MSBuild optional WithProperty

[nick5454]

I have a MSBuild statement, but for WithProperty I only want to add 2 flags if isAndroid variable is true.

Something like .WithProperty(test => IsAndroid == true, "AndroidBuildApplicationPackage", true)

Is this possible, actual code is below:

MSBuild(BuildParameters.SolutionFile.ToString(), configurator => configurator
    .SetConfiguration(BuildParameters.Configuration)
    .WithProperty("Platform", BuildParameters.Platform)
    .SetVerbosity(Verbosity.Normal)
    .WithProperty("BuildIpa", "true")
    //.WithProperty("AndroidBuildApplicationPackage", "true")
    //.WithProperty("Project", "appname.Android")
    .WithProperty("CodesignKey",  BuildParameters.CertTypes[BranchProject].IOSTeam)
    .WithProperty("CodesignProvision", provisionType) 
    .WithProperty("MtouchNoSymbolStrip", "false")
    .WithProperty("ArchiveOnBuild", "true")
    .WithLogger(
        Context.Tools.Resolve("MSBuild.ExtensionPack.Loggers.dll").FullPath,
        "XmlFileLogger",
        $"logfile=\"{BuildParameters.LogPath}\";verbosity=Detailed;encoding=UTF-8"
    )
);

There's nothing built-in at the moment that would give you a predicate to decide to add (or not) a property.

Is there any value of AndroidBuildApplicationPackage that would have the same effect as not having the property at all? e.g. false? If so, you could do something easy such as:

.WithProperty("AndroidBuildApplicationPackage", isAndroid ? "false" : "true")

You can see a similar example here.

Otherwise, you'd need to create an instance of MSBuildSettings, call (or not call) WithProperty based on the condition/variable and then use the MSBuild overload that takes an instance of MSBuildSettings.

e.g.

var settings = new MSBuildSettings();
settings.WithProperty("Platform", BuildParameters.Platform);
// etc.

if (isAndroid)
{
    settings.WithProperty("AndroidBuildApplicationPackage", "true");
}

MSBuild(BuildParameters.SolutionFile.ToString(), settings);

Silly me, I wasn't sure if by the presence of the flag that would change anything
