Using EA in ASP.NET Core 2.1

[Slávek Rydval]

I want to create ASP.NET Core 2.1 application with reading data from EA (I know that joining .NET Core with the Win32 world is not recommended). I create a web application from the template in Visual Studio 2017, add a reference to Interop.EA and in a controller is this code:

Code: [Select]

public IActionResult Index()
{
    EA.Repository r = new EA.Repository();
    r.OpenFile(@"c:\Temp\UCI.EAP");

    return View();
}

When creating a new instance, it fails with System.ExecutionEngineException exception (in data of the exception is {System.Collections.EmptyReadOnlyDictionaryInternal}). Do you have any idea how to fix it?

An instance of EA is in processes created.

I don't have a solution to your problem, but want to point out that using the EA API from an ASP application would require a license of EA for each end user of that application. (To conform with the license agreement. See section 6)

Simon, cheers for the message, I know it. Fortunately, we've got enough licences.

To be more specific after a couple of hours spent with it:

• the exception is thrown on .NET Core 2.0, 2.1 and 2.2
• on NET Core 3.0 Preview 1 it is working correctly.

The thing is that 3.0 is still a preview, so the solution is still missing.

Sounds like you are trying to expose some Sparx EA things via a web interface.
Do you know there is a product called WebEA and Cloud Pro Server that does this?
Using Sparx EA application on a web server doesn't sound like a good idea by the way.

Yes, I know it. WebEA doesn't solve my needs no matter what they are.
