Hello! Problem with application coded on C# using >=.NET 4.0 .

listener.Prefixes.Add("http://localhost:1234/listener/");
listener.Start();

you do not give a link to the application - do you have a test application that shows the same behaviour? ideally with source code

worked for me under wine 5.0.1 installed in ubuntu 20.10
Application compiled under Visual Studio Community 2017, against .NET 4.6.1
Tested from local browser using http://localhost:1234/conn
Did you use built-in winemono?

Code: Select all

wine ConsoleApplication1.exe 
0009:fixme:mscoree:parse_supported_runtime sku=L".NETFramework,Version=v4.6.1" not implemented
0009:fixme:mscoree:parse_supported_runtime sku=L".NETFramework,Version=v4.6.1" not implemented
Wait for connections...
Bye!
0037:fixme:console:CONSOLE_DefaultHandler Terminating process 8 on event 0
0037:err:mscoree:expect_no_runtimes Process exited with a Mono runtime loaded.

Hi edx,
I would try to debug .NET app and try to convert it to be compatble with winemono - eventually this will allow you to be cross-platform.
e.g. try to use FreeTDS client to access MS SQL and other simialr approaches. I had some experience on it and I think this is feasible.
You can debug it by installing mono on windows, and developing there, and then when it succeeds proceed with testing with winemono.
You can contact me and I can share my experience.
As a succesful cross-platform example - I can suggest fastreport.mono - https://www.fast-report.com/en/blog/232/show/
