Serial Port 2.0 to 1.1 backward compatibility

[Dominick ODierno]

If I write a program, say in C#, to read and write to a serial port and use the SerialPort class in .NET 2.0, will this program be compatible with machines still using .NET framework 1.1?

[Dan Neely]

No. To use any 2.0 classes you need the 2.0 framework.

[Dominick ODierno]

So if I developed it on a machine using .NET 2.0, compiled it, and moved the EXE to a computer with .NET 1.1, it would fail?

[Dan Neely]

Yes.

[Dominick ODierno]

ok, good to know, thank you.

I think the serial port classes were new in 2.0 so they wouldn't even be in 1.1.

[Dan Neely]

They aren't. MS published a net1.1 beta version of them on a code site with a non commercial use only license, but otherwise you can't use them without .net 2.0.
