ASCOM.Alpaca.Components 2.0.8

ASCOM.Alpaca

A set of client tools to discover and access Alpaca devices. Written to .Net Standard 2.0 for maximum applicability.

This release supports the interface updates introduced in ASCOM Platform 7.

Please note that you will need to add this PropertyGroup to .NET projects that target Android in order for Alpaca discovery to work as expected:

    <PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">
        <UseNativeHttpHandler>false</UseNativeHttpHandler>
    </PropertyGroup>

This may also be the case for projects that target IOS, but has not yet been confirmed.

Release 2.0.8

Release 2.0.2
