I am using Visual Studio Professional 2019 and MATLAB 2020b. I was trying to run the following example code but receivng the exception that "Unable to cast COM object of type 'MLApp.MLAppClass' to interface type 'MLApp.DIMLApp". Does anyone know why? Thanks.
System.InvalidCastException: 'Unable to cast COM object of type 'MLApp.MLAppClass' to interface type 'MLApp.DIMLApp'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{669CEC93-6E22-11CF-A4D6-00A024583C19}' failed due to the following error: Unspecified error (0x80004005 (E_FAIL)).'
