Strange exe-naming

[FFF]

Chris,
by chance i had a look into my bindebug folder and found some "strange" files like:
bcc5f20a-a180-4b27-823b-7abf0367d4e6__SQL.exe or
d20e51d5-b630-4f65-bee9-f7ba8612cfd6__TomLibVirt.dll
The "regular" ones are named like: __TomLibVirt.dll
I suspect that may be result of some problems i had, but i'm curious - probably i should simply delete them and forget?

Hi Karl,

I had such files too from time to time and was wondering where they are coming from. Just yesterday I realized they are created when you try to compile an app that is already running, when this happens, the existing dll/exe gets renamed to that strange file name.

Guess that's a feature of roslyn, tried to search about this, but did not find anything. Maybe Robert has further info?

Chris,

Yes this is what Roslyn does: when there is a sharing violation writing the output file then the existing file is renamed and marked for deletionSee:

https://github.com/dotnet/roslyn/blob/master/src/Compilers/Core/Portable/CommandLine/CommonCompiler.CompilerEmitStreamProvider.cs, line 80.

The files should be hidden. I guess Karl has the option to show hidden files enabled.
The files normally should automatically be deleted when they are no longer in use.
