Description Jon Douglas [MSFT] 2014-12-19 11:44:20 UTC
*Description

It seems that when using the <AndroidUseLatestPlatformSdk>true</AndroidUseLatestPlatformSdk> tag, it confuses Nuget as to what actual TargetFrameworkVersion it is using and therefore cannot install packages correctly.

Given the simple reproduction:

Create a new File -> New Android Project.

Have Android API 21 installed which would be the UseLatestPlatformSDK in this case.

Attempt to install any Android.Support library targeted for 21.0.X.

Nuget will error because it doesn't know what TargetFrameworkVersion it's using as we only have the following in the .csproj:

   <TargetFrameworkVersion>
    </TargetFrameworkVersion>

To fix this, we must use a specific Android version so our TargetFrameworkVersion will be set and Nuget can figure it out:

<TargetFrameworkVersion>v5.0</TargetFrameworkVersion>

Wat?

$(AndroidUseLatestPlatformSdk) doesn't mean you can completely omit $(TargetFrameworkVersion). It just means that we'll attempt to *update* the $(TargetFrameworkVersion) during the build process.

(It never occurred to me that the value *could* be omitted. What are you doing to create such a situation?!)

That said, the probable fix is that we need to execute _SetLatestTargetFrameworkVersion earlier.

Please provide a complete test project and diagnostic build output.
