nuget packages
a) 2.3.0-py35-dotnet
b) python 3.5.4 (64 bit).

I was able to get install both nuget packages. This pythondotnet package seems to look for a python35.dll, So I had to install 3.5.4. This is a 64 bit project targetting .NET 4.5

I set the path variables both PythonHome and PythonPath.

The code just abruptly exits at the Py.GIL() line, I tried looking at nuget issues here but no luck.

Code Snipped below

        PythonEngine.PythonHome = @"..\..\..\..\packages\Python.3.6.2\tools\";
        PythonEngine.PythonPath = @"..\..\..\..\packages\Python.3.6.2\tools\";
       
        using (Py.GIL())   ----> code Exits here with error code 3.

If I debug the PythonEngine variable, I see that it has the correct path and picks up the correct version and there is a error message under delegatemanager, which says delegate manager has not been initialized.
I tried to use the PythonEngine.Initialize() method and the progam Exits.
What could the issue be here ?

Thanks

@user015 you need to pick 64-bit of python.runtime.dll from nuget installation manually:

my bad, I pasted a older copy. I am using 3.5.4 as shown below.

          PythonEngine.PythonHome = @"..\..\..\..\packages\Python.3.5.4\tools";
        PythonEngine.PythonPath = @"..\..\..\..\packages\Python.3.5.4\tools";

As I wrote earlier, the error I see when I debug PythonEngine is this

base {System.SystemException} = {"DelegateManager has not yet been initialized using Python.Runtime.PythonEngine.Initialize()."}

OK nuget package does not seem like a good option now. Also the nuget package for pythonnet seems to look for older version of python3.5.5 (python35.dll) as well. I was looking at this for distribution purposes, will go back to the regular setup. Thanks for all your help @denfromufa.

The latest versions of NuGet package now work with any supported Python version.
