I have a new .Net 4.5.2 (verified that this is the target platform). Web API Application (in VS 2015). I referenced System.Net.Http, and, as you see, version 4.0.0.0:
In my Filter / Attribute, I try to reference HttpRequestMessagewhich is in the namespace System.Net.Http(I have the correct use at the top of my file), but I get a message saying
The type "HttpRequestMessage" is defined in an assembly that is not referenced. You must add a reference to the assembly 'System.Net.Http, Version = 4.0.0.0, Culture = neutral, PublicKeyToken = b03f5f7f11d50a3a'
And although I cannot reference this class, I can go to it in Object Exploerer (I assume that it uses an XML file with the same name next to the .dll).
I tried (edited: like a normal VS restart and rebuild, etc.):
- Removing and re-adding a link (both from the Framework and from the Extension - although I'm sure it was a version of the Framework, I was getting desparate)
- Installing from Nuget and linking to the version in my local package folder, which apparently just goes back to the system-wide version by default.
- Reinstalling all my dependencies in Nuget PM with:
update-package -reinstall -ignoreDependencies - Adding an assembly manually to web.config Adding an assembly manually to a .csproj file
