FYI - the tests work when running them from terminal.

@haridasnykiel I am unable to reproduce the problem on my machine. Here is the sample project that I used: https://github.com/akshita31/xunit-2.3.1 and the "Debug test" seems to work fine for me for
VS Code version: 1.26.1
C# Extension version: 1.15.2

Could you share your project so it would be easier to debug what might be the error for you ?

[haridasnykiel]

https://github.com/haridasnykiel/Design_Patterns
this is the project that has caused this issue. I have tryed to create another project with the same configuration and this issue is still occurring. Seems to be a config with my vs code.

[DustinCampbell]

I cleaned up the exception text so that it is clearer to see what is failing. It seems that the result of dotnet --version was not parseable by OmniSharp? That's very strange. Could you cd to the directory of the test project with the terminal window, run dotnet --version, and let us know what the output is?

[haridasnykiel]

It is really strange because it was working and then it just started to throw this error without me changing any configurations or updating any packages. Anyway this is the output of the dotnet --version command: 2.1.302
Thanks your help

[haridasnykiel]

I am also getting the following issue when I start a vs code instance. I have now updated to SDK version: 2.1.402 Would really appreciated is this could looked into. I cannot use my debugger at the moment. Here is my output when run the command echo $PATH: /Library/Frameworks/Mono.framework/Versions/Current/bin/:/Users/Hari/.rbenv/shims:/Users/Hari/.rbenv/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/share/dotnet

Also I should mention that I am able to build and run my project from the command line but just not from the VS code GUI and it seems like my debugger is not working due to this issue.

@haridasnykiel if you open the terminal window in VS Code and run dotnet --info what do you get? Also, what shell are you using?

VS Code has some code to attempt to launch your default terminal and scrape the PATH environment variable from it. My guess is that this is not working on your computer for some reason.

It shouldn't matter what your project is for this particular error.

[haridasnykiel]

This is the output of the dotnet --info command.

[gregg-miskelly]

To be clear - @haridasnykiel that is the output you get from the built in VS Code terminal (NOT a normal terminal window)?

I have having trouble finding the code in VS Code for this, but the way VS Code tries to workout PATH is by running your shell and having it spit back the value of $PATH. This problem happens when you have something in your shell setup scripts (.bash_profile, .bashrc) that breaks this.

[haridasnykiel]

I did not realise there was a difference between the two, in terms of the output when running that command. But by looking at the output from the terminal (not vs code built in terminal) the output looks the same to me:

As you can see it is exactly the same.

I have tried uninstalling and reinstalling vs code and the c# extension.
I have also deleted and reinstalled the SDK.

I have also noticed that I am getting the folloeing in the output:

Failed to spawn 'dotnet --info'

[haridasnykiel]

Hi, Any update on this issue I am experiencing?

[haridasnykiel]

I resolved this by uninstalling oh my zsh shell.
