I'm trying to use SharpZipLib under Windows Mobile 5.0 which has the Compact Framework v2.0 on it.

First off I couldn't just reference the SharpZipLib in my project because on deploy it would try and deploy all of the full .NET framework DLLs over to the device. So I opened up the SharpZipLib source in SharpDeveloper and changed the Target Framework to Compact Framework 2.0.

After a successful recompile it now deploys properly to the device but whenever I try to use FastZip I get a Type Load Exception which from what I can gather means that its for the wrong framework. Yet I had recompiled it for the compact framework.

Opening up the DLL in ILDASM gives me the following from the head of the manifest:

.assembly extern mscorlib
{
  .publickeytoken = (B7 7A 5C 56 19 34 E0 89 )                         // .z\V.4..
  .ver 2:0:0:0
}
.assembly extern retargetable System
{
  .publickeytoken = (96 9D B8 05 3D 33 22 AC )                         // ....=3".
  .ver 2:0:0:0
}

So the first one, B7...., is incorrect for mobile devices, while the second one, 96...., is the correct PKT for mobile devices. 

What do I have to do to get SharpZipLib to work under the Compact Framework??

Thanks
 

This is a bug in SharpDevelop's compact framework support which will be fixed for the final SharpDevelop 2.1 release.

As a workaround, go to the projects compilation options and check "Do not reference mscorlib.dll"; then use Project > Add reference to manually add a reference to mscorlib. Then SharpDevelop will call the C# compiler so that it uses the correct mscorlib version. You will probably see a compilation error for the missing methods, but there should be #ifdef directives in the SharpZipLib source code around all calls to methods that are not supported on the compact framework, so just set the correct compilation symbols.
