Internal property in database class fails with surprising exception

[Mackiovello]

using Starcounter;

namespace StarcounterApplication26
{
    [Database]
    public class Person
    {
        internal string Name { get; set; }
    }
    class Program
    {
        static void Main()
        {

        }
    }
}

Throws on start:

The debugging sequence failed with an unexpected error. Consult the Visual Studio activity log for additional information. Error summary: Either body string, body bytes, body stream or resource can be set for Response. (ScErrDebugSequenceFailUnexpect (SCERR12016))

I expected ScErrNonPublicFieldNotExposed (SCERR4285)

Starcounter 2.4.0.5815

Looks like there is some problem when error message is marshaled from tooling -> VS. Do you see a ScErrNonPublicFieldNotExposed in the log at least?

[Mackiovello]

Yea, these are in the log:

OK, then my assumption was right. Something is buggy in marshaling errors between processes then.

I guess I need to schedule this to fix it, but unsure how to prio. @miyconst, you decide please 😄

@miyconst, you decide please 😄

Sure, feel free to ignore the issue for now.

Closing as won't fix in Starcounter 2.4 and not applicable in Starcounter 3.0.
