One of our projects fails to build with: "csc.exe" exited with code -2146232797 #33542

I don't have any idea why this would happen, this used to build on everything except Visual Studio 2019 Preview 2, preview 1.1 worked.

This issue has been moved from https://developercommunity.visualstudio.com/content/problem/434543/one-of-our-projects-fails-to-build-with-cscexe-exi.html VSTS ticketId: 776735 These are the original issue comments:

Still does this in preview 2.1. It hangs for a very long time and then doesn't build.

@jaredpar I believe this is COR_E_FAILFAST

Looks like this builds in dev15 but not dev16.

I'm getting this with a dot.net core 2.2 (SDK 105) project. Just yesterday it started failing in both the latest version of VS.net 2017 and the RTM of 2019 if it matters.

building the solution from the command prompt with dotnet build works fine.

jaredpar commented 5 years ago

@JohnGalt1717 is there some source you could share out that would help us understand if this is related to other issues we're looking into?

JohnGalt1717 commented 5 years ago

@jaredpar Unfortunately not. One project doesn't work, the other does.

There appears to be something really wonky going on with .NET core 2.2. sdks though. VS.net 2019 installs 2.2.202 but the most recent listed on dot.net is 2.2.105 which makes no sense at all and I think is part of the problem.

Using 2.2.105 in our global.json file using FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build in our docker results in the following error now as well which doesn't happen at command prompt in windows:

And the error happens with or without the langversion and nullable referencetypes option. I suspect it's one of the nguet dependencies but not sure which.

And it is now doing it with dotnet build

@JohnGalt1717 thanks the stack trace help. Pretty sure that is a separate issue. Asked @cston to take a look at it.

pkindruk commented 5 years ago

@jaredpar same problem here, but completely different environment. @JohnGalt1717 new roslyn compiler seems to be the case for my problem. What version do you fail with? And try finding code pattern methioned in this issue.

Then I opened my sandbox console app (.NET Framework 4.6.1) and used code issue starter provided. Same result. I went to the project originally failing and found code like this(I omitted all business logic):

class A
{
    private async Task DoSmth()
    {
        try
        {
            try
            {
                //1
                return;
            }
            finally
            {
                //2
                await Task.CompletedTask;
            }
        }
        catch { }
        finally
        {
            //3
            await Task.CompletedTask;
        }
    }
}

Removing any of numbered lines makes code compile.

My primary project is still compiling with vs2017. So I put that simplified class above in the console app right next to plain Main method and tried to compile on vs2017 (success) and vs2019 (failure). All projects were created under vs2017 and opened in vs2019 if that matters.

And last thing csc.exe versions:

c:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin\Roslyn>csc -version
2.10.0.0 (b9fb1610)

c:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Current\Bin\Roslyn>csc -version
3.0.19.17001 (1deafee3)

Hello. I also see that issue. It compiles fine in VS 2017 and not in VS 2019.

This is our solution: https://github.com/thinktecture/relayserver/tree/2.2.0 In the project OnPremiseConnector in the class RelayServerConnection we have a try -> try -> finally -> await constellation that might be another version of #34720.

This issue is blocking updating to VS 2019.

cston commented 5 years ago

@gingters, #34791 should fix the code gen issue with an await in a nested finally clause. In the meantime, before the fix is available, are you able to get unblocked by extracting the nested try/finally to a separate method or local function?

Starting with VS2019 PREVIEW 16.3.0 Preview X (1..4) I get this exact message for one (large!) project in a solution containing 132 projects. It's the second-important project in this solution :(

Using VS2019 RELEASE 16.2.X everything is ok. I fear when 16.3 will become the new release this bug still will be present. What can I do to narrow this problem down?

C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\MSBuild\Current\Bin\Roslyn\Microsoft.CSharp.Core.targets(59,5): error MSB6006: "csc.exe" exited with code -2146232797.

@springy76, thanks for reporting the latest issue. Is there a stack trace for the failure in csc.exe in the Windows event log? If so, please share the stack trace if you're comfortable doing so. Thanks.

springy76 commented 5 years ago

@cston I found the event log later and then created a new issue #38725
