Use executable results in EventPipe error #173

Open flcdrg opened 4 years ago

flcdrg commented 4 years ago

Describe the bug

If I use executable instead of project then a debug error is logged that the event pipe session start failed. If I use project pointing at the same project (instead of the exe) then it runs without the debug error

To Reproduce

  1. Edit the single-project tye.yaml file to contain the following 
    
# tye application configuration file
# read all about it at https://github.com/dotnet/tye
name: single-project
services:
C:\dev\github\tye\artifacts\bin\tye\Debug\netcoreapp3.1\tye.exe run

Here's a question - do you want to be able to collect eventpipe/metrics for arbitrary .NET executables?

We should definitely fix this error. The question is relevant, because eventpipe is available in any .NET process >= 3.0. So presumably if there are random executables you want to run, and they are .NET - then we can also collect their metrics.
