WPF应用程序在Windows Server 2008上崩溃

Question

I received an error report regarding a WPF app that wouldn't start up in a Windows Server 2008 Service pack 2 server (the application is an administration tool we're distributing to our customers). Since this application has a lot of external references, I tried to simplify the problem by creating a simple WPF application using Visual Studio 2013: a plain white window with "hello world" showing and nothing more. I tried to make it run in the production server, with no luck: it always crashes immediately.

Here's what I have:

• the application was created with the standard VS 2013 template for WPF, so it had 3.5 as the target framework; i changed it to 4.6
• the server has the 3.5 SP1 and 4.6 versions of the .net framework installed
• the app.config is well-formed, with the configSections section on top, no additional references besides log4net, supportedRuntime tag set according to the target framework version
• I already checked that there are no project references from version 3.5 left in the project
• I already tried logging in the DispatcherUnhandledException and in the AppDomain.UnhandledException handlers
• the application runs in my development environment
• the application runs in production environment only if I change the target framework to 3.5. In this case, the WPF windows shows up and the log file is correctly produced
• I already tried producing a dump and trying to debug it in Visual Studio: I just get a "Source not available" message and a stack trace ending with ntdll.dll!NtWaitForSingleObject()

Answer 1

Just in case someone else stumbles on the same problem, looks like the KB4457921 update from Microsoft somehow solves the issue. If an update is not possible, consider porting the code back to .net framework v. 3.5.
