After an async createReplica job on a feature service finishes, the replica is ready to download using a link given on the job status page. One can download the replica all at once. But, like most REST endpoints, one could use the common HTTP range header to download the replica a bit faster: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Range For example, the replica could be downloaded in 10MB chunks, 5 chunks at a time. Then, the chunks would be reassembled programmatically after all chunks were downloaded. This is a fairly common practice for larger HTTP downloads. From my tests, ArcGIS Server does seem to respond properly when called with the RANGE header (replies with 206, gives back only the number of bytes requested). But, I'd like official support if we are to base code on this behavior. Is it officially supported? A few examples of others using the range header: https://stackoverflow.com/questions/3303029/http-range-header https://www.infoworld.com/article/3198668/how-to-work-with-http-range-headers-in-webapi.html

Sounds good. I'm glad the teams are planning to address this. May I also suggest: anything that implements ILoadable should over-explain why they couldn't load. There's a lot of possible reasons for a failure during operations like this, so we will need as much info as possible to solve issues that arise. Thank you!

When loading the meta-data for a map service using LoadAllLayersAndTables we see this error: After digging around in the service's meta data for several hours, we discovered the issue was with the line width of one of the layers. For some odd reason, it had been published with a negative width. Not sure how that is possible, but the main concern for me is this error message. It is terrible at communicating information that would allow the user to figure out the problem. No layer names, no information about symbology. Lots of repetition of metadata and sublayers and "width must be 0 or greater". We don't even know what "width" it is talking about. Sorry to rant, but this method call is so broad (loading all meta data from a map service), it needs to be specific about the layer, field, renderer, or any other part of the JSON it was parsing when it encountered the error. Please add this as soon as possible for this error. And please consider adding at least the layer name to all such errors that are possible while parsing service meta-data. Thank you!

Some of our users are experiencing issues with sync replicas when using them in our Runtime app. Unfortunately, they don't have a lot of information to correct the situation. The Runtime just says "Geodatabase field not found" when our app tries to look at one of the tables. Please improve the error message to saw which field cannot be found. Please mention the table name too. This would help their diagnosis immensely. Exception below: Esri.ArcGISRuntime.ArcGISRuntimeException: Geodatabase field not found.

An FYI to the Runtime dev teams... Getting an odd SQLite error when trying to use sync replicas. This has also been observed in Collector: https://community.esri.com/t5/arcgis-collector-questions/strange-error-with-sqlite/m-p/1096824/highlight/true#M13463 A fix in Runtime is probably needed.

We see similar errors when using Runtime with sync replicas. Seems like Runtime might need a better error message. An FYI.

We are seeing this error in telemetry, saying that our Xamarin.Forms app is crashing out with this error. We can provide detailed logs if needed.

Indeed. We plan to maintain this dependency through our trust in Microsoft's build agents, used from within Azure DevOps. Should be pretty reliable. As for the Runtime docs, I would ask that "Local install" is explained a bit more. I knew what that meant, but I'm not sure all Runtime developers would. Microsoft is un-helpful there too. But, at least the esri docs could refer to Microsoft's docs on the matter. https://docs.microsoft.com/en-us/cpp/windows/deployment-in-visual-cpp?view=msvc-160#local-deployment https://docs.microsoft.com/en-us/dotnet/desktop/wpf/app-development/deploying-a-wpf-application-wpf?view=netframeworkdesktop-4.8 https://docs.microsoft.com/en-us/cpp/windows/walkthrough-deploying-a-visual-cpp-application-to-an-application-local-folder?view=msvc-160

If anyone has been looking for the best way to deploy the C++ Runtime with your esri Runtime WPF app, here's the content we brought into our app package. We copy from these locations: 32-bit: c:\windows\syswow64*140.dll C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x86\* C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\redist\x86\Microsoft.VC140.CRT* 64-bit: c:\windows\system32*140.dll C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x64\* C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\redist\x64\Microsoft.VC140.CRT* 32-bit files go into the ArcGISRuntime100.11\client32 folder. 64-bit files go into the ArcGISRuntime100.11\client64 folder.

We see the following crash error on occasion from 100.10. We haven't shipped our app with 100.11 yet, so we don't have any telemetry from it yet.

Another detail: we went to the data frame properties in ArcMap and changed the coordinate system there. Setting this to British National Grid to match the data that was in the GDB didn't work. Nor did setting the data frame coordinate system to WGS 1984 World Mercator. Both data frame coordinate systems resulted in the same offset.

Using the .NET Runtime, we've noticed that the server-side rendered tiles from a map service do not show up in the correct locations. The Runtime app starts with a public esri WGS84 basemap and asks for tiles in that spatial reference. It appears the tiles sent down are not projected into WGS84. They are offset to the north. This can be seen in the attached screenshot (the black line should be where the red highlight is). Manually re-projecting the feature data to WGS84 at the geodatabase level corrects the offset, as there is no re-projection in this case. Is there a setting in ArcGIS Enterprise/Server that prevents on-the-fly re-projections in the Server-side rendering pipeline?

We've seen some crashes coming from the MapView class in the iOS build of our Xamarin.Forms app. They occur when adding a new ArcGISMapImageLayer to the MapView. I'm posting them here for the information of the Runtime teams to discover a potential issue to fix for future versions. We are using Runtime 100.9. Reach out if you need a more complete crash dump.
