File Not Found Exception in UWP projects

[Nicolaasjvv]

When porting a Windows 8.1 Universal app to Windows 10 UWP, we suddenly started getting File not found exceptions for classes using the priority queue. I tested it in isolation, creating a new project, referencing the latest PriorityQueue library (4.0.0) obtained through NuGet, and we still get the same.

Here are some details:

When does this happen
During run time, whenever a priority queue object is instanciated. Otherwize, the project builds just fine.

What happens

A file not found exception is thrown, here is the complete message:

An exception of type 'System.IO.FileNotFoundException' occurred in TestApp.exe but was not handled in user code

Additional information: Could not load file or assembly 'Priority Queue UWP, Version=3.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

How is the code used.

Just a simple initializer will do, see this sample:
TestPage.txt

Additional info
For Windows 10 UWP, the following target platforms and minimum versions were specified during project creation.

I cannot think of a reason for this to happen, all the files are safely where they should be, although with windows 10 projects, all NuGet packages are stored on disk under C:/{UserName}/.nuget/packages. All files are present.

I'm experiencing the same issue with the exact same configuration.

Looks like a versioning issue? You say you're using the latest version (4.0.0) but that error says it's looking for version 3.0.0. Try searching for Priority Queue UWP, Version=3.0.0.0 in your project/solution files and see what turns up.

I've added support for both .Net Standard 1.0 and PCL net40+sl5+win8+wpa81+wp8 in version 4.0.2. If this was caused by the library not supporting the correct framework version, it should be fixed now.

Please reopen if you encounter this issue again.
