I have a code that calls a .NET 4.0 DLL using NET.AddAssembly. This code works fine inside MATLAB. I am using MATLAB Compiler 4.14 to build a console application from the aforementioned code. I receive the following error at runtime

 This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

This issue occurs when the compiled executable tries to load the assembly with .NET 2.0 framework by default. In order to overcome this issue, create a CONFIG file. For example, if your executable is 'foo.exe', create a file called 'foo.exe.config'. Add the following contents to that file

<configuration>
      <startup useLegacyV2RuntimeActivationPolicy="true">
          <supportedRuntime version="v4.0"/>
          <supportedRuntime version="v2.0.50727"/>
      </startup>
</configuration>
