Microsoft.Bcl.Async nags about missing "The type 'AnnouncementClient' is required here and is unavailable."

The project is built to .net 4.6 so it should not do anything. At least I was under the impression it shouldn't do anything.

But to my suprise this ended up in my project file:

<When Condition="$(TargetFrameworkIdentifier) == '.NETFramework' And
 ($(TargetFrameworkVersion) == 'v4.0' Or $(TargetFrameworkVersion) == 'v4.5' Or 
  $(TargetFrameworkVersion) == 'v4.5.1' Or $(TargetFrameworkVersion) == 'v4.5.2' Or
  $(TargetFrameworkVersion) == 'v4.5.3' Or $(TargetFrameworkVersion) == 'v4.6')">
  <ItemGroup>
    <Reference Include="Microsoft.Threading.Tasks.Extensions.Desktop">
      <HintPath>..\..\packages\Microsoft.Bcl.Async\lib\net40\Microsoft.Threading.Tasks.Extensions.Desktop.dll</HintPath>
      <Private>True</Private>
      <Paket>True</Paket>
    </Reference>
      yadda yadda yadda
  </itemGroup>
</when>

why does this reference get added to the project for 4.6 when the package is obviously meant for .net4.

I don't know if this is a paket issue, but I thought I'd ask here anyway.

ps. I'm so fed up with these Bcl packages...

net40 means .NET 4.0 and above. at least if there is no other net folder.

Try with Nuget - it will install the same dlls.

Alright I believe you. 😄 I have to manually remove this ref from the project to get it to build.

I've recently started getting the same error message actually. For example this project currently builds as expected, but it will fail as soon as I paket update.

For the record, and reproducing our private discussion with @forki, the problem more likely has to do with a bug in paket when resolving the dependency graph for AWSSDK.Core, which has the following dependency tree

    <dependencies>
      <group targetFramework=".NETFramework4.5" />
      <group targetFramework=".NETPortable0.0-net45+netcore45+wpa81+wp8+MonoAndroid10+xamarinios10+MonoTouch10">
        <dependency id="Microsoft.Net.Http" version="2.2.29" />
        <dependency id="PCLStorage" version="1.0.2" />
        <dependency id="PCLCrypto" version="1.0.2.15130" />
      </group>
    </dependencies>

which however is resolved to the following paket.lock:

 AWSSDK.Core (3.1.5.3)
      Microsoft.Net.Http (>= 2.2.29) - framework: >= net45, portable-net45+win8+wp8+wpa81
      PCLCrypto (>= 1.0.2.15130) - framework: >= net45, portable-net45+win8+wp8+wpa81
      PCLStorage (>= 1.0.2) - framework: >= net45, portable-net45+win8+wp8+wpa81
