Environment data

dotnet --info output:
VS Code version: 1.7.1
C# Extension version: v.1.5.0-beta7
.NET Core version: 1.0.0-SDK Preview4
OS: Win7x64

Steps to reproduce

1. Launch the project in Command Prompt(cmd window) using the Command 'dotnet run'.
2. Open the attachment project with VSCode.
   hwapp.zip
3. Set a bp at line of 12 in Program.cs.
4. Select the debug type '.Net core Attach'
   
5. Press F5 to start debugging

Expected behavior

Pop up the UI that we can select the process to start attach.
like the picture:

Actual behavior

The UI window didn't display, and pop up an error message.

Investigation:

1. I tried to change attch configurations in launch.json file
   "processId": "4312"
   press F5 again, and the bp can be hit. Attach can work correctly.

I think the issue here is that the process listing code is broken on Win7.

@ClaireKang I did a quick test on Windows 7 with the following and attach seems to work fine.
VSCode: v1.7.1
dotnet cli: 1.0.0-preview2-003133
OS: Win7x64
C# Extension version: v.1.5.0-beta7

Perhaps it is a unintended consequence of using ".NET Core version: 1.0.0-SDK Preview4", can you try installing Preview2 and try it again?
Would you also mind just running "wmic process get Name,ProcessId,CommandLine /FORMAT:list" on a cmd prompt in your Windows installation?

I tried do the test with 1.0.0-preview2-003133, Attach can work correctly.

Closing this issue. Lets revisit this when testing preview3 & preview4.
