Also error popup with text: "An error during installation of the .NET Core Debugger. The C# extension may need to be reinstalled.

Since it never got to "Done!" for the debugger, I'm guessing the zip file was partially downloaded and corrupted. What's bizarre is that is that it stopped twice for the debugger. @psoszynski: If I understand you. the same thing has happened with multiple versions of the extension, correct?

Any ideas @gregg-miskelly?

[psoszynski]

Yes, it happens with multiple versions. I also tried removing the C# extension from VSCode and installing it again but it doesn't help.

What is weird here is the Platform reported by the tool: win32, x86_64 (win7-x64) is not the same as win10-x64 which is the actual platform as shown at Product information part a little higher up.

Yesterday, I had the same issue on a different instance of Windows 10 (also VirtualBox).

Re: win7-x64 is expected. This isn't necessarily the RID for your OS, it's the RID we're using to piack a download. win7-x64 is fully compatible with win10-x64

[psoszynski]

I have reinstalled .NET Core Preview3, this time with bits from this location (instead of these that came with Visual Studio 2017 RC, as before): https://github.com/dotnet/core/blob/master/release-notes/preview3-download.md

Unfortunately, it is still not working, although the message in output is a little shorter now:

I am suspecting that this can have something to do with the fact that I execute this in a Virtual Machine (VirtualBox). When I repeat the same steps on my Windows 7 laptop all works perfectly.

[gregg-miskelly]

@psoszynski: on the computer from the first output (the x64 computer), does the C# extension try to download the debugger every time you start VS code and open a C# file or do we only try once (per install of the extension)? Does it take a long time to fail the first time (before the 'retrying from...' line gets printed)? If you try downloading the file in a web browser do you have any better luck?

For your second output (x86 computer) - the failing to install the debugger package is expected, though maybe we should do a better job with the messaging there - looks like this is an x86 Windows box, and the debugger doesn't yet support x86 Windows (#844).

[psoszynski]

@gregg-miskelly yes, on the x64 virtual machine the c# extension tries to download the debugger every time I start VS code and open a C# file. It doesn't take that long, about 15 seconds.

Well, I tried now 3 times and on the 3 attempt it succeeded! Here is the output:

On the previous attempt, that failed, the message was also different then previous ones but I did not copy it and do not remember it exactly.

[psoszynski]

@gregg-miskelly Just a short extra question, is it normal that my breakpoints do not get hit? The compilation and output looks ok.

[gregg-miskelly]

@psoszynski are there any warnings printed to the debug console?

[psoszynski]

@gregg-miskelly I startet a new clean project and the breakpoints are now hit. Thanks for your help and keep up the good work.
