Could not load file or assembly 'Windows, Version=255.255.255.25

[CrunchingKoalas]

Hey guys,

I’m getting a weird exception when launching a Windows 8.1 application:

First-chance exception at 0x76CB1D4D in Template.exe: Microsoft C++ exception: Platform::COMException ^ at memory location 0x07A2E9D4. HRESULT:0x80131534 The text associated with this error code could not be found.

WinRT information: System.TypeInitializationException: The type initializer for ‘WinRTBridge.WinRTBridge’ threw an exception. —> System.TypeInitializationException: The type initializer for ‘WinRTBridge.TypeInformation’ threw an exception. —> System.IO.FileNotFoundException: Could not load file or assembly ‘Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null’ or one of its dependencies. The system cannot find the file specified.

at UnityEngineInternal.BootstrapHelpers.FillTypeMaps(Dictionary`2& type

Stack trace:
[External Code]

If there is a handler for this exception, the program may be safely continued.

I don’t have any errors when building the Visual Studio solution from Unity and I have the Compilation Override set to “Use Net Core”. I’m not using any Hashtables, ArrayLists, Queues or anything from the missing .NET classes.

An empty project compiles and works fine, but when we build our game it builds succesfully and then crashes at start.

I think I tried everything - please help, I’m getting desperate.

Cheers,
Tom

Are you able to create Windows Store Apps (Windows 8.1) application from Visual Studio, the error indicates that you may be missing Window SDK.

Also try building to empty folder.

This was the fix for the problem I just encountered. Wanted to put it out there for anyone else having this error. I added DOTween to my HoloLens project and couldn’t get the type to be recognized in my build. Only when I built the generated project to a new folder did the resulting build recognize the new plugin DLL files.

Thanks!
