Nightly Builds

[MAUIoxo]

Just wanted to ask if there are no new nightly builds anymore or if they are broke. The last couple of days, I could not see any nightly builds available

[nor0x]

no new nightly builds since Feb 16 according to their AZDO

New nightly just dropped

We have a new nightly! So it seems they resumed the nightly.

I updated my Nugets to the latest nightly and my project (Android+iOS) just refuses to build.

1>CSC : warning CS8785: Generator 'CodeBehindGenerator' failed to generate source. It will not contribute to the output and compilation errors may occur as a result. Exception was of type 'ArgumentNullException' with message 'Value cannot be null.

Just to note I've never tried nightly before so I'm not sure if I'm doing anything wrong.

I'm seeing this error now in my project after only upgrading to the latest release. I've been trying to find some tips on how to debug it. Unlike how you are getting it on the nightly build. I'm getting it from the 8.0.10 stable build.
