com.android.tools.r8.CompilationFailedException

When trying to build my Xamarin project in Visual Studio 2022 I am receiving this error:
java.lang.RuntimeException: com.android.tools.r8.CompilationFailedException: Compilation failed to complete, origin: obj\Debug\120\lp\100\jl\bin\classes.jar : com/google/android/gms/measurement/internal/zzai.class
My build log shows this:
Error in obj\Debug\120\lp\100\jl\bin\classes.jar:com/google/android/gms/measurement/internal/zzai.class:
Type com.google.android.gms.measurement.internal.zzai is defined multiple times: obj\Debug\120\lp\100\jl\bin\classes.jar:com/google/android/gms/measurement/internal/zzai.class, obj\Debug\120\lp\101\jl\bin\classes.jar:com/google/android/gms/measurement/internal/zzai.class
I have used 7zip to extract the specified zzai.class file however I don't know what to do from here. Trying to edit the file in notepad++ just shows noninterpretable code.
I fixed the issue by uninstalling unnecessary NuGet packages for Xamarin.GooglePlayServices.Measurement, only keeping the dependent packages required for Xamarin.Firebase.Analytics:
Xamarin.GooglePlayServices.Measurement
Xamarin.GooglePlayServices.Measurement.Api
Xamarin.GooglePlayServices.Measurement.Sdk

asp.net core 2.0 app publishing taking over 20 mins -- then won't load

I have an application with about 6 Nuget packages and 3-4 local project references. The local build is fast and runs as expected. When I set up a profile to publish in release mode to local folder for file deployment, it will list out thousands of lines in build output resolving tons of packages for easily 20-25 mins.
Once this process completes, the site errors out in a 500 complaining about missing:
An unhandled exception has occurred: No service for type 'Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration' has been registered.
I have tried to disable AI on entire application. removed all references and even disabled via the JSON config using:
ASPNETCORE_preventHostingStartup": "True"
waiting 20-25 for each publish process to complete is painful. but to then have it fail because of this error repeatedly is driving me mad.
What am I missing?

How do I run Lightswitch projects in Visual Studio 2015 without any errors?

I have created a simple Lightswitch desktop application in Visual Studio, added one table, and one search screen. When I ran it for the first time, it has shown a window with search screen with a red X mark. Hover over, it displays "Unable to load data. Please check your network connection and try loading again."
I've tried searching for lengthy hours with no luck. I've also tried the answers in this page without any luck. I have also tried granting permissions of all levels on the working directory of the project. Please help, this is very frustrating as I've expected so much from Microsoft but they failed to troubleshoot their faulty product.
Additional Information:
I am using Windows 10 Home, i7, 16 GB RAM, Visual Studio 2015 Ultimate with Update 3. I've tried to clean the entire solution and then debug. There is 1 error and 14 warning messages, here's the error:
<!--The Development Database is built in the same location - Bin\Data - for all configurations.-->

And here is one of the 14 errors:

Error deploying to AWS through visual studio

My co-worker is able to deploy our projects to AWS Elastic beanstalk fine. However I have issues on both my work machine and my home laptop. Both computers have the same error in AWS window pane.
I get a pop up as follows:
Deployment of the website failed due to errors during build of the deployment archive,
check visual studio output window 'Build' and/ or 'Amazon Web Service' panes for more details.
Then in the amazon window pane I get a different error everytime I try to run the deployment.
Example 1:
...package build 'CopyPipelineFiles': error in 'C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web\Microsoft.Web.Publishing.targets' at (1413,5): Copying file Web.config to obj\AmazonDev\TransformWebConfig\original\Web.config failed. Could not find file 'Web.config'.
Example 2:
...package build 'TransformXml': error in 'C:\Users\Andrew\colony\colony-website\Colony.Web\Colony.Web.csproj' at (840,5): Could not open Transform file: Could not find file 'C:\Users\Andrew\colony\colony-website\Colony.Model\Web.AmazonDev.config'.
Seems to be a different error each time -- I'm not sure how to even begin to look for any issues.
Jim Flangagan's comment is the answer: ReSharper 8.2 is causing this problem. To resolve either disable resharper ( Tools>Options>ReSharper>General>Suspend Now) or upgrade Resharper.

Windows 8 Blank App + DEP0700 error

I've found a few posts mentioning this error, but none that have helped. I created a new C# Windows Store project, and when I try to build and run it on the simulator, I get the following error in visual studio:

Any ideas? I've given full control to everyone on the project, have restarted multiple times, tried reinstalling visual studio, and am running Visual Studio as an administrator. Any help would be appreciated!
I got this to "work" by killing and restarting explorer.exe based on suggestions from a different google search I found. Doesn't really make sense to me, or seem to work reliably, but it does work sometimes at least... o.O
edit
A more permanent solution that worked was some combination of reinstalling Visual Studio 2012 and installing Visual Studio Update 1.
I was getting the same error and in my case neither cycling explorer.exe nor uninstalling/reinstalling Studio 2012 Ultimate with Update 3 worked.
What did work was starting up Visual Studio 2012 with "run as Administrator"
Seems, the issue has to do something to installing app both to local machine and to simulator
My case is i duplicate a WP 8.1 project and add merge some code to the duplicated project.
After i done the merge, I got "Package can't be registered" message when i deploy it to emulator.
But my original WP 8.1 project is successfully running on the emulator.
The root cause is i delete some app logo png image.
The VS2013 wont tell u that image is missing but display "Package can't be registered".
Hope this helps.
This happened to me after uninstalling a custom app that was installed using VS and trying to re-install a new version through either VS or directly using the Add-AppDevPackage.ps1 script
While it is not what you want to hear, a reboot fixed this for me. I tried killing the explorer process and restarting it as mentioned above, but this did not work for me.
