It\'d be really nice to target my Windows Forms app to the .NET 3.5 SP1 client framework. But, right now I\'m using the HttpUtility.HtmlDecode and
Apparently google couldn't find it either, so they wrote there own api-compatible version:
Here's a workaround:
Compile Google's version as a library
wget 'http://google-gdata.googlecode.com/svn/trunk/clients/cs/src/core/HttpUtility.cs'
gmcs -t:library HttpUtility.cs
Edit your-project.cs to include that namespace
using Google.GData.Client; // where HttpUtility lives
Recompile using the library
gmcs your-project.cs -r:System.Web.Services -r:System.Web -r:HttpUtility
From glancing at the source code, it appears that this is .NET 2.0-compatible.
I just wrote my first hello world in csharp yesterday and I ran into this problem, so I hope this helps someone else.
