Debugger does not work if add a breakpoint

[svor]

I tried to use netcoredbg with dotnet 2.2.104.
If I don't set breakpoints everything works fine, but if I add one or more breakpoint I'll get an error:

{ 
	command: 'threads',
  	message: 'Failed command \'threads\' : 0x80004005',
  	request_seq: 4,
  	seq: 6,
  	success: false,
  	type: 'response' 
}

Environment

• os: Fedora 28 Twenty Eight (x86-64)
• dotnetcore-sdk: 2.2.104
• netcoredbg: latest releas

Logs

netcoredbg's log file is here: https://raw.githubusercontent.com/svor/files/master/netcodedbg-launch.log

Hello @svor, thank you for reporting this issue.

It looks like your IDE did not send the configurationDone command. This command actually launches the process. Since there is no process the threads command fails.

netcoredbg's error messages surely need an improvement 😄

@ayuckhulk Thank you! I found the problem on my side and your information helped me)
Actually the problem was that I expected debug capabilities in initialize response, but it comes after capabilities event and the value of capabilities was overwritten.

Good catch @svor . I think the current approach of not returning capabilities in initialize is an anti-pattern and doesn't fit very well in specification recommendation. I've open #14 to get it improved in netcoredbg.
