VoteIf you're using VS 2012, you can change the target framework of the project by hand editing the file. For details, see: http://stackoverflow.com/a/2921868/65358
Once you target framework 4.5, you can reference 4.5 assemblies.
Note that VS 2012+ is required to target .NET 4.5, though.

0Thanks. I installed vs 2012 update 3 and made the manual changes. That lets me see and select the 4.5 assemblies in "Framework and References", but when I build the project I see this message; Project file contains ToolsVersion="4.5". This toolset is unknown or missing. You may be able to resolve this by installing the appropriate .NET Framework for this toolset. Treating the project as if it had ToolsVersion="4.0". I have version 4.5.50709 installed, I'm pretty sure it got installed with vs 2012. I do also have vs 2010 installed in this machine, not sure if that matters. Any ideas?Monday, August 05, 2013 5:14 AM![Question]()
VoteThanks for Reed’s help.
Hi Todd,
If we change the target Framework, we would change the platform toolset to a version that supports that Framework. To target the .NET Framework 4.5, we would use a compatible platform toolset “Visual Studio 2012 (v110)”.

VoteYou'll also need to set the platform to VS 2012, as Jack mentioned - With C++, the platform + the framework need to match, and for 4.5, you need both to be 2012's setup.

0The "Platform Toolset" has always been "Visual Studio 2012 (v110). I still get the error;
Project file contains ToolsVersion="4.5". This toolset is unknown or missing. You may be able to resolve this by installing the appropriate .NET Framework for this toolset. Treating the project as if it had ToolsVersion="4.0".
Whenever I build it. I'm not sure it's really building with 4.5 because I get the following error when I try to validate a SAML2 assertion signature;
SignatureDescription could not be created for the signature algorithm supplied.
The assertion was create by ADFS and the signature algorithm is SHA-256 which is not supported by .net 4.0. Searching around seems to indicate that message is what you get when .net 4.0 tries to validate a signature created with that algorithm.

VoteHi Todd,
Glad to receive your reply.
If possible, you could re-install .NET Framework 4.5, check it again.
You could download it from here:
http://www.microsoft.com/en-in/download/details.aspx?id=30653
If still no help, I’m afraid that we would check whether it supports it in this specific VC++ project. You could post this issue to the VC++ development forum here:

If there's any concern, please feel free to let me know.
