Using the Microsoft.LightSwitch.ExportProvider.dll to utilize the MEF in LightSwitch

iamrommel — Thu, 09 May 2013 14:53:11 +0000

Lightswitch was built using MEF!

And one way to compose export and other MEF stuff is to use the assembly Microsoft.LightSwitch.ExportProvider.dll (which is normally found in LS installation folder C:\Program Files (x86)\Microsoft SDKs\LightSwitch\v3.0\\Client\Microsoft.LightSwitch.ExportProvider.dll, take note this should be version 3 of lightswitch).

And normally to utilize the composition you can use the “VsExportProviderService” class as such shown image below (note: i have already class that attributed as “Export”, just like normal MEF way)

Composing the class using the Lightswitch VsExportService

But when you are going to use this VsExportService outside the context of Lightswitch of course it will NOT compose for you, but you can use the VsCompositionContainer to fill up the container with export values.

Adding property data item on screen designer will give you the option to choose the display control in Lightswitch

I found out that some screen just needs a property but is not ‘string’ but other complex type. And in addition to that can be displayed as any compatible control on LightSwitch screen. This useful when you want to show and entity not as grid or list but let say as independent autocomplete box. See the image below

Adding LightSwitch property on the screen aside from string will open up the option for selection of control

Specflow Visual Studio 2010 integration

iamrommel — Mon, 30 May 2011 01:13:49 +0000

Introduction

This page will discuss some features of Specflow 1.6.1 that is integrated with Microsoft Visual Studio 2010. Features like

Visual Studio Intellisense (auto-completion)
Auto formatting
Goto Definition
Debugging (to do)
Resharper, AgUnit and Silverlight (to do)

because providing cool editor for Visual Studio is one of the goal of Specflow developers.

Visual Studio Intellisense (auto-completion)

IntelliSense is one of the feature that makes Specflow easy to use when integrated with Visual Studio. It provides a lists available steps definition and possible sample. It’s an auto complete because as you type it suggests based on the typed characters. It does not only displays the steps in the current file but for all "*.feature" files, filtered by what type of step (either Given, When or Then)

Figure 1: Specflow Integrated with Visual Studio and IntelliSense (click the image to see the full size)

As you can see from the Figure 1, the IntelliSense feature pop up (shown with Red Rectangle) in the Given step and it suggests existing (the first two from the IntelliSense pop up) steps from "GetProducts.feature" and "AddProducts.feature". The step has already C# code definition that is why it also specified in the pop-up with "–>" characters

Auto formatting

VS2010 "Edit–>Outlining" menu item works well with Specflow feature file. Even most of the items on "Edit" menu. The "table" in Specflow is also formatted in a nice way with as you type for the column names and values, it automatically expands (shown in figure 3).

Goto Definition

Another sweet feature is the right-click "Goto Definition" of steps in *.feature file and it will automatically brings you to the C# code steps definition you have (Figure 4). And if the steps definition does not exists it show a message box and ask to copy to clipboard the template steps definition (Figure 5). One thing I notice if the the steps definition is in the partial class and sub-group (like the form1.designer.cs is subgroup of form.aspx) "Goto Definition" does not work
