Cryptographic failure in WPF Reports v0.4 alpha

Question

I just downloaded the WPF Reports v0.4 alpha

When I build the project in VS 2008 I got the following error.

Cryptographic failure while signing assembly ' \CodeReason.Reports\obj\Debug
   \CodeReason.Reports.dll' -- 'Access is denied. ' CodeReason.Reports.VS2008

What is this error mean and how can I resolve this?

Answer 1

This can happen on Vista/Windows 7 when your account does not have permissions to he MachineKeys directory.

Just grant your user full control to folder %ALLUSERSPROFILE%\Application Data\Microsoft\Crypto\RSA\MachineKeys
