This article describes how to simulate a long operation in Dynamics 365 (CRM) using a simple custom plugin that introduces a delay using the Thread.Sleep function.
Background: recently we have been investigating an issue regarding some timeouts happening in a third party application which connects to our Dynamics 365 service. At the moment, it is difficult to tell if those timeouts are due to some slow connections to Dynamics or other reasons. In order to help us with this investigation, we are going to set the Timeout property of the OrganizationServiceProxy in the client application, which by default is 2 minutes.
Before applying this change, we also want to test it and simulate some long queries that would last longer than the client timeout limit set for the OrganizationServiceProxy. Here is where we have created this simple plugin “DelayOperation” that is going to introduce a delay for a certain number of seconds.
For testing purpose, I have prepared a simple test that creates a Task record. See below the corresponding code:
Then we have registered our “DelayOperation” plugin in the create message of the Task entity, see below this plugin registration step:
Notice we pass the number of milliseconds to be used by the Thread.Sleep function as an unsafe plugin parameter. In our example, the client would wait for 10 seconds and the plugin would delay the operation for 12 seconds, causing the client to timeout.
Finally, our “DelayOperation” plugin code is:
You can download all this code from the following Github project:
I hope you find it useful!
The new CRM SDK 2015 doesn’t give support yet for our known CRM Developer Toolkit, which has been part of the CRM SDK until CRM 2013. Basically, the CRM SDK 2015 assemblies have been compiled with .NET Framework 4.5.2, but CRM Developer Toolkit was compiled using NET Framework 4.5. See the next Microsoft article for more details.
For instance, let’s check the new assembly Microsoft.xrm.sdk.dll part of the CRM SDK 2015:
The good news are… we still can make compatible the Developer Toolkit with the latest CRM SDK 2015 editing the .NET Framework in the corresponding projects of our Visual Studio solution. Let’s say we have the next CRM solution:
For plugins and workflows, we should update the references to the new assemblies and also the .NET Framework in the project properties:
After updating those references, we could still find the following error:
“The type or namespace name ‘Xrm’ does not exist in the namespace ‘Microsoft’ (are you missing an assembly reference?)”
This error is indicating you haven’t got installed the expected .NET Framework 4.5.2. Do right click on the same project and select Properties to check the version actually used:
If you are only getting old versions of the Target Framework, select “Install other frameworks…” that will take you to the next site:
There you must download .NET Framework 4.5.2 Developer Pack.
After it has been installed, you get a new option in that previous list:
Finally, we need to do something similar with the CRM Package Project. But in this case, we will have to edit the project file and update the entry “TargetFrameworkVersion” to “4.5.2”. Start unloading the project:
Update the mentioned entry “TargetFrameworkVersion“:
Finally, reload the project again and everything should work now!
About this last part, I would like to say thanks to my CRM MVP colleague Scott Durow (@), who helped me to find that entry.
If you don’t update the package project, it may still compiled, but the actual deployment will fail and you should see the next warning in the Visual Studio output:
warning MSB3274: The primary reference “[Your Assembly Name].dll” could not be resolved because it was built against the “.NETFramework,Version=v4.5.2” framework. This is a higher version than the currently targeted framework “.NETFramework,Version=v4.5”
warning MSB3275: The primary reference “[Your Assembly Name].dll” could not be resolved because it has an indirect dependency on the assembly “Microsoft.Xrm.Sdk, Version=188.8.131.52, Culture=neutral, PublicKeyToken=31bf3856ad364e35” which was built against the “.NETFramework,Version=v4.5.2” framework. This is a higher version than the currently targeted framework “.NETFramework,Version=v4.5”
CRM SDK is now also available from the Visual Studio extension NuGet. This extension is a provider of third party packages where anyone can participate and publish their own ones. This makes very easy to add third party assembly references.
- Install NuGet in Visual Studio from “Tools => Extensions and Updates”
- Once NuGet is installed, create a Visual Studio Project (a library for example) and make right click on the Visual Studio project where the CRM SDK assemblies will be used. Select “Manage NuGet Packages…”
- Choose the Online option on the left menu and search for “crmsdk“. A list with all the CRM SDK assemblies published by Microsoft will be presented. Choose the corresponding assembly based on its version.
In this case, I have installed the CRM 2013 assemblies:
Notice the new package and reference configuration linked to the project:
- “packages.config” file in the project where the NuGet packages have been installed
- New folder with the assemblies in the root solution folder. You can find the assembly file within the package folder. In this case, the new CRM 2013 SDK package contains two assemblies, see below:
- New library reference have been added automatically to the chosen project:
Microsoft Developer Network has just launched. Microsoft wants to enhance the experience to add better support for the growing number of developers that are embracing Microsoft’s platform and technologies for the first time.
There were a few goals Microsoft targeted with the Microsoft Developer Network experience:
- Simple: The new Microsoft Developer Network site is designed to help developers easily find information and get started with Microsoft more effortlessly. They heard from the community that finding the right information, often spread between different locations, could be challenging. The Microsoft Developer Network addresses that feedback by providing a single point of entry for all developers.
- Relevant: They want to meet developers where they are and talk with them on their terms. With the Microsoft Developer Network, an iOS developer, for example, can quickly understand the opportunity available from our platform and then easily navigate to the educational or technical content he needs to get started.
- Community Driven: Microsoft has an incredible developer ecosystem, and they wanted to provide even more opportunity for the community to engage with them and with each other. They designed the Microsoft Developer Network with that in mind, creating a “Perspectives” section with community blogs, an integrated social feed, and a “Connect” area that allows developers to tell their stories, get advice and connect with them directly.
The site launch happened last week for English-based geographies, but this is just the beginning of a phased worldwide launch. Expect to see the global launch roll out over the next few months!
