To help debugging I decided to download and compile the sources. I downloaded v18.104.22.168 and attempted to build the solution in Visual Studio 2008. After getting IlMerge and Windows Mobile 6 Snandard, I still had two minor errors I had to fix myself.
I only mention then so you can save others the grief:
1) In "Win Forms Zip Example.csproj", there is a reference to:
which I had to reduce to:
2) In "Zip CF Full DLL.csproj", there is a post-build event:
<PostBuildEvent>"\Program Files\Microsoft\ILMerge\ILMerge.exe" /targetplatform:v2,"C:\Program Files\Microsoft.NET\SDK\CompactFramework\v2.0 Debugger\BCL" /t:library /xmldocs /out:Ionic.Zip.CF.dll
I reserve my C: drive for the system and have everything else on D:, so the $SolutionDir is on D: The above command was looking for D:\Program Files\... I fixed it by putting in C: explicitly, but you should probably use something like %ProgramFiles%.
Hope this is helpful.
