ArcGIS Pro CoreHost standalone Program Issue

Question

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.

You can always try kicking the box if that doesn't work.  For me, Wolf's suggestion offers a more cost effective, not to mention logical, solution.

Hi @Wolf  and @Aashis , I have solved the issue by re-installing Windows operation system and ArcGIS Pro.

@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-community-samples

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);
}
