I had my Project on the Unity Cloud made with Unity 2018 (I don't remember the exact version).
Today I downloaded the latest version of Unity (2019.3.2f1) and tried to open my project.
I'm receiving a lot of errors like these:
Also, if I open the project with visual studio it compiles with no error.
I am not able to fix them in order to compile the project in Unity.
It sounds like you have an old version of package manager. Try to "Reset packages to default".

What I have done
I looked up a few tutorials and did all their steps. MRTK is successfully installed. I created a simple world in Unity 3D (latest version), with 2 moveable (using the hand interface) objects. In game mode, everything works fine.
Now I wanted to deploy it to my Hololens 2.
So I build the project with the following settings:
After that I connected my Hololense to the PC and want to deploy it via Visual Studio 2022.
It is set to "Release" "ARM 64" "Device".
After pressing on "start without debugging" i will get the following error Codes (as an image because it is better structured):
I already tried installing different SDK packages and creating 5 new Unity projects but it doesnt work. Hope you can help me!
Greetings!
Apart from the suggestions from derHugo, you may also check the following configurations of your project.
Make sure Unity is 2020.3 LTS, and you have used Mixed Reality Feature tools to import/update to the latest package.
Select a specific “Target SDK Version” and “Visual Studio Version” instead of “Latest installed”
In visual studio, make sure the Platform Toolset consists with Unity selection (v143 for vs 2022)
Reinstall “Universal Windows Platform development” component in VS installer and ensure any related to v143 ARM64 build tools are installed (because you are using vs 2022)
LNK1136 error is caused by corrupt or invalid files. Because to deploy a unity project to HoloLens, you need to build a Unity project first. If cleaning VS build then rebuilding is not working, try to remove Unity build then rebuild.

I'm building a new Xamarin Forms 5 app using VS 2022 17.1.1. Everything in the project appears to be up-to-date.
I've been working on this project for a while and never had this issue. All of a sudden it just appeared today. The last action I took was to install the Plugin.InAppBilling package, thought the package in question is not used by the Plugin.InAppBilling package.
The error is as follows:
All I can see is that the shared project is using System.Numerics.Vectors version 4.5.0 and it seems to be dependency of Xamarin.Essentials which is version 1.7.1 in my project.
However, the version number of System.Numerics.Vectors seems to be 2.0.5.0 in the Android and iOS projects.
I found the GitHub issue here but I'm not seeing any clear resolution to this issue. Even though it appears to be a warning, in my case, I can no longer run the app because I keep getting deployment error to the Android Emulator or actual device. It simply refuses to deploy my app to the device/emulator. So, it's really NOT a warning in my case. It's a show-stopper. I'm a bit surprised about how lightly the Xamarin Essentials folks seem to have taken this issue on GitHub.
Has anyone actually resolved this issue? If so, what's the solution?
BTW, in my case both the Android and the iOS projects are throwing this error/warning and both use System.Numberics.Vectors version 2.0.5.0 even though the shared project has version 4.5.0 installed as a dependency undre Xamarin Esssentials.
I'd appreciate some pointers on how to make this issue disappear. Thanks.
At first, you can try to update the Xamarin.Essentials package in the Android and IOS project with the nuget package manager to the version 1.7.1.
And then, if the error is still here, you can right click the reference and remove the reference of the System.Numberics.Vectors 2.0.5.0 both in your Android and IOS project. Then download the System.Numberics.Vectors 4.5.0 in the nuget package manager both too.
I receive this warning when ever I try to deploy my Xamarin.Froms app to any device or emulator. Also the deploy fails without any errors. I cannot run my app. Can Any one please help me?
The $(TargetFrameworkVersion) for Xamarin.Forms.Platform.dll (vv8.0)
is greater than the $(TargetFrameworkVersion) for your project (v7.1).
You need to increase the $(TargetFrameworkVersion) for your
project. App2.Android C:\Users\subas\source\repos\App2\App2\App2.Android\App2.Android.csproj
EDIT/UPDATE
Right now JDK9 and the Android SDK tools are not compatible with each other - thus Xamarin.Android does not work with JDK9.
Run the following to see the version of java you have installed:
java -version
If it reports something along the lines of java version "9.0.4" you have JDK9.
Specifically there's an issue with the apksigner. It's not using the -classpath switch that the JDK expects.
Easiest way to fix is to install the JDK8 and make sure your PATH is pointed at it.
This documentation gives a solid overview.

Sounds like the target Android framework in the project needs to be updated to point to the latest version of Android.
First - make sure you have the latest Android SDKs installed. Here's some documentation on that.
Once you have the latest - here is how to make sure you're targeting the latest - depending on the IDE you're using:
Visual Studio Mac
In the solution explorer, right click the Android project and select options.
Under the Build -> General node - select "Use latest installed platform" from the Target Framework dropdown.
Save everything, close the solution, restart VS-Mac
Visual Studio
Right click the Android project in the solution explorer and select properties
Under the Application node, select Use Latest Platform from the Compile Using Android Version dropdown.
Save everything, close the solution, restart Visual Studio
When I build my project in debug mode it builds forever. However there is no problem building in release mode.
This problem first occurred when I updated visual studio for mac to the newest version:
Preview 6 (7.0 build 2740).
This is what my debug settings look like:
Any ideas are much appreciated.
Check for xamarin.forms updates in both in the ios and xamarin project. It could be that theese are not updated even though the solution is updated.
Xamarin.forms package under the iOS project might have an older version
I cannot really help you because I don't know what type of project you tried to run or which OS X you are working with.
If such an Error occurs, always check your code or try restarting your mac.
Tip: "Visual Studio for Mac Preview" is still in its Alpha. Use the Stable Update channel to avoid errors like this.
I am developing a Xamarin Forms (PCL) application for IOS and Android Platform.
My Xamarin Studio version is 5.5.4 (Build 15). I am on stable channel.
My Xamarin Forms dll version is 1.3.0.6292.
I have also added a Xamarin Forms Labs reference from NuGet, v1.2.0.
Since yesterday, whenever i am building the solution, i get following error:
error : Error initializing task XamlG: Not registered task XamlG.
Any possible resolution for this error? I have tried clean and build multiple time. Even deleted the entire source code and redownloaded everything from source control but same error.
This error can occur if you have upgraded from an older version of Xamarin.Forms to a newer version. The underlying problem is that the wrong Xamarin.Forms.Build.Tasks.dll is being loaded compared with the one that the custo MSBuild Xamarin.Forms.targets file is expecting.
There is a bug in Xamarin Studio where the old build Xamarin.Forms build tasks are still used after the NuGet package has been upgraded. You can workaround this by closing and re-opening the solution.
However you say you have deleted the source code and downloaded everything again so it sounds like you have a different problem. It may be that your project is trying to use two different versions of Xamarin.Forms at the same time. I would look at your project files (.csproj) in a text editor and make sure they are all using one version of Xamarin.Forms. Check that they are all referencing a single version of Xamarin.Forms.targets and it is the same version.
This is silly.
I just recloned the project in a new fresh folder and build it from scratch and it worked. The more i am using Xamarin Forms, the more buggy and unbaked it seems. There are random issues which get fixed just by rebuilding the project. Or like Matt pointed in his answer below, by just restarting the studio. In my programming experience with different IDEs and platforms, only Xamarin seems to have these problems regularly.
