Steps to Reproduce

1. When I introduced this SpreadsheetGear library in nuget and called the relevant methods of the SpreadsheetGear library in my MyView.
2. objcgen /Users/wushenglei/Projects/hello-from-csharp/hello-from-csharp/bin/Debug/hello_from_csharp.dll --target=framework --platform=iOS --outdir=output -c --debug

Expected Behavior

Generate the corresponding .framework file

Actual Behavior

Error log

Environment

OSX 10.14.6 embeddinator-4000 0.40 Visual Studio for Mac 8.4 build 2653 SpreadsheetGear 8.3.25.102

Build Logs

Example Project (If Possible)

hello-from-csharp.zip

Switch to the "Preview" tab to ensure your issue renders correctly. -->

So the problem is that in the bin folder:

ls  /Users/donblas/Downloads/hello-from-csharp/hello-from-csharp/bin/Debug/
hello_from_csharp.dll hello_from_csharp.pdb

we don't see that DLL, so it can't be processed.

In c# library projects don't copy their dependencies next to the output.

If I manually copy the dependency next to it:

 $ cp ~/.nuget/packages/spreadsheetgear/8.3.25/lib/netstandard1.3/SpreadsheetGear.dll /Users/donblas/Downloads/hello-from-csharp/hello-from-csharp/bin/Debug/

Then the build completes for me.
