I instantly lookd at the third possibility. since I have Vista on board I was thinking about writing my own Sidebar Gadget (you know the little programs written in HTML an JavaScript, sticked to the right side of your screen). Of course I wonted it to by at least useful ;-) I thought about writing a small Leasing Calculator. I had my leasing mathematics library ready, but it was written in C#. I didn’t feel like rewriting it in JavaScript - what for? So Script# was a blast for me. I had my Leasing Calculator gadget in view hours.

What do you need to start working with Script#:

1. download the latest binaries from Script# project page

2. install it

3. create new Visual C# -> Script# -> Sidebar Gadget project in Visual Studio

You will get quite useful project template. The inside of Content folder is your gadget. If you compile everything Script# will transform your C# into JavaScript and place it in this folder. The last thing you have to do is to copy this folder into your Vista Gadgets folder (C:\Users\user\AppData\Local\Microsoft\Windows Sidebar\Gadgets\). You will have to do the same every time you will compile. Surely it is something to automate. The easiest way is to use the Post-build event in your project and a small MSBuild script that will copy the needed files to the place they should by.

$(WinDir)\Microsoft.NET\Framework\v2.0.50727\msbuild.exe $(SolutionDir)build.msbuild

And use this script:

<Project DefaultTargets=“Deploy” xmlns=“http://schemas.microsoft.com/developer/msbuild/2003“>
  <PropertyGroup>
    <DeploymentFolder>YourVistaGadgetFolder.gadget</DeploymentFolder>
  </PropertyGroup>
  <ItemGroup>
    <DeploymentSourceFiles Include=“LeasingCalculatorContent***.*” />
  </ItemGroup>
   <Target Name=“Deploy“>
    <RemoveDir Directories=“$(DeploymentFolder)” ContinueOnError=“false“></RemoveDir>
    <Copy SourceFiles=“@(DeploymentSourceFiles)”
      DestinationFiles=“@(DeploymentSourceFiles->
      ‘$(DeploymentFolder)%(RecursiveDir)%(Filename)%(Extension)’)“/>
   </Target>
</Project>

So you are equipped with fully functional development platform for Vista Sidebar Gadgets.

One more thing. I do think that writing a JavaScript in C# is a good idea ;) but if you are new to Sidebar Gadgets you probably would like to take one step by step tutorial. It would help to understand Gadgets on the low level an d will get you up to speed with Schipr# later.
