Windows Phone 8 app does not contain a definition for InitializeComponent
c#, visual-studio-2015, windows-phone-8, xaml
Solution
the same started to happen to me today; to reproduce the issue, I just open Visual Studio 2013 Update 4, create a blank Windows Phone 8.1 and double click on MainPage.xaml.
I solved by performing the following (a mix of what I've read around the web):
- exit all Visual Studio instances
- delete everything on %localappdata%\Microsoft\VisualStudio\12.0\Designer\ShadowCache
open a command prompt with admin rights and execute the following commands:
pushd %VS110COMNTOOLS%
icacls ..\IDE /grant *S-1-15-2-1:(OI)(F)
icacls ..\IDE /grant *S-1-15-2-1:(CI)(F)
icacls ..\IDE\PrivateAssemblies /grant *S-1-15-2-1:(OI)(F)
icacls ..\IDE\PrivateAssemblies /grant *S-1-15-2-1:(CI)(F)
icacls ..\IDE\PublicAssemblies /grant *S-1-15-2-1:(OI)(F)
icacls ..\IDE\PublicAssemblies /grant *S-1-15-2-1:(CI)(F)
finally, reboot. worked on Windows 8.1 64-bit.
Problem
I have just downloaded the 14 CTP version of Visual Studio and created a blank app for Windows Phone. I tried to open the `MainPage.xaml` and the designer shows up the following errors: and for those who can't see the image: ``` System.Exception Package failed updates, dependency or conflict validation. Windows cannot install package App.a5cd6ef3c.a895b.a4508.a96fd.af1634c30bb13 because this package depends on another package that could not be found. This package requires minimum version 0.0.0.0 of framework Microsoft.VCLibs.140.00.Debug published by any publisher to install. Provide the framework along with this package. at Microsoft.Expression.HostUtility.Platform.AppContainerProcessDomainFactory.CreateDesignerProcess(String applicationPath, String clientPort, Uri hostUri, IDictionary environmentVariables, Int32& processId, Object& processData) at Microsoft.Expression.DesignHost.Isolation.Primitives.ProcessDomainFactory.ProcessIsolationDomain..ctor(ProcessDomainFactory factory, IIsolationBoundary boundary, AppDomainSetup appDomainInfo, FrameworkName targetFramework, String identifier, String baseDirectory) at Microsoft.Expression.DesignHost.Isolation.Primitives.ProcessDomainFactory.CreateIsolationDomain(IIsolationBoundary boundary) at Microsoft.Expression.HostUtility.Platform.AppContainerProcessDomainFactory.CreateIsolationDomain(IIsolationBoundary boundary) at Microsoft.Expression.DesignHost.Isolation.Primitives.IsolationBoundary.Initialize() at Microsoft.Expression.DesignHost.Isolation.Primitives.IsolationBoundary.CreateInstance[T](Type type) at Microsoft.Expression.DesignHost.Isolation.IsolatedObjectFactory.Initialize() at Microsoft.VisualStudio.ExpressionHost.Services.VSIsolationService.CreateObjectFactory(IIsolationTarget isolationTarget, IObjectCatalog catalog) at Microsoft.Expression.DesignHost.Isolation.IsolationService.CreateLease(IIsolationTarget isolationTarget) at Microsoft.Expression.DesignHost.Isolation.IsolationService.CreateLease(IIsolationTarget isolationTarget) at Microsoft.Expression.DesignHost.Isolation.IsolationService.CreateLease(IIsolationTarget isolationTarget) at Microsoft.Expression.DesignHost.IsolatedDesignerService.CreateLease(IIsolationTarget isolationTarget, CancellationToken cancelToken, DesignerServiceEntry& entry) at Microsoft.Expression.DesignHost.IsolatedDesignerService.IsolatedDesignerView.CreateDesignerViewInfo(CancellationToken cancelToken) at Microsoft.Expression.DesignHost.Isolation.IsolatedTaskScheduler.InvokeWithCulture[T](CultureInfo culture, Func`2 func, CancellationToken cancelToken) at Microsoft.Expression.DesignHost.Isolation.IsolatedTaskScheduler.<>c__DisplayClass5`1.<StartTask>b__7() at System.Threading.Tasks.Task`1.InnerInvoke() at System.Threading.Tasks.Task.Execute() ``` I entered `App1.xaml.cs` and `MainPage.xaml.cs` and I've seen that App and MainPage, respectively, don't have a definition for `InitializeComponent()`. The project is in the state it was created by Visual Studio, I haven't changed anything! Why is this happening and how can I solve it?
