MapView does not exist in namespace http://schemas.esri.com/arcgis/runtime/2013

Hi Community,

I'm just trying to create an initial app from the available tutorials.

I'm utilizing VS 2022, Windows 11, I've installed ArcGIS_Maps_SDK_DotNet_200_7_0.vsix.

I've added the ESRI.ArcGISRuntime.WPF nuget package but the app is not recognizing MapView as a namespace. I read in older versions of the nuget package there were issues but that was years ago.

I'm guessing I'm missing another nuget package or I need some other install from .vsiz?

Thanks for any suggestions,

Carol

End goal is to utilize the the offline maps.

Hi Carol,

A few quick tips to solve this issue:

Make sure the declared namespace at the top of your XAML exactly matches the MapView tag.
Try cleaning and rebuilding your solution to make sure Visual Studio isn’t using an out-of-date build.
If you hit design-time errors, close and reopen the XAML file, or restart Visual Studio. Also, check you don’t have any conflicting ArcGISRuntime packages installed.
Confirm your project’s target framework is .NET 8 or higher, as required for the latest SDK.

If you still run into trouble, please provide a minimal sample so I can help diagnose the issue directly.

Good luck with your project!

Also make sure you target `net8.0-windows10.0.19041` or higher with the explicit windows version in the target framework. A new WPF project typically just specifies `net8.0-windows` which is equivalent to Windows 7. We require at least `10.0.19041`.

Btw you don't need to install `ArcGIS_Maps_SDK_DotNet_200_7_0.vsix`. That just gives you a local nuget repo of the packages (for offline scenarios), but they are on nuget.org so they'll just pull from there instead.
