Support for .Net 1.1?

[Stuart Trotter]

Hi All,

I've been writing a few add-ins recently which are compiled in .Net 3.5 and they work perfectly. The problem I have is that a client really wants a few add-ins in .Net 1.1 for EA 7.5. I didn't think this would be a problem until I created a new project in VS2003 and tried to add the Interop.EA.dll as a reference. Visual Studio refused to add it complaining that it's not a valid COM dll. I also tried compiling the standard .Net 1 sample plugin from Sparx and got a compilation error saying the following:

Metadata file 'c:\Program Files\Sparx Systems\EA\Interop.EA.dll' could not be opened -- 'Version 2.0 is not a compatible version.'

Has support for .Net 1.1 been deprecated in EA 7.5? Or am I doing something stupid?

Thanks,
Stuart

Can't you use the (pre .net) com object?
(I think you then need to reference the EA.tbl)

Possibly, but I thought if I used that I can only write automation applications rather than an actual addin for EA... I could well be wrong though.

You should be able to create a version of Interop.EA.dll for VS 2003 and .net 1.1.  Two common ways to do this would be to reference EA.tlb in VS 2003 - this will automatically create the rcw layer or run tlbimp.exe from a command line passing it EA.tlb as a parameter.  This will create a version of Interop.EA.dll which you can use instead of the one provided by Sparx.  You'll need to use the tlbimp.exe version that shipped with VS 2003.  Below is a link to the msdn site that provides the options for tlbimp  http://msdn.microsoft.com/en-us/library/tt0cf3sx(VS.71).aspx .

I don't believe that matters at all.
All you need to do to make your application an EA addin is create a COM compatible dll (and register it), implement the EA methods and let EA know it has to load your dll as an addin via the registry.

Thanks guys, I'll give it try. By implication though I'm guessing that means the standard interop.ea.dll provided by Sparx is for .Net 2 and up.

Thanks again,
Stuart
