I've seen an earlier thread discussing the same error, one suggesting that the absence of a model descriptor folder can be an issue, and the apparent MS issue thread, but I don't think I'm encountering either of the first two, so hope someone could please offer guidance. Example of models that can't be found: (1) "ApplicationSuite.VAR Model" (2) "ApplicationFoundation.VAR Model".
Having gone through the AX 2012 > D365 code upgrade & configured my mappings, I'm at the point of attempting to load the CodeMergeSolution or UpgradedSolution VS projects from the Relase folder created in Azure DevOps. When I get latest on the Metadata folder, the Visual Studio output window shows that it's getting objects such as AosService\PackagesLocalDirectory\ApplicationFoundation\ApplicationFoundation.VAR Model\AxTable\Delta\PrintMgmtReportFormat.xml or AOSService\PackagesLocalDirectory\ApplicationSuite\ApplicationSuite.VAR Model\AxTable\Delta\VendTable.xml which suggests to me that the code upgrade has created "sub models" within the standard Application Suite or Application Foundation models. Should I be trying to merge these change 'down' to the standard models somehow? I'm pretty confident this isn't yet at the point of merging into the Main branch, though the instruction "If you are migrating from Dynamics AX 2012 R3 or earlier, you will be mapping to the metadata folder under the Main branch." within Configure VSO solution mapping section leaves an element of doubt.
