I was working on a project where I needed a pool of PowerShell workers that were distributed across several nodes and should be served by a central dispatcher. So why not give AMQP with RabbitMQ a try? The setup was very easy thanks to the documentation. And besides plenty of .NET library wrappers around “Rabbit.MQ.Client.dll” there were even two PowerShell […]
A quick follow up on my last post regarding TFS and PowerShell. I found it quite amazing that is so little documented and relatively difficult to download a file from TFS to your local machine. I would have expected that the supplied Cmdlets in the TFS Power Tools snapin will just handle that for you, as I find the requirement […]
Today I was playing with TFS Power Tools to check in some PowerShell scripts where I ran into a strange error. Obviously I wanted to use the PowerShell Cmdlets for that you can select via the ‘Custom’ option in the ‘Power Tools’ installer … For a quick intro on TFS via PowerShell you can have a look at PowerShell and […]
Have you ever tried to use ODATA Actions from PowerShell and realized that the Service Reference in your class library does not expose them? You can actually do it via the model’s ‘Execute()’ method. Here is a quick description on how to do it without writing too much URL style code. Let’s presume we have a model referenced in a […]
When working with ODATA sources from PowerShell via a service reference (instead of using explicit REST call via Invoke-RestMethod) the .NET DataServiceClient will use Atom/XML under the hood. This works perfectly well except it consumes much more bandwidth because of the XML data format. As the whole ODATA interface is encapsulated via your service reference it really does not make […]
I just came across another nuisance in .NET WebAPI that I want to share with you quickly. In one of our LightSwitch projects we use WebAPI ODATA controller to help out when LightSwitch internal capabilities come to their end. As we are using a PowerShell once in a while as you might already have guessed from our web site we […]
In this post I quickly describe how you can use the select2 plugin with LightSwitch HTML client and present data from ODATA sources via jaydata. LightSwitch has builtin capabilities for selecting related entities via the ‘Modal Data Picker’ control. You can also have drop down or choice lists with static data, however they lack the convenient search and filter mechanisms […]
It might sound old school and the JIRA SOAP service is announced to be removed with version 7 (https://developer.atlassian.com/display/JIRADEV/Preparing+for+JIRA+6.0#PreparingforJIRA6.0-SOAPandXML-RPCdeprecatedinJIRA6.0) but the JIRA SOAP protocol is really easy to use from PowerShell as of the nifty ‘New-WebServiceProxy’ Cmdlet that abstract the SOAP protocol behind typed .Net objects. So whenever you want to do a quick upload of a screenshot or get […]
When you try to add an assembly that you downloaded from a network share or the internet to your PowerShell session via ‘Add-Type -Path C:\folder\your-assembly-name.dll’ you might a receive an error like this: The result itself could give you a hint and querying the inter you will probably others experiencing the same error as described in Visual Studio Project Sample […]
[UPDATE] 2014-11-28 Jerther sent me a comment (see below) on how he solved this issue! So how did he do it? The short answer is, that you have to include special registration code inside the ‘Application_Start()’ and other places where the order on how you code it plays a crucial role. Check out his post ASP.Net: Web API 2 + […]
When trying to add the current “Microsoft.AspNet.WebApi.OData” to a LightSwitch project I got the following error message: We are not using Silverlight in our application, only the HTML client – except when doing user and role administration … As a matter of fact we only need the package on the server layer anyway. So the solution to this is to […]
This will be a quick post about WebAPI and ODATA controllers, and a strange “bug” or behaviour I found. I was not aware of this, so maybe it is also of some interest for you. When you create an ODATA service via WebAPI and want to connect two or more entity sets via a relation the standard example will tell […]
Graylog2 comes with a very limited alerting feature where you can basically only create alerts based on a single field. However, and thus far I can follow the motivation of […]
Graylog2 is a powerful and scalable open source log management and data analytics system on top of elasticsearch. Since our logging module is based on log4net, the integration of Graylog2 […]
LightSwitch can consume ODATA data source that you can use to gain more flexibility than using the internal data sources that also generate ODATA REST endpoints. Microsoft Web API provides an easy way on how to generate these endpoints. In this post I quickly describe the steps you need to take to actually create an endpoint that is actually usable […]
Finally I made it and found the time to upload the biz.dfch.PS.vCAC.Utilties PowerShell module! It is available for download at Github and NuGet (see below for links) and placed under the Apache 2.0 license. How to install: Copy the module along with the XML configuration file into a directory with the same name as the module under a path that […]
