.NET 4.5.2 - Build contains projects using unsupported .NET frameworks

Hi, I'm getting this error message that .NET 4.5.2 is unsupported.

Here is the targetFramework from my Web.Config file:

<system.web>
    <authentication mode="None" />
    <compilation debug="true" strict="false" explicit="true" targetFramework="4.5.2">
...
    </compilation>
    <httpRuntime targetFramework="4.5.2" />
...
</system.web>

According to this post, 4.5.2 is supported but maybe I'm missing something - http://blog.appharbor.com/2014/08/28/windows-server-2012-r2-iis-8-5-websockets-and-net-4-5-2

Thanks,

Wayne

   Here are all of the warnings from my build log:

   It looks like switching to .NET 4.5.1 did the trick.

   Could you confirm if .NET 4.5.2 is supposed to be supported and if so, what can I do to target it?

   Thanks,

   -Wayne

   Hi,

   It looks like you've configured it correctly, so this is a bit odd. Let me look further into this and get back to you asap!

   Best,

   We have the same issue with .NET 4.5.2. The compile/build actually appears to be fine, the issue is reported after build completed:

   "Build contains projects using unsupported .NET frameworks"

   Any idea what's going on there? Application is analytics.rowinginmotion.com

   Hi,

   This was unfortunately caused by a configuration issue that has prevent deploy engines from actually deploying the apps.

   The worker servers and build infrastructure will be swapped this weekend and the configuration hiccup will be resolved by that.

   Best,
   Rune
