Xamarin.Forms.2.3.4.247 update : project won't build
USMember ✭✭
Hi,
I just updated Xamarin.Forms to version 2.3.4.247 as well as a couple of other packages, and I get this error, completely new for me:
...\portable-win+net45+wp80+win81+wpa81+MonoAndroid10+Xamarin.iOS10+xamarinmac20\Xamarin.Forms.targets(68,4): error MSB4064: The "DebugType" parameter is not supported by the "XamlCTask" task. Verify the parameter exists on the task, and it is a settable public instance property.
...\portable-win+net45+wp80+win81+wpa81+MonoAndroid10+Xamarin.iOS10+xamarinmac20\Xamarin.Forms.targets(62,3): error MSB4063: The "XamlCTask" task could not be initialized with its input parameters.
Any idea of possible cause of this error?
The project was initially working with Xamarin.Forms 2.3.1.114, it is a PCL project, not using XMAL.
Thank you.

I have the same problem too... can anyone help us?
Same problem here. My project do not have any XAML
I was unable to run my app with the previous version of Xamarin.Forms, so I updated, and this error is showing up for me too.
Solved for me: Restarted my Visual Studio and rebuilt.
Restarting and rebuilding hasn't worked for me. I'm seeing this error on both PC and Mac versions of Visual Studio, running on code that I know compiled and ran without issue yesterday. I even tried deleting the entire project, pulling a fresh version of the master branch, uninstalled and reinstalled Visual Studio - still getting that error.
What did allow me to get past it temporarily was editing the
Xamarin.Forms.targetsfile, which for me lived in:packages\Xamarin.Forms.2.3.4.247\build\portable-win+net45+wp80+win81+wpa81+MonoAndroid10+Xamarin.iOS10+xamarinmac20and removed the
DebugType = "$(DebugType)"line.This obviously isn't a proper fix, though.
@akadam
below steps work for me
step1:
you have to maintain same xamarin.forms version in pcl, android and ios.
step2:
delete the bin and obj files in pcl, android and ios. then rebuild the solution
Same problem here. some one get a solution for this problem?
first help: downgrade Xamarin.Forms to 2.3.4.231 and it work again
I'm also having the same problem. Please can anyone help me out ?
Thank you all for you comments.

Checked that all the project reference Xamarin.Forms V 2.3.4.247
Deleted every bin and obj folders in every project.
Restarted Visual studio then try to rebuild
=> still getting the same error during PCL project compilation
I'll try now to downgrade Xamarin.Forms to previous versions and try again.
Hello.
Closing visual studio and deleting ALL "bin" and "obj" folders has solved the problem for me.
I'm using a Shared Project.
Best regard,
Marco
I have PCL and try:
Nothing work for me, another action to do?
Same here
It's only the release build for me that won't build.
Debug builds fine, and runs on the emulator at least - not tested on a device yet
VS 2017 Enterprise
This is probably the only solution that will work.
My guess is that someone has compiled this package in a development environment and forgot to take their dev code out of the .targets file when publishing to nuget. This will probably only affect people who use XAMLC
my advise is to follow the steps outlined above and wait for an updated nuget to be released, which would replace the .targets file anyway, so no permanent damage
@ChrisRzepa that fixed the issue for me, thank you
@JKay I didn't want to modify the .targets file but I understand now that it is safe to do so, thank you for the explaination !!
Looks like they've patched it (hoping it's the same thing). Just have to wait for it to be released: https://github.com/xamarin/Xamarin.Forms/commit/f01cf880403f649cf6d6ccc71d930eae646bc698
This did it for me. The issue was happening while developing in Android. However I did a quick build to iOS then came back to Android. It got resolved only after deleting "bin" and "obj" from both iOS and Android
Worked for me.
Closing visual studio and deleting ALL "bin" and "obj" folders has solved the problem for me as well. Make sure you close all instances of VS. I have a habit of having 2-3 instances up at the same time!
Now if only I could get past the "The file "obj\Debug\android\bin\packaged_resources" does not exist." issue!
I did a full git clean (i.e. delete all NuGet packages, bin, and obj folders) and the problem doesn't go away. I'm getting two errors and it has halted work.

All the dependency spaghetti in Xamarin Forms means that it's absolute pot luck as to whether a given project will compile for a given platform on any given day.
I wiped everything again, and did a Consolidate inside NuGet for the solution to make sure all my platforms have the same versions of Xamarin Forms etc. and I'm still getting this problem. Thanks Xamarin. Yet again, I find myself bashing my head against the wall just trying to get this stuff to compile.
After trying all the workarounds suggested in this thread, I believe that this is the one that works.
This worked.
What did allow me to get past it temporarily was editing the Xamarin.Forms.targets file, which for me lived in:
packages\Xamarin.Forms.2.3.4.247\build\portable-win+net45+wp80+win81+wpa81+MonoAndroid10+Xamarin.iOS10+xamarinmac20
and removed the DebugType = "$(DebugType)" line.
There has been a fix checked into github for this issue:
https://github.com/xamarin/Xamarin.Forms/commit/f01cf880403f649cf6d6ccc71d930eae646bc698
but is yet to be packaged for nuget. Probably in next build
First Step : delete all bin/ obj folders
Second : Restart VS
if problem not solved
open
packages\Xamarin.Forms.2.3.4.247\build\portable-win+net45+wp80+win81+wpa81+MonoAndroid10+Xamarin.iOS10+xamarinmac20\Xamarin.Forms.targets
file remove blow lines
DebugType = "$(DebugType)"

Well, removing the DebugType entry works for release iOS build, but not for debugging in simulator. "XamlCTask" task failed unexpectedly. I also deleted all bin and obj directories as well.
I gotta say... this xamarin thing has cost me probably close to $200k in lost production time over the last three years, not counting the costs of very expensive licensing up until recently. One thing after another, you just can't win with these guys. They're sloppy, and oftentimes unhelpful. Personally, I hope MS fires them all over time, and replaces them with competent people who actually know how to put together a PROFESSIONAL development environment.
I went back over to using crappy xamarin studio. While it has a whole host of other annoying issues, I can at least compile and (for the most part) debug.
Frustrating issue. Obliterating output paths didn't do the trick, but closing VS (macOS) and then deleting all bin/obj directories (I did a directory search of my entire source repo, so unsure if it found something other people were not when manually deleting) and then re-opened and archived for publishing (is all I needed to do) and it worked.
@Vaka.GopiNadhReddy Solution of keeping the same versions for Xamarin.Forms along all projects worked for me too.
works for me
I had to make sure that both iOS and Android apps in my project had the same version of Xamarin Forms to fix this.
I just renammed an Image in Resource folder in Android Project and i got this error. WTF!
But Restarting VS did the work for me.
I rollback Xamarin.Forms to version 2.3.4.231, then the error is gone.
Waste too much time on it.
Sometimes it helps me to change Solution Platform from Any CPU to x64 or x86, recompile project, and then back to Any CPU.
exit VS, delete all obj and bin folders, run VS and build. That fixed it for me.
Deleting my repo and re-cloning did the trick for me.
this worked thanks ,
what i did was Deleted the obj and the bin folder and then removed the line above clean - > build
everything worked fine and then re added the line above
In my case:
1. Uninstall Xamarin.Forms
2. Restart VS
3. Install Xamarin.Forms.
4. Build and Work
I had the same issue too, In my case I have had updated only the App.Android assembly, forgetting the PCL's one.. my bad
Updating Visual Studio (for Mac) to latest build ( Version 7.0.1 (build 24)) solved the issue for me.
I hope it helps.
