Compilation error when trying to build report project in VS

Hi,

I have opened LedgerTransListAccount report project in Visual Studio in order to make one modification. After completing the changes, when I try to build the project, I am getting below error:

Error 1 Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401) C:\Program Files (x86)\MSBuild\Microsoft\DynamicsTools\Microsoft.Dynamics.Framework.Design.Reporting.Modeling.targets 103 6 LedgerTransListAccountReport

Does anyone have any idea how to resolve this issue. The version of Visual Studio is 2010 Premium and AX version is AX 2012 R2.

Thanks,

Baber.
