Cannot load shared 'project' in Windows Un

问题:

I've just installed the April 2015 release of the Azure SDK. It is version 2.6 and previously I was on 2.5. Now one of my projects will not load. It is the shared project in a Windows Universal application.

When I right-click the project and choose 'reload' I get the pop-up error

The method or operation is not implemented

The output window gives more detail:

Things.Shared.shproj : error : The composition produced a single composition error. The root cause is provided below. Review the CompositionException.Errors property for more detailed information.

1) No exports were found that match the constraint: ContractName Microsoft.VisualStudio.ProjectSystem.References.IBuildDependencyProjectReferencesService RequiredTypeIdentity Microsoft.VisualStudio.ProjectSystem.References.IBuildDependencyProjectReferencesService

Resulting in: Cannot set import 'Microsoft.VisualStudio.Azure.Deployment.ProjectReferenceMaintenanceService.ProjectReferencesService (ContractName="Microsoft.VisualStudio.ProjectSystem.References.IBuildDependencyProjectReferencesService")' on part 'Microsoft.VisualStudio.Azure.Deployment.ProjectReferenceMaintenanceService'. Element: Microsoft.VisualStudio.Azure.Deployment.ProjectReferenceMaintenanceService.ProjectReferencesService (ContractName="Microsoft.VisualStudio.ProjectSystem.References.IBuildDependencyProjectReferencesService") --> Microsoft.VisualStudio.Azure.Deployment.ProjectReferenceMaintenanceService

Resulting in: Cannot get export 'Microsoft.VisualStudio.Azure.Deployment.ProjectReferenceMaintenanceService.WireUp (ContractName="Microsoft.VisualStudio.ProjectSystem.ConfiguredProject.AutoLoad")' from part 'Microsoft.VisualStudio.Azure.Deployment.ProjectReferenceMaintenanceService'. Element: Microsoft.VisualStudio.Azure.Deployment.ProjectReferenceMaintenanceService.WireUp (ContractName="Microsoft.VisualStudio.ProjectSystem.ConfiguredProject.AutoLoad") --> Microsoft.VisualStudio.Azure.Deployment.ProjectReferenceMaintenanceService

The other parts to the Windows Universal app (the Windows 8.1 project and the Windows Phone 8.1 project) have two Azure NuGet packages installed: Windows Azure Mobile Services 1.3.2 and Windows Azure Storage 4.3.0. (N.B. Those two projects load without issue.)

This is not a show stopper for me since uninstalling the Azure SDK 2.6 removes the load failure. To uninstall I go via the Control Panel to 'uninstall or change a program' and then uninstall Microsoft Azure Tools for Microsoft Visual Studio 2013 - v2.6

I would like to know how to fix this without uninstalling the Azure SDK 4.6.

回答1:

Over on the Azure Mobile Services forum Chuck Weininger has posted the following answer:

The [fixed] build of Azure SDK 2.6 is now available, but it may not have propagated to all download servers yet.

You can run the Web Platform Installer and if you don’t have the new build installed, it should allow you to install 2.6 again. But it might not if you are accessing a download server that doesn’t have the new bits yet. If WebPI doesn't allow you to install 2.6 again, then wait a few hours and try again.

The build number for the version with the fixes is build 2.6.30508.1601. You can identify the build of the SDK from Control Panel -> Programs and Features -> Microsoft Azure Tools for Microsoft Visual Studio 2013 – v 2.6. The Version column will display the build number

I have followed Chuck's instructions and have the new build and the shared project now loads without issue.

We have been able to reproduce the issue, but don't have a workaround at this time. If you want to use the Universal App projects with VS 2013, you will have to uninstall Azure SDK for VS 2.6. The issue does not happen on VS 2015 RC if you would like to give that a try. We hope to have news soon about how we can get a fix for this issue on VS 2013.
