Error in Forms when creating simple form in c sharp

Question

Hi
I've created a very simple Csharp form with two textboxes and one press button. It is linked to a fortran DLL (Salford Compiler)
When I compile and run the program the first time it all works well. But when I save the file  and quit VS 2013
and then restart and reload the program I get this funny error when I try to view the form again.
Warning 1 The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))  0 0 
I've tried deleting the Temporary asp.net files as suggested in one forum but to no avail. Any help much appreciated

Hi ProfTC,
By researching, I found this thread in StackOverFlow, which has solved this problem.

The answer is below:
Depending on if your are running X64 you might need to clean up a couple more spots.  Just cleaning up my user directory was not enough.
%TEMP%\Temporary ASP.NET Files
C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files
This list will grow as if you have other versions of the framework installed.
So , you could clear these ASP.NET files in more spots.
If you still have problems, you could feel free to let me know,
Or if your project is related to ASP.Net, you could post your issue to the ASP.Net forum for better supports.
