How to maintain a Unity container reference in WCF

Posted By:      Posted Date: September 29, 2010    Points: 0   Category :WCF

I'm configuring validation application block from Enterprise Library 5 to use validation rules from the web.config file over a WCF call.

The problem is as new calls to the WCF service occur, validation application block is spending a considerable amount of time reading the validation configuration before validating. So my first call to the service which checks if a certain username is available to use (this method also does validation on the username before checking database) take a long time, but every call after that is pretty much instant. Then when I press F5 in my browser and try again, it takes a very long time to setup (read the config validation rules) again.

I read in the Developers guide to Ent Lib 5 that I should maintain a reference to the default Unity container that is setup and use this container to resolve the references. It suggests that I should use a custom extension to the InstanceContext to achieve this but does not give any examples.

How do I do this? Does anyone have examples? I am thinking holding onto a reference to the Unity container could solve the initial speed issues of hitting the service for the first time.

I should mention that I

Unity container works within Asp.net project but not within class library it calls.


I have a solution with an asp.net project and several class libraries.  I am using Unity 2.0 in all the projects.  Unity 2.0 seems to work within the HelpfulQuiz web asp.net project, but not within the HelpfulQuizCore class library it utilizes.  I've spent several days trying to figure this out and would appreciate your kind assistance.  Here is the error:

Enabling Users to Maintain SharePoint Content

When SharePoint is installed as a corporate intranet, there is a considerable amount of effort involved in maintaining the content to keep the site relevant. As we discussed in the first few parts of this series, SharePoint has many built-in features to reduce the burden on the site administrator.

Some areas of the site usually contain less-dynamic information. Internal memos and corporate policies are common examples of this information. One option for this information is to post these documents in a document library. Documents in a library are often stored in a few different formats: Word, Acrobat (PDF), or HTML. Each of these formats has its drawbacks.

Tab container rendered with visibility:hidden - This was reported over three years ago.



Here is (more) code that demonstrates the issue.  If the control in the host page is removed the tab control renders correctly.  Otherwise it is rendered with the visibility attrubute set to hidden as reported in the above link.  Is this broken or am I doing something wrong?

Re-positioning an HTML container with javascript onresize with a Master page.


I have an HTML <div> container that I float to the right of a gridview.  When the browser window is maximized, it looks fine.  When minimized, the gridview positions below the floating container and most of the data is pushed off the bottom of the browser - you have to scroll down to see it.

If I position the floating container above the gridview it looks fine in a minimized window, but looks real bad when maximized.

What I want to do is use a javascript: onresize event to re-position the floating container up or down depending on the window.inner.width AND do it with a Master/Content page structure AND do it for only the one page where needed.

I can capture the onresize event and display the window dimensions but haven't figured-out how to do it with a Content page that still uses the Master page.  I think I'm having a very "thick" week...

reference from menubuttons to text parts in article on the same page


Hi, I'm searching now for hours but couldn't find it.Cry

In my menu i have several buttons which (by a <a href..) should go the a part of an article that is in the same form.

Menu button : What is a database should go to the page default.aspx and in there is an article published.
A part of this article is having a piece of text about "what is a database"

Menu button: how to make a query should go to this same article in the same page but then to the part that is have the piece about the query. The next could be an example of what i'm doing:

    <li><a href="default.aspx ?????>what is a database</a></li>
    <li><a href="default.aspx ?????>what is a query</a></li>

Where my question marks are, there should be a connection to that particular piece of text.
In each article part there is an ID="text1" and the second part id="text2"

How shoudl i do that, Should i use a question mark.
Please give me some guidance how to structure the <li> statement or a pointer where I can read about it.

Registering controls of current assembly object reference NOT set error


Hi There,

I have created a simple ASP.net Web Application (2.0) and have added a web user control.

Now in my page I have added this control but I have registered like this,

<%@ Register Assembly="WebApplication1" Namespace="WebApplication1" TagPrefix="Custom" %>

Which means I want to access all the controls in my current Web Application project

Then I have added my user control like this,

<Custom:MyUserControl ID="MyUserControl1" runat="server" PublicProperty="Hello" />

Every thing is fine but when I execute the project, NO control on my user control gets "instantiated" and thus I receive error "Object Reference Not Set"

Note that My Control has,

1) Public property PublicProperty as String

2) 1 Label control

In Load Event Handler I am setting Text property of Label Control to PublicProperty. Here object reference NOT set error occurs (which means Label control is NOT initialized).

I don't want to register my control using Src, TagPrefix etc. Any ideas?

LINQ Sorting After Goup w/ Table Reference


Having a little trouble here.  I am taking a table (Articles) and grouping all the results by the key that references another table (ArticleSectionCategories).  I then want to sort these results by the OrderBy field of the referenced table (ArticleSectionCategory.OrderBy).  This is what I am using right now but it is not working.  Any thoughts?

Custom tool error: Failed to generate code for the service reference 'CompanyService'. Please che


A little background because I feel I have an out of the ordinary architecture in place and don't know if this is contributing to the problem. 

We have an existing ASP.net application that is undergoing expansion.  The new functionality is all written in Silverlight 4.  As part of that expansion I gutted all the old Linq to SQL and put Entity Framework 4 into place.  To do this I created a standard .net Class Library and added my edmx files there.  Naturally, the business entities created by this cannot be used in Silverlight.  So I created a Silverlight Class Library and added all the business entities to that Silverlight Class Library as linked files.  I changed the name space to be the same.

So I have the following assembly / namespaces

Company.Project.Dal.csproj / Company.Project.Entities (.net 4 class library)

Company.Project.Entities.csproj / Company.Project.Entities (SL4 class library)

With this architecture I was able to share my business entities with my SL enabled web services, my asp.net projects, my silverlight projects.  Really it's a beautiful thing.

Once this was done I added "message" classes to Company.Project.Dal and again shared them with the other entites using linked files.  These messages are things like MyObjectRequest; they are class
