I have a requirement to have separate basemap styling for day and night mode and are using a local vector tile package for basemaps as part of an MMPK. In theory this should be possible with vector tiles, but I can't find any samples or documentation on how this can be acheived in the runtime SDK. The ArcGISVectorTiledLayer class constructor seems to have the option of specifying an ItemResourceCache, which appears to offer a way to override styling, but it can't find much in the way of documentation on what the ItemResourceCache format should be or how to create it. https://developers.arcgis.com/net/api-reference/api/netwin/Esri.ArcGISRuntime/Esri.ArcGISRuntime.Mapping.ArcGISVectorTiledLayer.html Does anyone know what the format/structure of ItemResourceCache should be or how to create it? If anyone else has tackled this, I'd be grateful for any insight. John

I'd also like to be able to do the same by switching the styling of a vector tile basemap that's part of an MMPK. Did you ever find a way to do this?

Thanks a useful link, thanks. Though I was hoping for a way to generate the required renderer json from ArcGIS Pro or something similar, but perhaps that's not possible. It seems like with the mobile SDKs you are largely left to your own devices with regards to symbology etc.

Hi I've been experimenting with how to apply renderers to various locally stored data that are loaded as feature layers. I would like to retreive the layer symbology from a configuration file or similar and don't want to hard-code like in many of the samples. It appears one way to do this would be to use the Renderer.fromJson(string) static method to generate the renderer from stored json and then apply it to the layer. There is no documentation on what format is required as input for Renderer.fromJson(string), but I have done some experiementation and found the following: 1) The json format for the renderer returned from a feature service published from the same data in Pro seems to work. This is similar to what is used in the JS API. 2) The json format for the renderer that is used in the mmap file that is part of an mmpk created from the same data also seems to work. 3) The json format used in a layer file (.lyrx) created from the same data in Pro does not work. So my questions are: A) Is there a better way to store and apply symbology to layers in the .net API? B) If not, then is there a better way to generate the required renderer json for each layer, preferably from Pro? I feel certain someone else will have attempted similar, so any thoughts/experience appreciated. Thanks John

Hi I've tried to implement a download of a mobile geodatabase from an ArcGIS Online feature service followed by a sync based on the sample at https://developers.arcgis.com/net/uwp/sample-code/edit-and-sync-features/. I have set the feature service as public (for testing) and the initial download using GenerateGeodatabase works ok, without any authentication. However, when I then try to perform a sync (download only) I'm getting prompted for ArcGIS credentials. If I enter credentials it just continues to prompt, then if I cancel I get an error as follows: Esri.ArcGISRuntime.ArcGISServerException: 'Service error code 401: Unable to synchronize replica. Details: No permission to edit replica data : 96f78289-48df-4a19-9b4c-02352c905a44.' So I have some questions: 1) Why does sync require credentials when download doesn't - even though the service is public? 2) The licensing documentation suggests both download and sync are available with a Lite license, which uses an API key. If the feature service was secured, what is the correct way to provide credentials if the app does not use a named user? Should we use application authentication? Any thoughts appreciated. Thanks John

Hi Nathan Did you ever work out how to do this? I have a similar requirement to apply a different style to a a vector tile package. It seems like it's possible, but there's not much info on what the ItemResourceCache should look like!

Yep - this is really poorly implemented. I have a template created in Pro with a scalebar that has units set to meters. This is published via a print service. The default in the print widget advanced section appears to be "miles" and if this is selected the scalebar on the resulting print is in km! The widget definitely needs the option to set the default units (and other defaults) so that we don't have to tell every user to manually set them each time they print. This isn't a seldom used widget either, it is used by many, many organisations I'm sure and any organisation that doesn't use miles will be affected!

Mixed case objects should absolutely be supported (as they are in other DBs) if they are supported by the database. This issue is likely to affect and put off potential customers wishing to transition from Open Source (e.g. QGIS) to Esri.

Hi @parksh - no we didn't. However, we are just starting to look at this again in more detail in the coming months, so will post any findings here.

Hi We are looking to monitor ArcGIS Server (v10.7.1) on Azure using some of the built in Azure Monitor capabilities (e.g. Log Analytics, Alerts, Application Insights). I've been looking at ingesting the ArcGIS Server logs and trying to follow what's in the following Esri presentation, but our ArcGIS Server was not installed with cloud builder and has logs that are in xml format, not csv format as describe in the presentation. ArcGIS Enterprise: Cloud Operations using Microsoft Azure So questions are: 1) Is it possible to ingest traditional xml-based server logs using Log Analytics? 2) Is it possible to change the ArcGIS Server logging to csv - how is cloud builder different? 3) Does anyone have any other advice/recommendations regarding monitoring ArcGIS Server in Azure? Any assistance much appreciated, as there seems to be a disconnect between the Microsoft Azure documentation and what is possible with ArcGIS Server.

Sorry for the delayed response. We did resolve this issue through discussion with Microsoft, who's suggestion was to use the cmdkey utility exactly as you have described. Importantly, this needs to be run as the service account user by opening a command prompt as that user. We were then able to use the UNC path in the ArcGIS Server configuration.

Hi We are trying to deploy a high availability architecture for ArcGIS Server (not Portal) v10.7.1 on Azure and need to configure ArcGIS Server instances to use an Azure file share for configuration and directories, but are having some issues with this. Note that we are NOT using (and cannot use) Cloud Builder due to restrictions/standards in place on the customer's Azure environment. Instead the customers Dev Ops team has scripted the build of VMs and file shares etc. We are then manually installing and configuring ArcGIS Server on the VMs. So far we have tried creating a mapped drive under the user account that ArcGIS Server is running under on the VM and using the UNC path in the site configuration options when creating a new site. This works initially, but then fails later and the site is unusable. So - my question is - what is the correct way to configure ArcGIS Server to use the Azure file share for configuration and directories? I have found the following article relating to Amazon S3 setup, which suggests using createNewSite under the ArcGIS Server administration directory and then supplying some json configuration for the storage locations. I suspect we may need to do something similar for our Azure file share, but we can find no similar documentation for Azure: Configure a highly available ArcGIS Server with a shared configuration store on Amazon storage services—ArcGIS Enterpris… If anyone can point me in the direction of the documentation for Azure or give any guidance on this it would be greatly appreciated. Or perhaps if you have configured your site in this way (with or without cloud builder), you could supply the json that was used to configure it? Regards John

Hi - I can currently access any license authorisations prior to 10.6x under my developer subscription. Any chance this can be fixed?

‎06-12-2019

FYI - There is also now a Dashboard theme within Web App Builder which has some similar functionality to Operations Dashboard, but with Web App Builder you can create custom widgets.

As discussed above, we are using http requests via Python. Therefore whether any changes are required for the February TLS 1.2 update depends on the version of ArcGIS and therefore Python that is installed. In this case, our customer has ArcGIS 10.4.x, which installs Python 2.7.10, which uses TLS 1.2 by default, so should not require any changes. Whether the python version uses TLS 1.2 can be determined by following the steps mentioned here - How to check if your Python app supports TLS 1.2 | Calazan.com. However, if you're using ArcGIS Desktop to connect to ArcGIS Online or other connection methods, then you may need to take some action. There is more information available here - Esri Support Important Updates for the ArcGIS Platform and Transport Layer Security (TLS) Protocol Support.
