New Post: Windows Phone 7.8: MissingMethodException when calling MoveToNextEntry()

I'm trying to use SharpCompress in Visual Studio 2010 Express for Windows Phone 7. Here's my simple code:

IsolatedStorageFileStream inputFile;
RarReader reader;

inputFile = IsolatedStorageFile.GetUserStoreForApplication().OpenFile("myfile.rar", FileMode.Open);



reader = RarReader.Open(inputFile);
reader.MoveToNextEntry();  // This raises an exception

inputFile.Close();

But when running this code I'm getting:

Method not found: lag rlib, Version=3.7.0.0, Culture=neutral, PublicKeyToken=969DB8053D3322AC.System.Enum.

at

reader.MoveToNextEntry();

Using this code:

IReader reader;
reader = ReaderFactory.Open(inputFile);

I'm also getting:

Could not load type 'System.Func`2' from assembly 'mscorlib, Version=3.7.0.0, Culture=neutral, PublicKeyToken=969DB8053D3322AC'.

Any ideas?

Thanks in advance.
