I installed the latest Microsoft Visual C++ 2015-2022 Restributable and still get the error.

Hi,

Is this error within Visual Studio, when trying to debug/start the app? Are you able to repro with a simple app created from our project template? 

NuGet Gallery | Esri.ArcGISRuntime.ProjectTemplates 200.8.0 or ArcGIS Maps SDK for .NET Project Templates - Visual Studio Marketplace

Thanks

I encountered the same problem. How can I solve it？

debug/start the app within Visual Studio is OK(windows 10), but can't start on other PC (windows 11 build 24H2)

Hi,

Have you installed the Visual C++ Redistributable for Visual Studio 2015-2022? (or included the redistributable with your installer)

Latest supported Visual C++ Redistributable downloads | Microsoft Learn

 

Do you have the libraries described in this topic in the correct location relative to the application? 

Deployment | ArcGIS Maps SDK for .NET | Esri Developer

 

Thanks

Hi,

Have you copied application from bin\release or used published content? You need to publish application from Visual Studio. Right click on project and select Publish menu item. Define publishing folder. After publishing copy publishing folder content. On other PC on startup you will be asked to download and install .NET version used in your application if it doesn't exist.
