Hi all,
I am trying to deploy a MATLAB class that inherits from MATLAB Handle Class to a .NET Framework 4.8 project. Most of the steps I have replicated from this guide using the MATLAB 2024a complier and the MATLAB 2024a Runtime.
So far I get a successful compliation on Visual Studio 2022 but upon running I get the following Exception:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Unhandled Exception: System.TypeInitializationException: The type initializer for 'MathWorks.MATLAB.Runtime.MATLABRuntime' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'libMatlabCppSharedLib24_1': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Press any key to continue . . .
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
It appears to be suggesting that it is unable to locate the 'libMatlabCppSharedLib24_1'. I have checked in <MATLABROOT>/MATLAB Runtime/R2024a/runtime/win64/ and can actually find the libMatlabCppSharedLib24_1.dll in question.
I have referenced the MathWorks.MATLAB.Runtime.dll and MathWorks.MATLAB.Types.dll from the <MATLABROOT>/MATLAB Runtime/R2024a/extern/dotnet/netstandard2.0/ directory. Is there something else I need to make sure I need to configure or double check?
Would appreciate any pointers or improvements to this post.

I have found my solution and hopefully it helps anyone else who comes across this problem.
The problem was in the PATH environment variable. I have both 2023b and 2024a installed, and although 2024a variables were higher in the list, the .NET application kept running the 2023b matlab runtime instead. I removed the 2023b runtime path variable and was able to get past the error above.
