After recent Xamarin Studio (Mac OS) update I'm no longer able to build my PCL with OfType extension method usage. For some reason it starts to complain that method is not there:
Error CS1929: Type object[] does not contain a member OfType and
the best extension method overload
System.Linq.ParallelEnumerable.OfType<namespace.TetsClass>(this
System.Linq.ParallelQuery) requires an instance of type
System.Linq.ParallelQuery (CS1929)
If I create a new test project - it works fine with exactly the same code so the issue in my existing project and/or some referenced projects.

After upgrading Visual Studio to version 17.3.6 (build 20), the Xamarin.iOS project is failing to build with the following error:
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.Shared.targets(4,4): Error MSB4028: The "ParseBundlerArguments" task's outputs could not be retrieved from the "Aot" parameter. Parameter "includeEscaped" cannot have zero length. (MSB4028)
The problem lies in the project file itself:
<MtouchExtraArgs>-i18n=west -aot "nimt-trampolines=512" --registrar:static</MtouchExtraArgs>
It's complaning about -aot parameter and it's value. If I replace it with as following (space replaced with equal sign) then all is compiling fine:
<MtouchExtraArgs>-i18n=west -aot="nimt-trampolines=512" --registrar:static</MtouchExtraArgs>
Does anyone can help to confirm that this is a new correct way for specifying the -aot parameter?

You should specify the -aot parameter like below:
--aot=ARGUMENT
Add ARGUMENT as an argument to the static compiler.
I really hope someone here can help me out.
With a Xamarin.Forms application for one of our clients I currently have a major issue with the App freezing on iOS. This started as a random issue last year without a pattern behind it, different iOS models and different iOS versions were showing this issue.
The problem for me at the time was that no diagnostics event was triggered in Visual Studio App Center, so I did not have any error messages or crash logs in order to follow up on the issue. Now since upgrading to iOS 16 I have the problem on my phone as well now and strangely enough, we thought it would always trigger on Sundays, but this is not the case, it is random, and the only way to resolve the issue is to uninstall the app and then it will work for a while.
I basically ruled out all the probable causes from our application code, updated all the Nuget packages and even tried an older XCode version. Still, all of my attempts have gathered no results. From what I was able to glean while debugging, the App halts somewhere in Native Code where the Mono Debugger can not follow, so the iOS Device Log is my only hope to figure this out.
Current behaviour
App launches
All data is correctly pulled from Servers
Start page is properly updated
App remains unresponsive to touch inputs, no errors given

Below is a iPhone Console Log from the application starting, running and also crashing after tapping around on screen for a few seconds. All messages that are obvious to me I already checked via Google, but no real helpful information came out.
iOS Device Log
Due to the length, I published it as a Gist: iOS Device Log
I hope someone can point me in the right direction since we are approaching a major update for the App and we would like to ensure that the App works as intended.
Thank you very much in advance for all the support.
I'm new to Visual Studio, but not to programming. I tried to open a project which someone else sent me, and there are lots of errors (they are all the same). Please see the image below:
When I tried to check the runtimes installed, I see this:
I know that Newtonsoft.Json is installed, because I can see it in the packages folder.
So far I have looked at:
Getting "type or namespace name could not be found" but everything seems ok?
But I can't figure out how to fix the problem, as I'm using VS after several years. What should I do ?
I am using Visual Studio for Mac Community edition, version 8.2.3 (build 16)

I opened the project in VS 2017 on Windows 10. I uninstalled Newtonsoft.json, and reinstalled it. Everything seems to work (on Windows). I guess VS for Mac isn't pulling its weight.
I've suddenly started getting the above error when I create breakpoints in my code.
This appears in a dialog box, and when I OK the dialog box, the app sticks on the breakpoint in question and doesn't proceed. If I delete the breakpoint, the app still sticks on the breakpointed line.
The only thing I've changed is to update my FreshMvvm package (it's a Xamarin.Forms app), which brings in a load of .net standard libraries and uses Rx to create weak event bindings.
This is killing my development - any known cause/solution? I see this thread has previously been posted -but no solution.
This is on Visual Studio for Mac, and the app is on an Android device.

Redth's Addins 1.0.9
I just did a stable update of VS Mac Community Edition this morning. The current version shown is 7.2 (build 636). I added the entire About Details below. I'm not sure what specific version I upgraded from, but it was the most recent version before this as I stay up to date.
After doing the upgrade, which worked without displaying an error, I get this message when opening an iOS solution:
Error while trying to load the project '/path/to/project.csproj'. The
type initializer for 'MonoDevelop.CSharp.Project.CSharpProject' threw
an exception.
After dismissing that message, I get another error message with a list of this same error message:
The type initializer for
'MonoDevlop.ide.TypeSystem.MonoDevelopWorkspace' threw an exception.
I did a reboot of the machine, and I still see the error. My next step is to do a complete uninstall/reinstall, but before I do, can someone recommend a less time-consuming approach for diagnosing and fixing this error?

Ensure that you have MFractor extension 'Updated' or Uninstalled. That work for me.
Check:
Visual Studio Community Menu (Top) -> Extensions.... -> Upgrades Tab
Open Extension Editor
Check Upgrades (I remove the extension)
