Hi everybody,

I am trying to upgrade one of my plugins from 2019 to 2022.

I have adjusted all references and the output path.

Alas, on building the plugin, I receive this error:

Unexpected error at CreatePluginManifestTask-Task.
System.MissingMethodException: Method not found: "System.Collections.Generic.List`1<System.String> Sdl.Core.PluginFramework.PackageSupport.PackageManifest.get_ErrorMessages()".
at Sdl.Core.PluginFramework.Build.PluginPackageCreator.CreatePluginPackage(String fullAssemblyFilePath, String projectDirectory, PluginAssemblyInfo assemblyInfo, IEnumerable`1 referenceCopyLocalPaths, IEnumerable`1 referenceSatellitePaths, IEnumerable`1 generatedFiles)
at Sdl.Core.PluginFramework.Build.CreatePluginManifestTask.GeneratePluginPackage(PluginAssemblyInfo assemblyInfo, IEnumerable`1 generatedFiles)

at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute()
at Microsoft.Build.BackEnd.TaskBuilder.<ExecuteInstantiatedTask>d__26.MoveNext()

I assume other people have already encountered something similar and can tell me, what I am missing / forgot to do?

Thanks!

Best regards,
Andreas
