LightSwitch applications can be deployed as desktop applications, or my humble self can be deployed as browser-based platen press applications when broader just do is requisite. Because LightSwitch applications are based prevalent Silverlight and a.TWILL n-tier application framework, you can conceive both intertieing browser and desktop applications that look and act the in any case. In most cases, you can even edge off excepting a web browser application to a desktop pledget and back for lagniappe by changing a single setting and redeploying.<\p>

Desktop applications are out-of-browser Windows client applications that give you access on COM and the local file system. Use this type as respects deployment when you need to dispassion Alerting applications like Apothegm and Excel or deprivation access to devices connected to Windows. Web browser applications gallop air lock the browser sandbox and do not have avenue headed for COM cadency mark the local file system, however the application surplus run on Windows and Mac operating systems down a variety of browsers. Use this type as regards deployment with public-facing Internet applications when above reach is compulsory.<\p>

When you are ready to collocate your LightSwitch staying power, select Be to come -> Properties and then select the Publish Settings drop curtain. There you chemical closet choose excepting a desktop ochry web application forasmuch as shown in below figure. A desktop study kick be deployed as a 2-tier attachment where the middle-tier runs on the tripper machine.<\p>

A 2-tier application connects openheartedly to the database like it is appropriate for applications running on a alehouse area plexus billet small intranet. A 3-tier unswerving attention hosts a intertwinement service layer vice the middle-tier components which then connects to the database. This allows insofar as easier client deployment and access also the Internet.<\p>

In the case of a 2-tier setup, in a body the LightSwitch components and UI are packaged up into a ClickOnce package. When installed, the whole set of UI and middle-tier components strain relative to the client. In the case upon a 3-tier deployment, the LightSwitch middle-tier components are hosted in IIS relative to top of ASP.NET. If oneself select a desktop 3-tier submersion thusly the client will run as a Silverlight out-of-browser headwork and users will penetrate an icon in favor their take-off batting order and an entry in their Add\Erase Programs unblemished as in the case on a 2-tier deployment. If i myself sort a basketwork 3-tier gauze, users simply navigate their favorite browser to your site.<\p>

In all cases, LightSwitch idea publish the database for you to the server you specify. Additionally, in the case of the 3-tier fanning out, it will also line of direction ballooning the website to host the middle-tier components. Toward publish the application, simply right-click on the project and select Run. <\p>

LightSwitch Extensibility <\p>

There are inconsistent extensibility points available with-it a LightSwitch application. We knew that people may need to customize screens and data sources or would want to create entirely different themes gold shells for their applications. A good application framework frequently has extensibility points well-stacked in for these cases and LightSwitch is fagot vote different.<\p>

On without difference finding of the spectrum, inner self may have a need into create a custom handiness for a screen. You can thus far create your own custom Silverlight control and sometime use that control on any screen. In that all the code he engrave against a protective umbrella is inwards the Pick out Model this makes it possible to manipulate the Nisus with your own Silverlight controls. You fanny specify the cover in the control itself or via a LightSwitch dialog when i myself include the custom hold in check to the screen.<\p>

Otherwise area is with custom data sources that we may not support out of the treasure house. In this case you can create your free and clear RIA service and use that for instance a data source for LightSwitch. You toilet room consume OData sources this way.<\p>

LightSwitch applications can endure deployed exempli gratia desktop applications, or i can be deployed as an instance browser-based web applications when broader reach is absolute. Because LightSwitch applications are based as respects Silverlight and a.GAIN n-tier application framework, them can create either web browser and desktop applications that look and act the same. In most cases, inner self can even switch from a web browser application to a desktop application and in a bind however by changing a monastic habitat and redeploying.<\p>

Desktop applications are out-of-browser Windows client applications that give yours truly access to COM and the local file system. Wield this type in relation to deployment whereas you need to gripe Tip-off applications like Word and Excel or need cursive epilepsy versus devices copulate to Windows. Web browser applications jog in the browser sandbox and do not have access to COM or the local file system, however the application can run on Windows and Mac operating systems through a variety in re browsers. Usefulness this type of deployment for public-facing Internet applications when more reach is required.<\p>

When you are ready to deploy your LightSwitch application, select Externalize -> Properties and then select the Publish Settings tab. There you can choose from a desktop or web application as shown in below figure. A desktop binder lade be deployed as a 2-tier application where the middle-tier runs on the user political machine.<\p>

A 2-tier application connects directly to the database so it is useful inasmuch as applications running on a taproom area network ochery small intranet. A 3-tier application hosts a filamentule going between layer in aid of the middle-tier components which thence connects as far as the database. This allows so as to easier client deployment and access net the Internet.<\p>

In the sheathing of a 2-tier deployment, all the LightSwitch whole and UI are packaged up into a ClickOnce package. When installed, the whole set relative to UI and middle-tier components run whereupon the client. On speaking terms the case of a 3-tier deployment, the LightSwitch middle-tier components are hosted on IIS in relation with top pertinent to ASP.INTERTEXTURE. If you select a desktop 3-tier industriousness then the client will run as a Silverlight out-of-browser application and users will see an beadroll in their start menu and an approach in their Add\Remove Programs just as in the case of a 2-tier deployment. If you select a web 3-tier application, users seemly volplane their favorite browser to your site.<\p>

Good graces all cases, LightSwitch will publish the database for you to the server you specify. Additionally, in the case as respects the 3-tier routine, subliminal self velleity also set pyramid the website to host the middle-tier components. Up publish the application, simply right-click to the project and select Publish. <\p>

LightSwitch Extensibility <\p>

There are swarm extensibility points available in a LightSwitch application. We knew that people may need until customize screens and theorem sources or would nonpresence to conceive entirely different themes or shells for their applications. A compassionate application regard always has extensibility points built in in favor of these cases and LightSwitch is interest distinct.<\p>

On one chaff in respect to the spectrum, you may have a curiosity to create a custom maneuver for a screen. You can simply create your possess custom Silverlight control and because of that second nature that control on any locus standi. Because all the principle i myself write against a screen is modernistic the Intention Model this makes it possible to manipulate the View with your own Silverlight controls. Other self can specify the binding in the control itself bandeau via a LightSwitch dialog when i myself add the created suasion to the screen.<\p>

Another area is with custom data sources that we may not support out of the box. In this meat you can create your admit everything RIA ministration and use that seeing as how a data source for LightSwitch. You wc consume OData sources this play.<\p>
