Control EA via command line

The App object represents a running instance of Enterprise Architect. Its object provides access to the Automation Interface.

The equivalent in C# would call Marshal.GetActiveObject

Ok, but that is to connect to an already running instance isn't it?
I think Jörg wants to start a new instance of EA.

The code I copied came directly from the manual in the section C#. Is that not correct?

Thanks for the replies.

@Eve: I also tried this approach just for test, but the call to Marshal.GetActiveObject("EA.App") returned null. And yes, EA was running befor calling  .

@ Geert: I've found this article while searching a solution, too. Unfortunately it doesn't work  as described in my question.

There seems to be something wrong with the types. I have no clue why this happens and how to fix that. I tried the code in several VS-Projects, with different .NET Framework versions and .NET Core 3. Always the same result.

Is there no idea how to solve this?

In my Project I use .NET Framework 4.7.2 but I also tried it with .NET 5.0 and .NET Core 3.1 -> no success. According to the EA documentation it should be possible.

I need this for module testing of modules that need data from EA Repository (modules of an EA-AddIn). If someone has ideas how to test EA-AddIn modules in another way, I'm open to hear them.

You could use the Labnaf PowerShell (https://www.labnaf.one/EndUserMaterial/Labnaf_PowerShell/Labnaf%20PowerShell%20-%20User%20Guide.pdf)

The following features are independent of the modeling language:
 Schedule Command (not only Labnaf PowerShell commands)
 Generate Word, RTF, PDF (there are also templates provided)
 Generate Html (with ability to start email discussion from any diagram on the generated web site)
 Backup To Access File

The following features are designed for the unified Labnaf language
(unified language for driving transformations: https://www.labnaf.one/guidance/index.html?guid=D1744801-D8E6-4715-83DB-DED6C781B191):
 Generate Tabular Report (sophisticated Excel, CSV) from modeled templates
 Import Tabular Report (Excel, CSV)
 Cascaded Value calculation
 Validate and send emails to assigned individuals following configurable rules
 Generate Diagrams from diagram templates
 Generate implicit connectors
