I recommend that WTVP.NET is only installed on a system where Microsoft Visual C# 2005 and Watch TV Pro 2.24 or later - I tested with 2.21, 2.22 and 2.24 - are installed. This version does not include any support for older Microsoft Visual C# releases.
Please keep in mind that a plug-in developed with WTVP.NET requires the client to have at least the .NET framework 2.0 installed.
Well - that's it! Installing Visual C# 2005 and Watch TV Pro on a system has some implications on the operating system and so on which I will not repeat here. I hope that nothing of the WTVP.NET framework code accesses stuff not available on Windows 9x or so - to be sure someone has to try!
