VS bug #818720

The text was updated successfully, but these errors were encountered:

Quick ugly workaround :

Edit your "Xamarin.iOS.Common.targets" file,
Replace the "ditto" part with the below one :

<PropertyGroup>
    <AllResolvedAppExtensionReference>@(_ResolvedAppExtensionReferences)</AllResolvedAppExtensionReference>
    <FirstResolvedAppExtensionReference>$(AllResolvedAppExtensionReference.Split(`;`)[0])</FirstResolvedAppExtensionReference>
</PropertyGroup>
<Ditto
    SessionId="$(BuildSessionId)"
    Condition="'$(IsMacEnabled)' == 'true' And '@(_ResolvedAppExtensionReferences)' != '' And '%(_ResolvedAppExtensionReferences.Identity)' != ''"
    ToolExe="$(DittoExe)"
    ToolPath="$(DittoPath)"
    Source="$(FirstResolvedAppExtensionReference)"
    Destination="$(_AppBundlePath)PlugIns\%(_ResolvedAppExtensionReferences.FileName)%(_ResolvedAppExtensionReferences.Extension)" />

The original snippet was :

<Ditto
    SessionId="$(BuildSessionId)"
    Condition="'$(IsMacEnabled)' == 'true' And '@(_ResolvedAppExtensionReferences)' != '' And '%(_ResolvedAppExtensionReferences.Identity)' != ''"
    ToolExe="$(DittoExe)"
    ToolPath="$(DittoPath)"
    Source="@(_ResolvedAppExtensionReferences)"
    Destination="$(_AppBundlePath)PlugIns\%(_ResolvedAppExtensionReferences.FileName)%(_ResolvedAppExtensionReferences.Extension)" />

It works when I follow your instructions.
Logs: https://gist.github.com/spouliot/b38f53580abd36672ef5f05bb76dd435

OTOH It seems to skip Ditto so it might have something to do with the type of extensions being used. Can you attach your own solution to the issue ? thanks!

so it seems Ditto was called twice - and not with multiple targets.

spouliot · 2019-03-12T14:34:52Z

It also works with current stable and I only see one extension in your logs: MyApp.iOS.NextToSeeExtension.appex
so I'm not sure it's related to multiple extensions.

jonathanantoine · 2019-03-12T14:49:12Z

Here is a repro project @spouliot , you will have to restore nuget packages : CrossTVST.zip

jonathanantoine · 2019-03-12T15:03:55Z

OMG, don't ask me why but you are right, the references where not the right ones :

A manual edit seems to fix it @spouliot

spouliot · 2019-03-12T15:24:04Z

@jstedfast @sgmunn I don't know how it happens (but the SDK don't read, nor modify, .csproj) but it causes issues in builds

spouliot · 2019-03-12T15:27:43Z

test case accessible from https://developercommunity.visualstudio.com/content/problem/459627/watch-app-template-fails-to-build-msb4094-in-vs-ma.html?childToView=478997#comment-478997

jstedfast · 2019-03-12T16:10:12Z

Do we know how this happened? Are there steps that I can perform in the IDE that cause this?

VincentDondain · 2019-03-14T16:11:24Z

I just created a new iOS single view project + new watchOS project with VSMac master and got the issue.

It's indeed the double watchOS reference:

<ProjectReference Include="..\MyWApp.WatchOSExtension\MyWApp.WatchOSExtension.csproj">
      <Name>MyWApp.WatchOSExtension</Name>
      <Project>{501ACAFB-4C16-47DF-BB63-73FF448B53BE}</Project>
      <IsAppExtension>True</IsAppExtension>
    </ProjectReference>
    <ProjectReference Include="..\MyWApp.WatchOSExtension\MyWApp.WatchOSExtension.csproj">
      <IsAppExtension>true</IsAppExtension>
      <Project>{501ACAFB-4C16-47DF-BB63-73FF448B53BE}</Project>
      <Name>MyWApp.WatchOSExtension</Name>
    </ProjectReference>

Likely something wrong with the template or the new project dialog mechanisms.

I bet the IPhoneProject logic is duplicated in the TemplateWizard logic

Hi. I just had the same issue. I had a extension project included in iOS then I had to remove it. Then a few days I had to add the same code again. It was removed from the code base as well. When I re-added the new project I got this error. I looked at my git history and the thing is that the IDE did not remove the reference from my csproj file at the time I removed the extension project. My git history says this. So when I re-added the extension project it just added another entry to the iOS csproj file.

This post saved me. Thanks!

... as a note to people that still have problems with the "Ditto" after they have removed the dublicate entry and the code compiles but get this error deploying to a real iOS device: Restart IDE. That did the trick. I'm on VS for Mac.

restorepro · 2022-01-15T03:59:48Z

I had the same problem and I spent several hours trying to figure out what it was! I had 2 identical "Project References" in my Xamarin ios .csproj file. Open that file up using the VS for Mac editor (right click the .csproj file and it should be the top-most option) and open it and search for Project Reference. If there are identical entries, comment out one of them and save the changes.
