ASCOM.Alpaca.Components 2.0.7

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.

Version History

• Reduced the delay between communications error retries from 1.0 second to 0.1 seconds.

Release 2.0.2

• Change the timeout used for Connected-GET, Connecting, Connect() and Disconnect() from the standard timeout to the establish communications timeout, which is usually shorter and facilitates quicker return to the client when the Alpaca device cannot be reached.
