VSO GitVersion breaks MSBuild

[justdeserves]

The latest release of the vNext GitVersion task causes an error during the MSBuild process. Error CS0579: Duplicate 'AssemblyVersion' attribute & Error CS0579: Duplicate 'AssemblyVersion' attribute.

On removing the task from the build pipeline the code successfully compiles. I have not selected the option to 'Update AssemblyInfo files'

Is there a work around?

I think this is related to #714 as @csmager had a similar issue.

Can you grab the versions at https://ci.appveyor.com/project/GitTools/gitversion/build/3.5.1-AssemblyInfoFix.1+1.build.673/artifacts and see if this is still a problem.

I reverted the above PR to see if it helps. Am heading to bed now so would be great if you could test and get back to me. If that works I will release a patch tomorrow morning

Maybe this is related to #846 (In the current version the "Update AssemblyInfo files" option doesn't make a difference, the files always will be updated)

[JakeGinnivan]

There are two issues here, the fact that the checkbox doesn't work means you cannot work around the other breaking change.

@justdeserves if you are able to check that branch I linked above (use the command line to check) and see if it fixes the underlying issue too.

@JakeGinnivan I implemented the fix above this morning , but came across this:

[JakeGinnivan]

@justdeserves that should be fixed, how are you building/running GitVersion.exe?

[justdeserves]

@JakeGinnivan I'm using the GitVersion.exe that is bundled in with the
GitVersionTfsBuildTask_3.5.1-assemblyinfofix0001.zip

[JakeGinnivan]

Ah, that is broken for that branch.

Use the GitVersion.exe in https://ci.appveyor.com/api/buildjobs/b6io43o3wx1vntf9/artifacts/GitVersion_3.5.1-assemblyinfofix0001.zip

3.5.0 build vnext was broken =(

[justdeserves]

I've run through a few builds - it appears to be sorted and not raising the problem anymore. Ty for your assistant.

[JakeGinnivan]

Ok sweet, will close
