Can not create datatype in version 7.0.0

I just start to learn how to use the umbraco and I installed the umbraco 7.0.0 with assembly: 1.0.5073.23294 in a empty mvc 4 project via nuget. After login, I tried to create a data type with the render as checkbox list and then it notified me this error:

Failed to save data for data type id 0

The given key was not present in the dictionary.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.<>c__DisplayClass5.<ExecuteAsync>b__4()
   at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)

Is this a bug? Or I miss something during the setup? I only installed the Umbrac Cms Core Binaries and Umbraco Cms.

Can anyone help me on this? thanks!!
