Xamarin: Unable to add HotTuna.StarterPack - xamarin

I am trying to install the MVVMCross.HotTuna.StarterPack on my Xamarin (Mac) Solution using the NuGet, but i ain't successful. The package was installed in the Xamarin.Android project successfully but while i try the same to do with the iOS and PCL project, it doesn't add. Any Idea on whats going wrong? Thanks!

That nuget package requires nuget 2.5 which isn't yet finished/released for Xamarin Studio - track https://github.com/mrward/monodevelop-nuget-addin/issues/13 for updates
It will also probably require fixes from Xamarin - they've not yet released PCL support, but it is in development. You can ask their forum and/or support for updates on this.
In the meantime:
you can develop for MvvmCross using VS on the PC - see http://mvvmcross.wordpress.com/
you can develop using binaries (not nuget) on the Mac - see http://slodge.blogspot.com/2013/05/xamarin-studio-quick-run-through-for.html
For Xamarin.Mac/MonoMac support, there's no PCL support currently available - so the only way to get this working currently is to fork the MvvmCross solution and to compile the PCL libraries for the appropriate Mac project.

Xamarin SDK was not found for JetBrains Rider

I am hoping to work with Xamarin for a project, primarily to learn a little about cross-platform app development, and would prefer to stick to developing on Linux. This led me to attempt to work with the JetBrains Rider IDE, something that I believed to be fairly well documented, as per these resources:
Xamarin.Android on Linux (in coordination with its Ubuntu 19.04 update post)
Failed to load Xamarin Forms project with .NET Standard 2.0 Lib in Rider
0xFireball's Xamarin.Android on Linux guide with associated Rider/IDE setup
I've been able to install everything just fine, Android Studio and Rider were installed via JetBrains Toolbox (I also tried installing Rider manually, but it made no change), and I am able to create the project and configure the Android settings for the Xamarin project.
This is where my luck ends, since despite trying the various resources I've linked above, including reinstalling mono and dotnet-sdk multiple times, I get this error no matter what I try:
Xamarin SDK was not found: Rider was unable to find Xamarin SDK on
this machine. Xamarin-based projects will not be loaded. Please
install Xamarin SDK or change toolset.
I've tried following the instructions both on a manually installed Rider 2019.1.3 (Build #RD-191.7141.460) and Rider 2019.2 EAP (Build #RD-192.5895.291).
I'm fairly new to the world of Xamarin, so I'm not sure where to begin looking. What exactly is the Xamarin SDK (is it just Xamarin.Android?), and what should I be checking my setup for in order for Rider to detect the Xamarin SDK?
It appears that what Rider installs via its Environment page, is only the Xamarin Android package. Not the actually Android Studio SDK, which is needed to develop any android apps. You have to download that separately.

Multiple errors after updating Xamarin Forms

I'm using Visual Studio 2017, and I stared a new Xamarin Forms app:
Create New project - Cross Platform App (Xamarin)
Blank App, and I chose Portable Class Library (PCL)
The app compiles and runs.
Now I right click the solution and choose Manage Nuget packages for solution, and it tells me I'm running version 23.3.0 and I should update to 25.4.0.1
After the update and 3 VS reboots, it gives me a host of errors I have been trying to solve for an hour including googling.
All theme related.
I tried removing the styles.xml file all together. I removed the theme from the reference to the theme from the manafest and it keeps putting it back.
I can't figure out what I'm doing wrong. I have not written any code.
Xamarin Forms requires a specific version of the Android Support libraries. Do not update them.
Delete your project and create a new one.
It is possible to get round this limitation by ensuring you are using a specific version of Android and by updating all Android SDK's, but for a beginner I would recommend just using the support libraries that are installed alongside Xamarin Forms.

Can not compile after migrating unified api in xamarin forms

We have migrated the xamarin forms project to unified api.
But we have the strange compile error like this:
Could not AOT the assembly '.../iOS/obj/iPhone/Debug/mtouch-cache/Build/Xamarin.Forms.Labs.dll
So I changed the settings in iOS project's options.
In ios Build Tab of Project options(iOS) I changed the "don't link" to "Link all assemblies".
But the app is crashed when it is started.
xamarin version is 5.7.1(build 17).
xamarin forms's version is 1.3.5.6337.
xamarin forms labs's version is 1.0.1.5.
Please help me if you have the experience with this error.
Replace Xamarin.Forms.Labs with XLabs.Forms.
There has been a major refactoring on how the XLabs project is structured so your existing project based on the 1.x.x will break. The reason for the refactoring was simple; separate functionality that does not depend on Xamarin.Forms into different assemblies. This allows the use of functionality like IoC, Serialization and even platform specific services without referencing XF.
To upgrade:
Uninstall any existing Xamarin.Forms.Labs packages from your
project.
Install XLabs.Forms package to your projects (PCL, iOS, Droid & WP). This will update Xamarin.Forms to the latest stable release (1.4.x)
Refactor code to reference the correct namespaces.

MvvmCross as "Native" Libraries

I have a project which greatly depends on ServiceStack, unfortunately the V4 releases, which includes PCL release for most platforms(especially after forking out for a Xamarin Licence), is just way out of my price range as an ISV. I have cloned the MvvmCross code but before I start messing around I would like to know what pitfalls I could run into when attempting to create a Non PCL based version compatible with the platforms I target (Currently Xamarin.Android, WPF and WinRT). The idea would be to able to reuse the code for the WPF project to build Android and WinRT clients.
Does anyone have any pointers?
I don't think there is any problem or pitfall with what you are describing - and I don't think you'll need to fork the MvvmCross source.
You should be able to build your apps as native code, and should then be able to reference the MvvmCross PCL libraries directly from the native libraries you are building - you don't need to rebuild MvvmCross to do this. Plenty of people already use MvvmCross using "file linking" rather than PCLs - it's not the default setup encouraged by the Nuget packages, but it still works fine.

Monogame and MonoDevelop missing IDE MacOSX

I tried installing monogame and monodevelop but after downloading and installing the required applications there is no Monogame IDE in my application folder.
What i did was the following:
Started on the monogame download page (http://www.monogame.net/downloads) and followed the corresponding links to download these files for OSX:
Xamarin Studio 4.0.12 installer
Mono + GTK# to which it linked me to the mono download page to which i download
The Runtime and SDK files for OSX Version 2.10.x
I installed each program in the corresponding order and continues the installation process by downloading the MonoGame installation V3.0.1 for Xamarin and MonoDevelop because i wasnt sure which one to get. But when I couldn't simply drag or click to install I looked in my application folder there was no Monogame IDE only the Xamarin Studio IDE which I presume is the correct process. But When I opened the Xamarin IDE it says that I've download the starter version and I cannot use Monogame.
Aside from the monogame website and various googling instructions, I've tried following these very clear instruction from this blog (http://mastrgamr.net/xna/programming-xna-on-mac/) but got stuck when I could find nor open my MonoGame and the Xamarian IDE displaying the correct screen.
I do not understand what I am doing wrong as the installation instructions seem very clear.
EDIT:
So i found out that Xamarian IDE replaced the MonoDeveloper IDE though the instructions I've found are using MonoDeveloper IDE as the example. I'm not sure if theres a significant difference but I presume there is a difference as I still can't seem to run monoGame and the outdated instructions aren't syncretic with my actions. Can anyone provide me with updated Xamarian instructions?
A little while ago Xamarin replaced MonoDevelop with Xamarin Studio. So MonoDevelop is now called Xamarin Studio and it looks and behaves a little different. That's why any tutorials talking about MonoDevelop are going to be a little confusing.
I've never tried to install Xamarin Studio on a Mac so I'm not sure what the error is about the starter version. However, I suspect it might be talking about the Xamarin licensing.
What I can tell you is, you won't be able to develop games with MonoGame on the starter edition if you are targeting platforms other than Windows (this includes Android, iOS and I presume Mac) due to the limited app size. You should consider buying a license from Xamarin if this is indeed your issue.
