Do you mean you need the source code? It is on [GitHub](https://github.com/MapWindow/MapWinGIS)

Hi Pmeems,

Thanks for the response. I got the code downloaded tried to compile it on VS 2015, but keep on getting the error on BindingListView and MW5.shared. I think the two Metadata file could not be found errors are caused by the two invalid option ‘7.1’ for /langversion. But for VS 2015, the language versions can only go to 6.0. Do you have any ideas?

The `/langversion` option is in the csproj-files I think. You can have a look at change it or have a look at the properties of the projects.

Another solution could be to install VS2017 Community and use it to compile MW5.

And if you want to reuse parts of MW5 I recommend creating a plug-in for MW5 instead.
