"MM0000: Unexpected error" when an invalid character is used in the Assembly Name: "Hello, Mac" #5552

Open bvanrijn opened 5 years ago

bvanrijn commented 5 years ago

Steps to Reproduce

  1. Attempt to follow https://docs.microsoft.com/en-us/xamarin/mac/get-started/hello-mac
  2. Try to build the resulting project.

Expected Behavior

The app builds without any errors and then running the app works as well.

Actual Behavior

Building the app fails with:

/Users/barend/Developer/CSharp/HelloMac/MMP: Error MM0000: Unexpected error - Please file a bug report at http://bugzilla.xamarin.com (MM0000) (HelloMac)

I found https://bugzilla.xamarin.com/show_bug.cgi?id=44697, which says:

That exception means we crashed inside mmp, which is never acceptable. With more information, we can get to the bottom of this.

I'm not entirely sure where I read this, but it seems that the culprit was the display name of the app. I had changed it to "Hello, Mac" (mind the comma) instead of "Hello_Mac" as is used in the tutorial.

Following the tutorial in record time, making sure not to change the display name, everything works!

I still think this error message should be updated.

Hello @bvanrijn!

Thank you so much for your report! You are completely right, we should do a better job when providing invalid assembly names into our tooling, I will make sure to mark this enhancement request as such.

Again, thank you for your report!

MM0000 or MT0000 are bugs (missing validations) since they do not provide an actionable description to solve the issue.

spouliot commented 5 years ago

This works fine in iOS (even if the name will be without a space and comma when using the project's wizard) and it's also a valid assembly name (as far as .net is concerned).

spouliot commented 5 years ago

Actually it works on iOS simulator but on device the AOT compiler is not happy.
