much. I know they are already juggling a million features. I will take performance and stability over a few more features.
