Visual Studio 2017 - "The request is not supported"

[petar-maletic]

ConEmu build: 180206 x64, 180206 x64, 161206 x64
OS version: Windows 7 x64

Problem description:
I've installed ConEmu (tried all versions above). Options "Force ConEmu as default..." and "Register in OS startup" are enabled, also I've added devenv.exe to hooked executables list. Everything is working fine with Visual Studio 2013, both start with debugging and without debugging... but with Visual Studio 2017 I'm getting error message "The request is not supported" when trying to start my console app with debugging.

Is there a way to setup VS 2017 / ConEmu to work with start with debugging option?
Thank you.

It works properly on my Win 10 (1709), VS 2017 (15.5.x) and ConEmu 180318.

Not enough info to go further. At least I need exact message text and Log Files.

Getting the same issue here, on Win 10 (16299), VS 2017 (15.6.5) and ConEmu (180409), UAC enabled.

This is the error I'm getting from VS:

And the logs from ConEmu (debug hooked process)
devenv.exe-26500.log

Works fine when starting without debugging, but fails with debug.

• What project type do you try to debug? C#, C++, Desktop, UWP?
• What platform and config? Mixed/x86/x64/release/debug?

[jValdron]

C# console application on Debug/Any CPU.

@jValdron Log file devenv.exe-26500.log was created during Debug attempt or "run without debug"?

[jValdron]

devenv.exe-26500.log was created during the debug attempt. Here's of a successful run without debug, then an attempt at debug. There is extra stuff at the beginning, looks like it grabbed the execution of grunt too.

devenv.exe-33172.log

So, the project was being built with Any CPU, but it had the "prefer 32-bit" option enabled. Removing this (or building for x64 directly) launches the console application just fine, however, it is not being captured by ConEmu.

So in short, launching 32-bit returns "The request is not supported", x64 is fine, but not being captured by ConEmu.

@Maximus5, looks like 653a651 did the trick. Running in preview, at v18.04.15 at the moment, and debugged my solution when it popped up in ConEmu.

Thanks for the quick turn around! Having ConEmu handle my console applications instead of having them all loose over the place will be great.

@Maximus5, I see this error in 180506 on 32-bit builds (on 64-bit everything works, including capturing)
devenv.exe-16840.log

[Maximus5]

Sample project or at least exact project/debug options would help

Also, I'm using cmder. Here is my setup if it can help:

@Maximus5 it's been a while now, do you still need repositories from my last comment to resolve this issue?

[Maximus5]

Unfortunately I had not enough time to dig it. Anyway, I forked your repo...

The error went away after setting - compatibility mode.

You need to check "Use Managed Compatibility Mode" in Tools|Options|Debugging|General.
