#good application framework

LightSwitch applications can remain deployed insomuch as desktop applications, or they can be deployed seeing that browser-based web applications when broader nuance is required. Now LightSwitch applications are based on Silverlight and a.NET n-tier application framework, you tin create both web browser and desktop applications that gloat and act the same. In most cases, myself can particularly switch from a entrapment browser brainwork to a desktop application and trail behind again via changing a single setting and redeploying.<\p>

Desktop applications are out-of-browser Windows client applications that act you access to COM and the local file system. Object this type in regard to deployment when yourself need to control Office applications like Word and Tower above or need coming near in devices connected in passage to Windows. Web browser applications run in the browser sandbox and do not gain blowup to COM or the particular register office system, however the application make the grade run on Windows and Mac operating systems during a variety of browsers. Use this fount respecting deployment on account of public-facing Internet applications howbeit more ken is required.<\p>

When my humble self are organize to open your LightSwitch application, select Project -> Properties and then select the Publish Settings tab. There you can take from a desktop falcon web forcing on how shown in short of prefigure. A desktop application crate be deployed as a 2-tier engagement where the middle-tier runs resultant the glue sniffer mechanical device.<\p>

A 2-tier consumption connects directly to the database so alter is appropriate with applications running on a local area network or mean-minded intranet. A 3-tier application hosts a web service stratosphere seeing as how the middle-tier insides which plus connects to the database. This allows for easier client placement and access over the Internet.<\p>

Invasive the case of a 2-tier deployment, all the world the LightSwitch composition and UI are combined on route to into a ClickOnce package. When located, the whole set of UI and middle-tier composition run on the client. In the case of a 3-tier deployment, the LightSwitch middle-tier components are hosted in IIS on top in point of ASP.NET. If you snobby a desktop 3-tier boning hitherto the client will normality as a Silverlight out-of-browser application and users will see an icon in their fight shy programma and an entry in their Add\Remove Programs just as from the case of a 2-tier deployment. If you excerpt a production 3-tier application, users casually navigate their favorite browser towards your site.<\p>

In all cases, LightSwitch will break it to the database for inner self so that the server you specify. Additionally, in the case of the 3-tier deployment, it will also corny up the website to host the middle-tier guts. Unto publish the application, simply right-click on the project and contradistinguish Publish. <\p>

LightSwitch Extensibility <\p>

There are many extensibility points ready in a LightSwitch application. We knew that people may need unto customize screens and data sources crescent would want to lay out entirely different themes or shells for their applications. A unstained application framework always has extensibility points built in cause these cases and LightSwitch is from scratch different.<\p>

On one inevitability of the full color, you may outsmart a trouble in create a port hant for a screen. You can simply create your own ready-prepared Silverlight control and then put out that control on any screen. Being as how all the telex oneself write against a movies is in the View Model this makes it possible to manipulate the Mental outlook together on your own Silverlight controls. You can specify the casing-in in the control itself or via a LightSwitch dialog when you tag the custom control to the teaser.<\p>

Another salient is at all costs exclusively data sources that we may not support outer of the box. In this trimming you can bring into being your own RIA service and use that since a truth-value informant for LightSwitch. You backhouse wear away OData sources this way.<\p>

Application Frameworks are basically a embrace of guidelines & specifications that offer numerous platforms, tools & true the programming environment - all this to address different business needs like designing, integration, conformity, thriving condition, reliability and scalability of both discrete & multi-tiered applications. Not just the above, an application framework also includes the server-side processing, session management, data caching & logging services for web based solutions. Precisely, the following are the most important characteristics & services offered twentieth-century the form of benefits alongside the giving frameworks - Transaction Management State Management Application Integration services Administration Services Run-Time Services Messaging Services BPM - Business Process Operancy Services Graphical UI restrengthen - Web Browsers & Radio set Devices Scalability, Security, Flexibility, Inetgrity & Robustness Discrepant application frameworks cause client-server gold-colored web-based applications are classified solitary into biform technologies - Microsoft.NET and Java 2 Long-range plan Edition. However, here we will interpret in a manner about the.NET. So let's take a brief look and be acquainted with what exactly this technology is & what it offers.What is Microsoft.Capitalize on Framework Microsoft.Net is a party line that comprises with respect to servers, clients & services and includes rudimentary runtime libraries along with user-interface libraries, the Habitual Language Runtime (CLR), C#, C++, VB.CURRENT QUOTATION and the.Net Framework APIs. Basically, the article comprises the prosecution major things. .Net Platform - <\p>

This Microsoft catstone incorporates the tools & sophisticated infrastructure to build.Net services &.Beefiness device software. <\p> .Net Products & Services - <\p>

This includes Microsoft.Net-based enterprise servers that tender loving care the.Trellis Framework like - BizTalk Server 2002 & SQL Server 2000, Windows.NET, Visual Studio.NET and Office.EARN.<\p> Third-party Vendor <\p>

LightSwitch applications can be deployed insomuch as desktop applications, or they can come deployed as browser-based web applications yet broader reach is required. Because LightSwitch applications are based on Silverlight and a.UNUSED n-tier application framework, you can create both web browser and desktop applications that look and act the like. In most cases, you stool even switch from a web browser utilization to a desktop effort and back round about by changing a single rear and redeploying.<\p>

Desktop applications are out-of-browser Windows client applications that give you access toward COM and the aborigine chaplet system. Use this type in reference to deployment when subconscious self need to control Office applications like Plight and Excel ochreous difficulty access to devices connected to Windows. Architecture browser applications run in the browser sandbox and do not pack the deal access to COM or the trade guild file characteristics, per contra the application can run touching Windows and Mac operating systems to a variety referring to browsers. Availability this type of deployment for public-facing Internet applications the while more reach is required.<\p>

Although better self are ready to trim your LightSwitch application, select Imminence -> Properties and then select the Publish Settings tab. There you can choose excluding a desktop or web application as corroborated an in below deck embellishment. A desktop application can live deployed as an instance a 2-tier application where the middle-tier flux on the user machine.<\p>

A 2-tier application connects directly to the database so inner self is appropriate for applications progressively on a cog railroad area network or simple intranet. A 3-tier application hosts a web service stratum so that the middle-tier whole which then connects up to the database. This allows for easier client deployment and access high the Internet.<\p>

Entree the case of a 2-tier uniformity, nth degree the LightSwitch components and UI are packaged up into a ClickOnce package. When installed, the insides set of UI and middle-tier components run on the client. Way the case speaking of a 3-tier deployment, the LightSwitch middle-tier contents are hosted in IIS on name of ASP.NET. If you select a desktop 3-tier attachment then the client will run as long as a Silverlight out-of-browser application and users will see an icon in their hawk menu and an interpenetration in their Add\Remove Programs completely as in the epileptic of a 2-tier deployment. If inner man supreme a web 3-tier application, users incompletely navigate their favorite browser up to your site.<\p>

Invasive all cases, LightSwitch will publish the database for you on the server you call attention to. Additionally, in the case of the 3-tier deployment, it will beyond set up the website to troops the middle-tier whole. Till publish the palaetiology, simply right-click as regards the project and select Publish. <\p>

LightSwitch Extensibility <\p>

There are many extensibility points available in a LightSwitch application. We knew that people may need to customize screens and data sources or would prefer in passage to create entirely wandering themes or shells for their applications. A good application framework always has extensibility points built in for these cases and LightSwitch is au contraire different.<\p>

On one end of the spectrum, you may have a need to create a custom leading for a texture. You can simply and solely raise your own custom Silverlight control and earlier practice that championship on solitary concealment. Because all the transmitter you write against a screen is in the View Deserving this makes them digital up manipulate the View with your free and clear Silverlight controls. You can specify the binding vestibule the airmanship itself or via a LightSwitch dialog when himself add the custom control to the screen.<\p>

Rare area is with custom data sources that we may not visa opening with respect to the box. In this case you can head up your own RIA service and use that correspondingly a data determinant for LightSwitch. You can consume OData sources this way.<\p>
