Getting error while adding some nuget packages to xamarin.android project.
Error-
Could not install package 'Xamarin.GooglePlayServices.Ads 42.1021.1'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v6.0', but the package does not contain any assembly references or content files that are compatible with that framework.
The latest GooglePlayServices packages need Android 7 and above. In order for you to use in Android 6, you will need to use older packages.
Or you can just update the target platform to v7 and above.

I get this error message in Visual Studio for Mac Community 8.10.21 (build 4) when I want to update my nuget packages in my Android project: Could not update packages.
Checking compatibility for Xamarin.AndroidX.Browser 1.4.0.1 with MonoAndroid,Version=v10.0.
Package Xamarin.AndroidX.Browser 1.4.0.1 is not compatible with monoandroid10.0 (MonoAndroid,Version=v10.0). Package Xamarin.AndroidX.Browser 1.4.0.1 supports:
monoandroid12.0 (MonoAndroid,Version=v12.0)
net6.0-android31.0 (.NETCoreApp,Version=v6.0)
Incompatible packages: 5
nuget packages image
How can I update the 5 nuget packages?
According to the error message, you need to update your monoandroid10.0 to monoandroid12.0.
So you can set the Target Framework in your project as android 12.0 and then try to update the nuget packages.

I'm getting this error when using maps in Android:
System.MissingMethodEsception: Method
'Xamarin.Forms.maps.Android.MapRenderer.OnCameraChange' not found.
And I've read that you can update the nugetpackage to fix the issue. However, I cannot install it due to this:
Could not install package 'TK.CustomMap 2.0.1'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.5,Profile=Profile78', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
The updates of packages installs just find in iOS and Android but not for PCL. I've tried to remove all the packages and then tried to add TK.Customs nuget package but this same issue.
Also tried to install it on a fresh project and that installed just fine. Just cant get it to install on my old project.
Here is the whole error message when trying to update package:

Could not install package 'TK.CustomMap 2.0.1'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.5,Profile=Profile78', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
The pre-release version (at least pre2) of TK.CustomMap supported all platforms (see here), anyway, as of pre3 (see here), obviously the support for all platforms was dropped in favor of .NET Standard (1.1 in this case).
The profile you are using in your PCL does not seem to be compatible with .NET Standard 1.1, hence NuGet fails to add the reference. You may try to switch to another profile (.NET 4.5.1 for example), but I don't know if that would help. Another option would be to migrate your projects to .NET Standard. It's kind of a stupid, repetetive task, but it's possible.
I Try to Install Microsoft.Identity.Client Nuget to my Xamarin.Forms Project. But every time i try to install the package I always get this error message:
Could Not install package ' Microsoft.Identity.Client 1.0341221-alpha'. You are trying to install this Package into a project
that targets '.NetPortable,Version=v4.5,Profile=Profile259, but the package does not contain any assembly references or content files that are compatible with that framework for more iformation, conct the package author
What should I do here, I have already tried all version of the package, and try to install the package from Package Manager Console
The error is very clear, the NuGet does not contain any target platforms that are supported in your PCL profile 259.
You should migrate your PCL to a .NET Standard library, at least version 1.1 to consume the NuGet package in your shared code. Alternatively, you could abstract it away with an Interface and Dependency Injection, which probably will be more time consuming.
I tried a lot, but I can't install Microsoft.ProjectOxford.Face NuGet into Xamarin Studio iOS project.
I got this error:
Could not install package 'Microsoft.ProjectOxford.Face 1.2.5.1'. You are trying to install this package into a project that targets 'Xamarin.iOS,Version=v1.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
I tried to update all packages, also Xamarin and still same problem. Only this package does not work - other like Newtonsoft.Json, Mircosoft.Net.HTTP and many other was installed correctly. I tried to install first Microsoft.BCL also Microsoft.BCL.Build and it also does not work.
Maybe you have any thoughts what can I do to make it work?
Unfortunately this is a problem with the Microsoft.ProjectOxford.Face 1.2.5.1 NuGet package itself. Whilst it has a portable class library (PCL) folder this does not map to a valid PCL profile:
portable-net45+wp80+win8+wpa81+aspnetcore50
If the aspnetcore50 part of that folder is removed then it would install into Xamarin.iOS. As it is, NuGet will not allow you to install it.
The only thing left you can do is unzip the NuGet package and try directly using the assembly. NuGet will not allow you to install it.
I believe there are plans to update the NuGet package to fix this, but that has not yet happened.
I am completely new to xamarin studio. I am trying to add a nuget package. using the add packages dialogue appears to be working however I get an error:

This is the github page for the package.

I tried to use different PCL profiles to no effect. I'm not sure how to determine which profile should be used.
The package targets only "Xamarin.iOS". You can't reference it in a PCL that targets more than that, since any other platform wouldn't be able to use it.
Either don't use a PCL, or restrict the PCL to "Xamarin.iOS".
Since this seems to be a UI component, you should reference it from your main project instead, and maybe expose some functionality through services to the PCL, if needed.
