As I know, we can integrate Kura and Azure IoT Hub.
I followed a tutorial from Microsoft to simulate a device and send data to Azure IoT HUb. Everything is ok.
But when I try to integrate it on Kura.
I followed the tip from Kura to insert external jar ( from Microsoft).
Everything look ok. I exported successful my Bundle.
But when my bundle start, It's not satisfy some conditions with lack class.
Here is the error message:
Instances:
No instances were created because: Can not activate instance of component org.kura.microsoft.simulatedevicesecond.Simulatedevicesecond. The activation throws: java.lang.NoClassDefFoundError: javax/crypto/spec/SecretKeySpec
But the class "javax/crypto/spec/SecretKeySpec" is belong to jce.jar ( existed in java JDK).
Please help me to fix this issue.
Thank a lot.
Your bundle needs to import the package javax.crypto.spec.
I found a solution for my question.
I used wrong version of Kura and Kura Workspace.
I used Kura Workspace 2.2 with Kura version 1.4.
It maked this error. Change it to Kura version 2.x.
Everything is ok

I have a working project with Twilio + Ionic, but I'm wondering if you can help me with adding Azure Communication Services(video call) into my project. I tried to follow the example from the official website, but I think it's not just installing npm library and adding it as usual in my project.
If you want to see a working sample, you can use this: https://github.com/Azure-Samples/communication-services-web-calling-hero
If you're still stuck, please respond here and I'll try to help you directly.

In Orchard 1.x, my setup was the following:
Cloned Orchard 1.x and kept it clean (unedited) and updated on my local repo.
Publish that clone of Orchard 1.x to another local repo that I would keep clean and update from the clone above as necessary.
Create multiple clones for different landlord/tenant sites of the Publish of Orchard 1.x, and set each up remotely in separate Bitbucket repositories. These would have staging/production branches.
The above is just a simplistic version of what I actually did.
With Orchard.Core, since it's currently in Beta 2 (or 3, I think), documentation is still being created. In some instances of documentation, I get the impression I can do a similar thing as the directions are to download the source and reference the appropriate NuGet packages. But I don't see much of anything specific about publish/deploy (except some information from blog posts from about a year ago - which is likely stale).
On the other hand, I see some blog posts mentioning that all you really need to do is reference the NuGet packages to run a site locally, but there is no further insight into the publish/deploy scenario. I can infer that maybe just publishing that might be sufficient, but I am not sure.
As it's still in beta, I have no intention of pushing Orchard.Core out on a live site. I just want to start preparing for when 2.0 arrives. I can test out locally whether or not what I did with Orchard 1.x will work with Orchard.Core, but I want to make sure I do it correctly. Just concerned I might be missing something.
Can anyone confirm the publish/deploy steps for Orchard.Core currently? Any insight is appreciated.
Yes, you can publish the application.
Then, if you are on Windows and want to host it on IIS, you will need install the .NET Core Framework and the ANCM (ASP.NET Core hosting module).
In IIS, create a site pointing to the publish folder, with an application pool with 'No Managed Code' for '.NET CLR version' and 'Integrated' for 'Managed Pipeline Mode'.
I've been browsing the web for a couple hours now looking for an answer to my problem. I am trying to deploy a Web API on Azure Web App Service using VS2017. Everything builds and works fine when running locally but once deployed on Azure (through VS2017) I get this error:
D:\home\site\wwwroot\bin\roslyn\csc.exe
My project is an ASP.NET Web Application (Using Azure Web API template) .NET Framework 4.6.1. I use Microsoft.CodeDom.Providers.DotNetCompilerPlatform Version=1.0.6.0
I also made sure that csc.exe is located in:
Visual Studio 2017\Projects\DeviceManagementAPI\DeviceManagementAPI\bin\roslyn
Just had the same problem and it seems it's a known issue with Microsoft.CodeDom.Providers.DotNetCompilerPlatform 1.0.6 and 1.0.7.
Downgrading to 1.0.5 solves the problem.
Upgrading Microsoft.CodeDom.Providers.DotNetCompilerPlatform to 1.08 worked for me
After a while I simply uploaded manually the roslyn file directly into the server through Kudu. It seems to solve the problem but I still don't know why it won't upload automatically.
Same issue might be caused by missing or incorrect relative packages path. If you're changing solution folder structure make sure all imports have proper path's to avoid missing Roslyn files.
Generally suggest to replace auto-generated ../../../packages/... rabit hole with parameter which will point to correct Nuget folder.
<Import Project="$(NugetPackagesPath)\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.8\build\net45\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props" Condition="Exists('$(NugetPackagesPath)\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.8\build\net45\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" />
EngagementReachAgent.Initialize(); does not exist in the current context
How can I solve this error? I can't deliver push notifications and I can't find anywhere a fix for this error. I tried everything that is explained here: https://azure.microsoft.com/en-us/documentation/articles/mobile-engagement-unity-android-get-started/
You did not follow the instruction well. You need to download and import the Azure Plugin package into Unity. You can get that here. When this is done, the EngagementReachAgent class and the Initialize() function will be present in your Unity project. They are not there now, so you can't use them.
I'm trying to upload a blob to azure using a shared access signature. I have the token and added the nuget package WindowsAzure.Storage to my project. I've tried both version 7.0.0 and 7.0.1-preview.
For some reason I'm unable to resolve the reference when creating an instance of CloudBlobContainer. Also I've tried to just type the using statement but no luck. All azure documentation points to a version 4.4.0-preview, is this the one I should be using?
azure doc ref https://azure.microsoft.com/da-dk/documentation/articles/storage-xamarin-blob-storage/
Best regards
I would just guess that the docs are outdated with the 4.4.0-preview link instead of a link to the NuGet package:
https://www.nuget.org/packages/WindowsAzure.Storage/
CloudBlobContainer seems to be within the Microsoft.WindowsAzure.Storage.Blob namespace.
I would check to ensure that you actually installed the NuGet package as it may have failed silently with other projects.

Changing the PCL profile worked for me. Bizarre.
After installing the NuGet package, you actually need to change the profile on your Xamarin project. You can do this by going to the shared project -> Options -> General – > C#
Change the Current Profile to PCL 4.5 – Profile111 (I have no idea
of what this does.)
You need to retarget your NuGet packages for this new profile now.
Right click on Packages within the shared project, and you’ll have 5
options here.
Retarget will be available. Click that. (Not shown here, as I’ve
already retargeted)
Rebuild your project
How I figured this out
I stumbled across this Xamarin forum post, where someone had the exact same issue. One user pointed us towards a bug report, where PCL references were not added automatically via NuGet package installation. They recommended retargeting, and it worked! Now I can include the using Microsoft.WindowsAzure.Storage.Blob; namespace.
I have a blog post with more info on this.
