I'm getting a odd error when using v3.2.3 of Razor. The below method is throwing the error:
"Unable to compile template. The predefined type 'System.Tuple' is defined in multiple assemblies in the global alias; using definition from 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll'
Other compilation errors may have occurred. Check the Errors property for more information."
There is also this error in the errors property on the exception:
"The type 'System.Tuple' exists in both 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' and 'c:\Program Files (x86)\IIS Express\Microsoft.VisualStudio.Utilities.Internal.Net35.dll'"
Our project was recently upgraded to .Net v4.6.1 so I'm sure this is what has caused the issue, however I don't know how I can resolve it.
For this error, it seems you reference the “Tuple” dll in multiple assemblies. I suggest you search “Ssytem.Tuple” in the Solution explorer, and then remove the repeated dll.

public string Build(string ressourceName, object model) { return Razor.Resolve(ressourceName, model).Run(new ExecuteContext()); }There is also this error in the errors property on the exception:
"The type 'System.Tuple' exists in both 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' and 'c:\Program Files (x86)\IIS Express\Microsoft.VisualStudio.Utilities.Internal.Net35.dll'"

Does anyone have any ideas on how I can fix this?
