New Post: Unable to cast HttpApplication to type WebClientApplication

Hi,

I am unaware of why this error is appearing in your application, but maybe you could find the suggestions in the following threads useful:

Also, as described by Michael Puleio in the following blog post, please make sure that your Global.asax file inherits from Microsoft.Practices.CompositeWeb.WebClientApplication:

Hi,

I am getting a server error when I tried to load a page that was deployed in server, which does not appear when I browse the page local using visual studio. I am using VS 2008 and WCSF. Project and other Dlls are all there. What else is missing? Any ideas to resolve this?

For future fellow googlers the answer is to use the XML entity for quot

Sagarag05 — Thu, 07 Mar 2013 10:38:05 GMT

Hi blainew/brumfb,

Reading at your reply on using project silk as Web Client Developer Guidance (Software Factory) is no longer supported, does Silk support a hybrid model of simultaneously using asp.net legacy pages (aspx) and new views/controllers etc that Silk would bring ?

We know that aspx and MVC could co-exists but not sure if using Silk with legacy aspx pages would work?

I'm currently using Web Client Software Factory and was thinking for a better alternative to it since it's sort of deprecated.

Any recommendations for this?

Hi,

Based on the aforementioned links, it seems that Microsoft no longer maintains this projects and no future releases are planned for them. Future developments of these assets are now undertaken by the community.

Hence, I believe you could try migrating the source code of the WebClientFactory Guidance Package project from VS2010 to VS2012. In which case you may find the following MSDN article useful:

How to: Upgrade Visual Studio SDK/VSIX Projects to Visual Studio 2012

Also, I believe you could check the following site: Open GAX/GAT, which contains the open-source version of the GAX/GAT projects which is also required by this extension. There you could also find useful information if you plan to migrate VS2010 extensions to VS2012.

Thanks for your guidance.

I know, But:

We created our projects based on WCSF and we can't go back.

All they work in vs2012, but we cannot add any WCSF item, because cannot enable WCSF guidance package.

However:

Are your help us, how we can add them from Web Client Software Factory 2010 Source Code.

Also, I cannot find relate between "Roadmap" and "WCSF"!

Hi,

As far as I know, the latest version of this VSIX package was designed to work with Visual Studio 2010 and according to the note in red in the Visual Studio Gallery Site it seems that there are no plans for new releases of this package in the future.

However, as far as I know, you can download the source code for this package in the Downloads page and modify it accordingly to your needs:

narimj — Thu, 17 May 2012 23:10:05 GMT

I understand its WCSF but its the SAME EXACT error. I am assuming that the guidance packages share some similar code which would cause this issue in both WCSF and SCSF. None of the links you provide are related to the issue I am experiencing. I guess I will create a new issue in the SCSF Issue Tracker and hope someone there can shed some light on this.

Hi narimj,

The workarounds proposed in this thread are targeted to the WCSF guidance. Therefore, the details of how to solve your problem with SCSF might be different for the ones described here.

As far as I know, there have been several discussions regarding this topic; but which approach should be used often depend of each particular scenario.

I believe the following threads in the SCFS Forums might be related to your problem:

Also, you might find the following work items posted in the SCSF Issue Tracker useful:

Anyone? Deleting the .gpState and re-enabling did not work for me. I had to check out an earlier version of my code and create new modules in there and transport them into my latest version.

The same issue is happening for me with SCSF 2010 and deleting the .gpState and re-enabling SCSF did not work I also get the same exception when I try to use the guidance to add a new business module.

I believe that this issue started happening once I upgraded the assemblies to the latest version of Enterprise Library (ver 5).

New Post: Multiple-Project Modules with Web Forms

nuchild — Tue, 10 Apr 2012 11:47:10 GMT

Hi Elixir,

I was unable to get to that portion of the guidance you mentioned in your post. Your link points somewhere else.

I don't think you can hook your seperate web applications as modules within an asp.net solution.

This wireing up is provided within the CWAB via the objectbuilder infrastructure.(as of now). There are folks working on using Unity (http://http://unity.codeplex.com/) as the Dependency Injection mechanism for WCSF. This should greatly reduce the code required.

To specifically answer your question,

What the WCSF/CWAB affords you is to build modules as seperate folders in your web application with their own dlls that will reside in the bin folder as well. These modules can still interact with each other via services. Your web pages/master pages/user controls must be written in such a way that the objectbuilder knows what to inject at runtime.

I suggest you start with the WCSF hands on labs. Go to the MSDN page at http://msdn.microsoft.com/en-us/library/ff648752.aspx and look for the hands on lab link. (It's for a previous release).

I think that this guidance has now really turned into a community effort and a new guidance (silk.codeplex.com) seems to have subsumed it.

I haven't had the time to look at it. But it looks promising and is based on asp.net mvc3.

New Post: Multiple-Project Modules with Web Forms

Elixir — Tue, 10 Apr 2012 06:36:01 GMT

Good day,

I was wondering if you could perhaps help me,

I was reading the guidance associated with the following: Composite Web Guidance

I was reading through the section titled "Define the Solution Structure for a Modular Web Application", particularily the section "Multiple-Project Modules". I seem to understand the basic concepts surrounding this, however I can't seem to figure out a reasonable way to allow this to work with my web forms in seperate projects.

I realise design time support for masterpages will not be supported here, my question however is how to use something like MEF(or another container) to allow me to deploy my projects (which include web form pages and code behind files) as completely independent into a folder and plug them into a solution, the guidance seems a bit unclear as to how to support this and whenever I attempt to import these modules I get run time errors. I've had this working successfully with MVC by exporting the controllers. I would appreciate your support, however I realise that you are an extremely busy people. If you could perhaps link me to a blog or a resource explaining this in detail I would be forever greatful. Thank you for taking the time to read this. To summarise I wish to achieve the following.

Create my web shell project using asp.net web forms (without silverlight or any client technology)
Create my modules which exist inside their own projects, which contain my aspx and aspx code behing pages as well as any dependent assemblies
I wish these pages to be exportable and importable by my shell.
If possible I'd like my module assemblies to be within their own folders as to not muddy my solution.

New Post: Issue with Property Injection, Policy Injection and the Service Collection

nuchild — Thu, 29 Mar 2012 08:08:00 GMT

Hi DCherubini.

Thanks for the response.

Actually, this issue has kind of disappeared. :)

I agree with your position. I may take the time to attempt to reproduce the issue if I have time and see exactly what was happening but

it appears it had to do with DLLs for my build of WCSFContrib.

I noticed I had both the objectbuilder.dll (entlib 3.1) and objectbuilder2.dll (entlib 4.1) DLLs in my project.

Apparently, My WCSF though it emits Entlib 4.1 libraries still adds the objectuilder.dll into the mix.

I intend to modify the wcsf files and rebuild so objectbuilder.dll is not included.

It would be nice to be able to download a build from this site that is actually meant for ent lib 4.1 from the get go.

As it seems project silk and by inference asp.net mvc (can we expect an asp.net mvc 4 without breaking changes?) is the new way to go.

Could you guys provide some guidance on migrating from wcsf to silk? Or maybe everyone's meant to develop on sharepoint? :)

Thanks
