ArcGIS Pro CoreHost standalone Program Issue

gaofangwan

Hi Everyone,

I installed ArcGIS Pro 3.5 and then created a program with "ArcGIS Pro CoreHost application" template in Visual Studio 2022, and added little number line of code to open a FileGDB after Host.Initialize().

When Debuging it, it throw exception: "Unhandled exception: System.DllNotFoundException: Unable to load DLL 'CoreInterop.dll' or one of its dependencies: The specified procedure could not be found. (0x8007007F)"

And I have check that "C:\Program Files\ArcGIS\Pro\bin" have been added to the PATH System Environment Variable as here suggested.

If anyone know why? Please tell me how to solve it , thanks.

Are ArcGIS.Core.dll & ArcGIS.CoreHost.dll set to `Copy Local: Yes`?

If this doesn't work, please zip your project and post it in the thread so that we can download it for further investigation.

@Aashis is correct, but if you want to use the assemblies in your ArcGIS Pro / bin folder you can model your code using this sample: arcgis-pro-sdk-community-samples/CoreHost/CoreHostResolveAssembly at master · Esri/arcgis-pro-sdk-co...

The sample is using this code snippet to resolve the assembly path when the assembly is being loaded:

// Resolve ArcGIS Pro assemblies.
AppDomain currentDomain = AppDomain.CurrentDomain;
currentDomain.AssemblyResolve += new ResolveEventHandler(ResolveProAssemblyPath);

// Perform all your CoreHost tasks (API calls) in a method
// instead of in the Main method (you can't use the PRO API from within Main):
try
{
  PerformCoreHostTask(args);
}
