C# Loaded Via WinBatch - Renci.SshNet.dll won't load.

[JTaylor]

The following code works fine in VS but when I try loading via WinBatch it tells me that it cannot load Renci.SshNet file or assembly because it cannot find the file.   I have tried using the full path but that didn't help in the reference.  Adding "using" statements for it doesn't help either.    Suggestions?

Thanks.

seems your not the only one....

The obvious question is where is the "Renci.SshNet.dll" file located on your system?  It either needs to be in the GAC or you need to use the "appbase" option to set the location of that DLL.  The MySQL installer places a copy of the "Mysql.Data.dll" in the GAC for you under the GAC_MSIL directory.

Another possibility is that you are not loading one of the "Renci.SshNet.dll" assembly's dependent assemblies.

[JTaylor]

It is in the GAC_MSIL.  I also copied it to the script directory to see if that helps.   I used the full path in the R.A.Add()  method.  I tried what you suggested and get a slight different error.   

UPDATE:   I am not sure what I have done differently other than I tried what you suggested with appbase and copied the Renci dll from the VS compile directory and replaced the one that I copied from the GAC_MSIL location.   Must be some important difference in the Renci file even though they seem to be the same version under properties.  It seems to be working now.  Thanks.

I built the "Renci.SshNet.dll" assembly,  dumped it into the scripts directory, added DirScript():"Renci.SshNet.dll" to the compile and set "appbase" to "DirScript()" with the ObjectClrOption function.  It worked first try. 

Next, I installed the "Renci.SshNet.dll" into the GAC using gacutil.exe, removed the DLL from the script's directory and then change the Add line to point to "Renci.SshNet.dll" file in the original release build directory and commented out the "ObjectClrOption('appbase', DirScript())" line from the script.  Again the script worked first try.

Methinks something went amock when you installed the DLL into the GAC.

[JTaylor]

May be.  I never installed that intentionally.   It was just there.   I went back and copied the version from GAC_MSIL to the script directory and error returns.   If I copy the one from VS studio back in, it works fine.   In any event, it is working so thanks again.

I used the latest GitHub source and compiled it using VS 2019.  The VS projects did not install the compiled assembly into the GAC so your version of the assembly must have gotten into the GAC by some mechanism other than simply building it with VS or you used a different source.
