SetValue: Can not convert System.ReadOnlySpan to type 'Xamarin.Forms.Color'
USMember ✭✭✭
Getting this weird error(s) after upgrading Visual Studio yesterday:
[0:] SetValue: Can not convert System.ReadOnlySpan`1[[System.Char, mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]] to type 'Xamarin.Forms.Color'
Any idea what that is all about?
thanks

Someone else had an goofy error they posted, after upgrading.
Then they upgraded to XamForms 3 and said it went away.
Not so sure that's a viable route for everyone.
But you can make a copy of your solution directory then try it.5 -

Tried updating to Xamarin Forms 3. It failed until I manually removed references to the previous version of Forms from the Android csproj file. Again, this is Enterprise, going to try Prof next.

VS Prof: rebuild (fails), then build (success), then run. App runs in Prof now. Programming is fun.

You need to upgrade to the latest xamarin forms 3
Also, you can't trust Build/Clean Solution in VS (I think it is a no-op). I wrote a script like:
rd /s /q C:\your path goes here\Android\bin
rd /s /q C:\your path goes here\Android\obj
rd /s /q C:\your path goes here\SharedMobile\bin
rd /s /q C:\your path goes here\SharedMobile\obj0

Upgrade the 3 failed for me the first try, but I will try, try, try again.
[I have noticed that Visual Studio Enterprise is way smarter at upgrading packages, but only had the trial.]
thanks,
will let you know how it goes (tomorrow)
I can use my trial version of Visual Studio Enterprise to run the project okay. Well, after much manual cleaning/rebuilding/rebooting.
Project does not run in Visual Studio Professional.
Guess if you want to do Xamarin development, you just got to pay more. A lot more.
Glad you're good again. But get out of those emulators as fast as you can. Go down to your cell store or Sams's club etc. and buy a $50 Android tablet... Your phone carrier may just give it to you free if you activate a line of service on it - which you'll want to properly test your app's connectivity and functionality anyway.
As for everything else... Well, yeah. Welcome to coding and Visual Studio.

I have an Android phone I test with. I like the emulator for most testing, runs nice and fast, plus full sized keyboard.
I like to use Vyser to remote operate the physical device for the same reason. Its basically like a VNC connection to a remote computer. You get to use your mouse and keyboard to operate a real device, and see the real device on your PC screen, which is great for screenshots etc.
