Unhandled exception with newer dot net and CAS Policy

[mlt]

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Users\mlt\Downloads\PCScope1.18.12.27\DSO.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
File name: 'file:///C:\Users\mlt\Downloads\PCScope1.18.12.27\DSO.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.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

I was lazy to re-build the source, the quick workaround is to create a configuration file named PC Scope.exe.config next to exe with

<configuration>
  <runtime>
    <loadFromRemoteSources enabled="true" />
  </runtime>
</configuration>

Thank you very much for this finding. As I can see, this error is thrown only when you clicked at "About" command. Am I rigth? Or it being thrown at startup? I use AssemblyInfo to retrieve information about DSO.dll to display them in About pop-up window. This approach in the past caused some issues.

[mlt]

I did click About indeed. It seemed to be unresponsive so I clicked around. Perhaps I was thrown off by big white rectangle :-)

I'm not that familiar with dot net… can you use FileVersionInfo instead?

Also it seems I cannot change either resolution. I get "Error while setting parameters". I have DSO112A / Coral.

Another thing is it won't remember communication preference. After I disconnect, I have to set COM3 again before reconnecting otherwise I get

---------------------------
Error
---------------------------
Please set serial communication properly
---------------------------
OK   
---------------------------

It would be nice if it presumed defaults.

For your issues with Coral check DSO.dll wiki. Long story short : Coral has bugs in serial interface. It is not possible to reliable change device parameters while device is connected and sends buffer to serial interface. Workaround: Device -> Stop Capture
-> Manually change parameters to desired one
-> Device ->Start Capture -> Click "Refresh" button.
In order to keep information i will need to save some kind of config file and for sure this is something that I may do in future release. I will try to adres those issues in my spare time and i will draft a new release.
