Description softlion 2017-10-12 09:27:56 UTC
This project was building fine until i updated to VS 15.4.

Reproduce:
- clean solution
- build/run project => ok
- build/run project => sharing violation
- build/run project => sharing violation
- build/run project => sharing violation
- build/run project => sharing violation
- build/run project => sharing violation


Build log when that happens (every time after first build):

Comment 1 Rolf Bjarne Kvinge [MSFT] 2017-10-13 13:44:43 UTC
Can you check if the file is readonly by executing the following command from a terminal and attaching the output (after getting the error once)?

Comment 3 softlion 2017-10-16 08:24:24 UTC
Same error on another project.

Seems an issue with System.Threading.Tasks.Dataflow nuget (version 4.8.0).
When the nuget is added to an ios project, every incremental compilation fails.

Comment 4 Rolf Bjarne Kvinge [MSFT] 2017-10-16 17:14:52 UTC
I tried adding the System.Threading.Tasks.Dataflow nuget to a test project, but I couldn't reproduce any problems.

Can you reproduce the problem if you use Visual Studio for Mac?

I can fix it blindly, but I'd like to be able to reproduce it so that I can understand fully what's going wrong.
Comment 5 softlion 2017-10-16 17:54:49 UTC
Yes.
I just get it using vs for mac.

I happens when compiling a xamarin.ios project referencing a netstandard 2 library in which is added and used (important!) the DataFlow package. 

Build failed again the second time the project is built:

Comment 6 Rolf Bjarne Kvinge [MSFT] 2017-10-16 18:07:48 UTC
Can you add "-f" to the additional mtouch arguments in the project's iOS Build options and see if that works around it?

That will cause everything to be rebuilt every time, and might work around the issue.
Comment 7 softlion 2017-10-16 18:13:33 UTC
It works ty, but is slow to build now :(
Comment 8 Rolf Bjarne Kvinge [MSFT] 2017-10-17 09:25:30 UTC
It's slow, but it's still progress :)

I've tried to reproduce this with the information from the build logs, but I'm not having much luck.

Would it be possible to get access to your projects? If not, please add "-v -v -v -v" to the additional mtouch arguments, rebuild, and attach the complete build logs for both a working and broken build.
Comment 9 softlion 2017-10-18 08:46:57 UTC
I can not reproduce the problem on another project using the same nuget package. This is strange.
Comment 10 Alex Soto [MSFT] 2017-11-21 23:28:58 UTC
@Softilon is this still an issue? If so are you able to provide the requested info in comment #8

Thanks!
Comment 11 softlion 2017-11-22 08:09:15 UTC
No it seems to be fine now
Comment 12 Alex Soto [MSFT] 2017-11-22 15:58:31 UTC
Thanks, closing this then, feel free to reopen if needed.
Comment 13 Rolf Bjarne Kvinge [MSFT] 2018-01-10 06:51:01 UTC
