I thought adding the allow partially trusted callers to the assembler would work but I still get a security exception assembly does not allow partially trusted callers.

I'm fairly new to C# and .NET. I'm developing a windows application that opens up a open file dialog and chooses an excel file to grab data from for the application.

Security Exception, assembly does allow partially trusted callers

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
