Xamarin Android app build fails on Windows 10 with GetAdditionalResourcesFromAssemblies throwing an exception (GenerateBuildSessionId in case of iOS)

[srikcgaa2]

Steps to Reproduce

1. On a Windows 10 machine, ensure the group policy "System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing" is set to "Enabled"
2. Create a new Xamarin Android application in Visual Studio 2015 Professional Update 3. Sample project attached with this issue.
3. Build the project

Expected Behavior

Build should be successful

Actual Behavior

Build fails due to a crash with GetAdditionalResourcesFromAssemblies step throwing an InvalidOperationException. If we create a new Xamarin iOS Application instead of Android, the failure occurs from GenerateBuildSessionId step

We have also tried to use the latest and greatest Xamarin Android and Xamarin iOS and has the same issue

[BBrelandARHS]

Same thing happening to me as well.

[cyberjetx]

Still broken in 2019. Can we please get a fix in. Deleting the key at
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy

NOR disabling
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy]
"Enabled"=dword:00000001 -> dword:00000000

work at this time.

@jonathanpeppers This basically is making it so that our company cannot use Xamarin due to government requirements for IT. It seems for the most part that MD5 is used for the naming of cache directories, so there must be an alternative that doesn't use broken cryptographic algorithms.

I was trying to download source and take a look at it, but the /Prepare stage is failing to download the android files: (links work, so not sure why it would be failing)

@kealist I would just try the command again, it doesn't have a network retry yet, you can double-check that URL in a browser: https://dl.google.com/android/repository/android-2.3.3_r02.zip

There is also a video here if that is helpful: https://youtu.be/8qaQleb6Tbk

[kealist]

@jonathanpeppers Thank you. Watching video. Unfortunately it fails on those downloads even if retrying or using different consoles. I tried with MSbuild 15 and 16. I don't want to pollute this issue with off topic build issues. though

[igloo15]

I just wanted to add that we are also running into this problem recently. New security guidance at my company as mandated from government customers is to have this FIPS policy enabled. There is no way around it so now we are quickly becoming unable to build Xamarin projects.

I hope this is fixed soon surprised this has taken so long to get on people's radar considering it was reported over a year ago.
