AssemblyInfo patching not working for one project in a solution

I'm using the AssemblyPatching feature for a set of NuGet packages on this project but one of the projects (JamesDibble.Extensions.System) does not have its version information updated. I have tried recreating the project several times and diffed it with the projects that are working but it hasn't made a difference. Is there anything specific that would prevent this from happening? It wouldn't be a massive problem but it is preventing automatic deployment to NuGet as the package versions are the same.

    Is there a standard AssemblyInfo.cs? Could you paste it's contents please?

    It should be. It came from the standard C# library project. Here's the file

    Hi James,

    I'm trying to reproduce the issue and that Assemblyinfo.cs is getting patched:

    Hey, and thanks for writing about AppVeyor in your blog! ;)

    Ok, this a bit odd then. If you take the (Nuget package)[] from the latest build, extract it and check the AssmbleyFileInfo version it says in it still, which is why the Nuget package gets version accordingly. I had an AppVeyor project on the same repository with identical settings that worked as expected ONCE, then reverted back to putting even though no changes had been made to either the .csproj, AssemblyInfo.cs, .nuspec before it worked, on the build it worked, or the subsequent build it stopped working again.

    Is this a side affect in another part of the build somehow and like your demonstration project shows, the AssemblyInfo is being patched but not being adhered to when it hits MsBuild?

    What was the script you ran in your demonstration and could I run it on my project to check we're getting the same results?

    And no problem, thanks for reading :)

    Well, I enabled assembly patching through UI, no appveyor.yml there. Will do that with appveyor.yml and let you know about the results.

    I get same the same (result)[] which is ALWAYS good.

    It must be the NuGet packaging as you say. Any suggestions looking at the (.nusepc file)[]? It's about as basic as they get and all the other packages in the solution using a very similar format work fine.

    I think the problem is that $version$ variable is getting expanded when you package VS project like nuget something.csproj (this case nuget knows the assembly to extract version from). If you do package nuget my.nuspec then $version$ variable should be provided by you.

    We were right about it being the NuGet packaging, but not for any good reason!

    Some of the other .csproj files were dependent on the Extenstions.System dll so in one of my weirder moments I must have decided to use NuGet to get the dependency rather that use the local project. Coincidentally, this made the solution download a REALLY old version of the dll from NuGet and put it in the output directory which was then picked up when trying to build the new NuGet package for the same dll, hence why the assemblyinfo patching was working fine, but the artefacts being build had totally different versions.

    Everything working great now. User error!

    Thanks for all your help.
