Don't do Shell Extension Handlers in .NET

Thank you Junfeng,

this is very interesting. Does this problem apply to COM Addins, too? I wrote a lot of COM Addins (for Microsoft Project and Outlook).
Some of them are managed, some unmanaged. Should I worry that the managed dlls will have problems with future versions of .Net (as I can't control other Addins the user might have installed I can't control the framework version) ? What if I plan to upgrade the Addins to 2.0 myself? Will any 1.1 Addin that could get loaded before break my addin?

Thank you in advance

The lastest CLR will be loaded for COM addins. So if you believe CLR's compatibility story you should be covered.

The shell extension is a little different, because it is bleed to other applications (like the file open dialog example above). If the COM addin does not bleed to other processes, it should be fine.

Good to hear so our Addins will work for quite some time hopefully. Is it to be expected that 1.1 programs will still work in a .Net 3.0 / 4.0 runtime? I know this might be difficult to answer but your "believing the compatibility story" sounded a little skeptical...

I will expect v1.1 applications will work on any future version of .Net, as far as CLR is concern.

But I can't guarantee anything on the libraries you depend on.
