Code analysis error CA0055 with a project upgraded to .NET Framework 4.5

I have a Visual Studio solution that was upgraded to use .NET Framework 4.5. It was working fine until I started getting the following error(s) running Code Analysis as part of the build:

CA0052 : No targets were selected

CA0055 : Could not load D:\dev\MySolution\MyProject\bin\Release\MyProject.exe. The following error was encountered while reading module 'System.Xml': Could not resolve type reference: [mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]System.Runtime.CompilerServices.IAsyncStateMachine

That seemed odd, as I confirmed that the application did have an assembly reference to System.Xml. I even tried re-adding the reference but that made no difference. The interesting thing is that the type (IAsyncStateMachine) is new in .NET 4.5, even though it is included in mscorlib Version 4.0.0.0. That’s because 4.5 is an in-place upgrade.

I did notice that you do get separate copies of the reference assemblies located in C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework. Reflecting on the mscorlib.dll assembly in the v4.0 folder showed it did NOT have IAsyncStateMachine, but the one in the v4.5 folder did. Could that be relevant?

Opening up the .csproj file, I discovered that another assembly reference suspiciously had the following HintPath defined

<Reference Include="System.Web">

  <HintPath>C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Web.dll</HintPath>

</Reference>

Re-adding this reference, resulted in Visual Studio changing it to just this:

<Reference Include="System.Web" />

And then re-building the solution with Code Analysis enabled was successful.

Aussie Toilets–Featured WP8 store app on 2nd July

In it’s 2 and a bit year history, this is the first time I’ve ever seen Aussie Toilets listed as a featured app in the Windows Phone 8 Store!

It’s one of the featured apps for 2nd July 2013. Nice! 😀

Winter 2013

It’s getting cold in Adelaide – the middle of June, and the leaves are turning yellow and red on some of the trees in our garden. The jonquils are blooming, and the daffodils won’t be far behind.

We’ve got a great crop of mandarins and lemonades. Been enjoying the mandies with lunches and juiced a couple of bucket loads of lemonades already.

The tangelo has a few more fruit this year, and the new lime tree also has a couple already (though it obviously isn’t liking the cold as it’s lost most of it’s leaves. I hope they grow back in spring).

It’s been pretty wet the last few weeks, so there’s some interesting mushrooms growing in the garden mulch
