Use of having multiple Services for single silverlight application

Posted By:      Posted Date: September 09, 2010    Points: 0   Category :WCF
Hi My project have 4 modules, I have decided to use single service with multiple interface (1 interface for 1 module, i.e totally 4 interfaces) and multiple partial class ( 4 partial class). Partial classes use this interface. But I have another thought of using multiple service ( 4 services, i.e for each module one service class (.svc)). Please let me know, which approach is right?

Multiple domains in single asp.net mvc application




I want to use my asp.net mvc application with multiple domains (maybe of hundreds),

so I have created custom Route class that matches requests including domain.

Each domain could has different routes, so the number of routes in RouteTable can be huge

(eg 500 domains, each 20 routes = 10000 routes in RouteTable).

I am considering how it will be efficient?


I have an idea to replace RouteTable.Routes (of type RouteCollection)

with custom one (of type Dictionary<string, RouteCollection>).

But how I can override default route matching mechanism with my custom mechanism which will be two step:

1) retrieve RouteCollection from dictionary based on domain name

2) retrieve specyfic Route object (standard route matching mechanism)

How can I do this?


Maybe someone has better idea for solving this problem?


Thanks in advance


How to use single windows service to host multiple WCF Services instances (Each instance of WCF is i

How to use single windows service to host multiple WCF Services. I have a mutiple instance of same WCF service in different folder, each instance has unique service name and port. WCFService has reference to Reg-Free COM Reference, i have Native.WCFService.manifest in each folder. Ex: WCFService1 is in "C:\WCFService01\WCFService.dll, Native.OCWCFService.manifest, OCWCFService.dll.config WCFService2 is in "C:\WCFService02\WCFService.dll, Native.OCWCFService.manifest, OCWCFService.dll.config Now i need host above services from single Windows Service. I am trying to create AppDomain for each above WCFService Instance from Windows Service and then host. Its working if i register COM dll in the server using regsvr32, but when i un register COM dll, i am getting unable to load COM component .... This looks like AppDomain is not loading COM DLL and Manifest files. Its looks strange but we need it in this way because we have production and test environment in the same server. Everything works fine if create a seperate Windows Service for each WCFService Instance, but my manager wants single Windows Service :). Any help whould be really appreciated.  ravi kumar reddy

Multiple Services Using single SQL Process


I'm looking to deploy the following services;
Sharepoint Foundation 2010
Business Contact Manager 2010
Windows Update Services
Forefront Client Security
Autodesk Data Management Services 2011.

I would like SQL Server installed on one host system.

Is it possible/good practice  to setup each of the above's databases to a single SQL process. Or does each need its own process. Or which services will work with one another?. The concern is memory usage.

Thank you.

single sign on IIS 7 multiple application pool


We migrated our web server to window server 2008, IIS 7.

We have single sign on application - that we login through one application called "users" and then no need to login to other applications, they all use the same machine key and cookie.

it works fine when all then applications under the same application pool.

but we have one application that is asp.net 2005.  (the rest are asp.net 2003)

 the user application is in asp.net 2003 and that  other application is in asp.net 2005.

so each application is in a different application pool. -

one pool to asp.net 1.1 and other pool to asp.net 2.

when I run the asp.net 2005 application

I get the login page and after I  login  I get the following errer:

HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested Url: /users/Unauthorised.aspx


Important: If I switch the "user" application (the login) to work under the same pool as my asp.net 2005 application, then it works fine with the asp.net 2005 application,but I get the above error for the asp.net 2003 applications
