Hi,

I have got the following error when opening a project after an update was installed by LCS team.

Output window: ........ : error : Project node name 'AxLabelFile\TestLabel_en-US' is invalid.

Error list window: there are several errors but all of them mention 'namespace' and 'invalid child element' in common.

The element 'PropertyGroup' in namespace 'schemas.microsoft.com/.../2003' has invalid child element 'BuildTasksDirectory'/ in namespace 'schemas.microsoft.com/.../2003'. List of possible elements expected: ...

The element 'PropertyGroup' in namespace 'schemas.microsoft.com/.../2003' has invalid child element 'DBSyncInBuild' in namespace 'http://schemas.microsoft.com/developer/msbuild/2003' List of possible elements expected: ...

The element 'Content' in namespace 'schemas.microsoft.com/.../2003' has invalid child element 'Name' in namespace 'schemas.microsoft.com/.../2003'. List of possible elements expected: ...

Could you guide me to solve this issue?

Hi ShawnDEV,

It seems that that the fields 'BuildTasksDirectory','DBSyncInBuild' are required fields.

Please make sure you specify all required values.

And please do a full build.

Any progress Please let us know.

Hi ShawnDEV,

If you press right-click on the solution and click "Open folder in File explorer". Do you see the folder for project and inside that folder project file?

Hi ShawnDev,

If you open FleetManagementClassProject folder (inside FleetManagementClassProject), do you see *rnrproj file?

If yes, try to remove it from solution and add project again to the solution - right click on Solution -> Add - Existing project -> rnrproj file.

Hi,

Do you see label file TestLabel in ApplicationExpoler if you search by name? Do you know anything about this label file? If it's supposed to be a new model you should take from source control have you taken the latest version and refreshed models (Dynamics 365 -> Model management -> Refresh models)?

That TestLabel was created by me just for practice.

and Yesterday there was an upgrade on my demo environment by LCS team.

I cannot find this label in the explorer anymore also other elements like class, action menu item.

Then when I try to open the project, this issue occured.

Do you want me to refresh the model 'Flee Managment' ?

Hi ShawnDEV,

Have you added objects to "Fleet management" model directly? If yes, it was wiped by the update as it's MS model. For education purposes, you need to create a new model. I'm not sure if there is a point to try to open the old project as it only stores references to objects, but do not store objects itself.

Hi Sergei,

Okay. But even if I had a my own model, the changes like form changes, menu item changes are not displayed in the interface after an upgrade. I heard that in order to display those changes in the interface again, dll objects for the extensions should be created. Do you have any doc which I can learn from?

Hi ShawnDEV,

If you made own model and changes added to this model, the changes do not disappear after an update.

Check this one how to create own model and project for new model dynamicsinsights.com/.../
