Visual Studio 2003 error: This is not a valid assembly or COM component.

Question

I am trying to add FTP client features to my existing application, using Visual Studio 2003. I cannot add a reference to edtFTPnet.dll. I get an error "This is not a valid assembly or COM component. Only assemblies with extension '.dll' and COM components can be referenced. [...]"

Can anyone help?

Thanks!

Craig

Possibly, this is because the DLL has been compiled against a later version of the .NET framework.

You could try rebuilding the DLL using VS 2003.

I try to open "src/edtFTPnet.csproj" with Visual Studio 2003, but I get an error "Unable to read the project file [...]. The project file is missing the VisualStudioProject section."

2003 is ancient, so yes, the project file won't be compatible. You'll need to create another.
