Firebird(Client) with Silverlight
I tried build FirebirdClient in Silverlight environment and I failed. I expected to fail after some attempts with modifications and using only subset of features like i.e for Compact Framework, but this was really fast. Silverlight is only subset of .NET Framework. And one crucial part is not there, it’s System.Data stuff and without it you can drop major part of any ADO.NET provider’s code.
