Fix building of csproj samples directly

[PureWeen]

Description of Change

• Add CI step that builds singleproject.csproj and the two net6 sample projects to make sure they don't break
• updated readme with some workarounds related to Android simulator
• Added cake targets for building and deploying android/ios samples
• "SAMPLE-ANDROID"
• "Sample-IOS"

Works on my machine! I followed the standard steps and Android launches in the emulator! I'll try Mac next but this is already huge!

For iOS I ran:

./bin/dotnet/dotnet build src/Controls/samples/Controls.Sample.iOS/Maui.Controls.Sample.iOS-net6.csproj -t:Run

And got this error:

  Failed to launch the simulator: Could not find file "/Users/eilonlipton/GitHub/maui/src/Controls/samples/Controls.Sample.iOS/bin/Debug/net6.0-ios/iossimulator-x64/Maui.Controls.Sample.iOS.app/Maui.Controls.Sample.iOS"

And for MacCatalyst I ran:

./bin/dotnet/dotnet build src/Controls/samples/Controls.Sample.MacCatalyst/Maui.Controls.Sample.MacCatalyst-net6.csproj -t:Run

And got this error:

nction=_LSOpenStuffCallLocal}

[/Users/eilonlipton/GitHub/maui/src/Controls/samples/Controls.Sample.MacCatalyst/Maui.Controls.Sample.MacCatalyst-net6.csproj]

And I tried another command line to launch MacCatalyst:

dotnet build src/Controls/samples/Controls.Sample.MacCatalyst/Maui.Controls.Sample.MacCatalyst-net6.csproj -t:Run -p:Configuration=Debug -p:TargetFramework=net6.0-maccatalyst --no-restore

And got the same error:

[/Users/eilonlipton/GitHub/maui/src/Controls/samples/Controls.Sample.MacCatalyst/Maui.Controls.Sample.MacCatalyst-net6.csproj]

Is there a different command line I should use for iOS and MacCatalyst?

[PureWeen]

/azp run

[azure-pipelines]

Azure Pipelines successfully started running 1 pipeline(s).

@Eilon I'm not sure on those exceptions. I'm seeing the same thing

@jonathanpeppers @Redth @mattleibow ?

[Redth]

Unfortunately these are intermittent it seems on catalyst. @dalexsoto any insights yet into these?

[jonathanpeppers]

These projects are all in Microsoft.Maui-net6.sln, so they are already getting built. We shouldn't need to build them twice?

[PureWeen]

The main reason to build them is to verify that they are able to build not via the SLN file

For example right now on our main branch if you run
dotnet build any_of_these_projects.csproj

it fails.

So the purpose of adding all of these is to make sure that they stay working and that new PRs don't break them

[jonathanpeppers]

This Condition is starting to get out of hand, can we invert the condition here so it will be a lot shorter? Check for the legacy Xamarin .sln or something?

[PureWeen]

Probably, but since it's a weird hack either way I'd rather not mess with it. I'll probably do it wrong a few times while trying to invert it :-) Ideally we can just delete this whole thing in a few weeks and all of our legacy slns?!?

[PureWeen]

I merged this one for now so we can at least fix the builds

I created an issue here for @Eilon 's comments

#1175

If anyone has any insights why ios and maccatalyst aren't launching
