And a thorough description of the problem / question:

I got some analyzer exceptions when I had some invalid c# code, this was the offending code (new ASP.NET Core 9 Aspire project with space in the projectname. That seems not to be supported that well.)



var builder = DistributedApplication.CreateBuilder(args);

builder.AddProject<Projects.Data Protection Demo>("data protection demo");

builder.AddProject<Projects.Data Protection Demo2>("data protection demo2");

builder.Build().Run();

Hello @tn-dev and thank you for reporting this.

I cannot unfortunately reproduce it.

The code you provided is the only piece of code in the file?
Would be great if you could provide me with a full repro project or the full file.

Thanks a lot!

Hi

You can download a sample project from

https://www.dropbox.com/scl/fi/zp5vwa227zvoy2ezp7cea/Test-Web-Application-Sonar.zip?rlkey=of9whe9akx850ci4l1mjx9rua&dl=0

basically

I create

Both projects are enlisted in Aspire. I have not modified any of the projects.

Yes, the code does not compile, and I get the sonar exceptions.

Guess its triggerd by the invalid code here due to the space in the project names.

Thanks @tn-dev !

Unfortunately for security reasons I cannot pick this project up from dropbox.
Could you please share it via github or I could send you a private message and you can attach it there.

Thanks!

Send a email and I will reply with the attachment file.

Hello Tore,

the issues disappear once there’s no compilation error?

do you have any particular configuration in your environment - how you build the projects etc?
