Easily Clean Bin/Obj Folders

In an earlier blog post I talked about how to clean up space on your Xamarin Developer machine by deleting old installations, NuGet cache, and Android junk sitting around. We can take it one step further and delete all of that clutter that is built up in the bin/obj folders! This can be gigs of data. Here is my GitHub folder: Inside of each of my repo folders sits code and the bin/obj folders from each build, which can be very large as it contains the full excecutable. What we can do is write a…

Dynamically Changing Xamarin.Forms Tab Icons When Selected

Spicing up your Xamarin.Forms tab can easily be done in a few ways.

Well Google Admob doesn’t exist on UWP, but Microsoft has their own advertising SDK that you can integrate and it of course works with Xamarin.Forms! Here is what you need to know to get started. Install the SDK or NuGetBefore we get started, we need to install the official SDK for Microsoft Advertising, which is us…

Moving Plugins for Xamarin to .NET Standard

I could never imagine the amazing response to Plugins for Xamarin, those amazing little libraries that abstract away all that platform specific code into a lovely cross-platform API for iOS, Android, and Windows. They sure have grown, with hundreds of plugins be generated by the community and with tons of installs. My plugins alone have now hit 3 Million installations! With all this momentum it is a great time to look to the future, simplify plugins, and take the leap to .NET Standard. What is .…
