VB.NET CODE 2013 migrate to 2014 AUTOCAD

[amyyoyo1]

Hi All,

I am trying to migrate the vb.net code from 2013 to 2014 autocad. I change all the reference paths and rebuilded the code, no error show up.

but when I try to load the dll file into the autocad 2014 a error message show up. 

Cannot load assembly. Error details: System.IO.FileLoadException: Could not load file or assembly 'file:///P:\ACAD2014\VB NET\SplashScreen_jmv\SplashScreen_jmv\bin\Debug\SplashScreen.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
File name: 'file:///P:\ACAD2014\VB NET\SplashScreen_jmv\SplashScreen_jmv\bin\Debug\SplashScreen.dll' ---> System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

I try to see if it's becasue the file was lock but it's seem like the file is fine and it's runing fine in 2013 autocad.

I hope someone can help me out of this. Thank you.

You can't load a dll from a network location. I'd guess 2013 you are loading locally and 2014 from a network location.
