I'm not sure which version you're referring to for RC1, did you mean SP1? The specific version is 2018.1.221 (aka "2018 R1 Service Pack 1")
The version number works like this;
- The 1st number is the year (2018)
- The 2nd number is the Release (1)
- The 3rd number is the date it was released (221 means Feb 21st)
Improvements since R2 2017
Now to your question, it appears you were using a pretty old version as you still have the renderers and Init() calls. Please read this article we have about the important changes that we made in R2 2017
Along with no longer needing to manually call TelerikForms.Init, you no longer need to define the renderers. I recommend going through each target platform and removing and renderer attributes that code as well as any other TelerikForms.Init() instances.
Additionally, we made finding the correct assemblies much easier, all of the required assemblies for each platform are in a single folder:
Since you're coming from a version that's more than a year old, I recommend just removing all of your current references and just re-adding them from the correct folders, or just use the NuGet package instead.
As to why you're not seeing the NuGet packages, this may be a credentials issue or you don't have Telerik Package Source selected. Here's a screenshot of what I'm seeing right now:
Lastly, make sure you've also updated the SkiaSharp dependencies. If you're using the Telerik NuGet package, this will happen for you. Otherwise, update all 3 SkiaSharp packages to 1.59.1 or later.
