Resetting properties in web deployment project based on custom build config file

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :Windows Application

I'm trying to create a general build environment for multiple projects that can take a some command line parameters and execute a build based on a custom config file.

The problem I am having is after I read in the config parameters with MSBuild.Community.Tasks XMLQuery, which works fine, I can't get aspnet_complier to see these parameters.

I keep getting "error MSB3462: Either MetabasePath or VirtualPath must be specified."

 Here is my project file:

<Project InitialTargets="PreMessage" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> 
   <Target Name="PreMessage">
    <Message Text="Building..." />
 <Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tas

Web deployment project - web.config section replacement does not add remove tag


I have a web application that is actually installed as a component of a third party site.  In some configurations, I need to remove certain connection strings and re-add them.  I'm replacing this web.config section with a xml file that includes the following:

      <remove name="MyOverridenConnection"/>
      <add connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyDb;Data Source=MyServer" name="MyOverridenConnection"

For some reason the remove tag is left out during the substitution and I end up with the following in the installed config:

      <add connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyDb;Data Source=MyServer" name="MyOverridenConnection"

Is there any way to issue removes in replaced sec

Could not load file or assembly - Web Deployment Project



I have the following projects in a solution :

- A Web Application

- A Class Library

- A Web Deployment project

The Web Application compiles and run fine when I don't go through the Web Deployment Project. However when I try to use that, I get the following error:

Error 1 An error occurred creating the configuration section handler for hibernate-configuration: Could not load file or assembly 'NHibernate' or one of its dependencies. The system cannot find the file specified. (F:\Folke\Folke.csproj_deploy\Release\web.config line 4) 1 1 Folke.csproj_deploy

"An error occurred creating the configuration section handler for hibernate-configuration: Could not load file or assembly 'NHibernate' or one of its dependencies. The system cannot find the file specified. (F:\Folke\Folke.csproj_deploy\Release\web.config line 4)"

This is the beginning of my Web.config:

Site File Structure, Folders, Learning project, subweb, web.config

I am just learning asp.net.  I purchased an "ASP.Net 3.5 web programming in C#" book, which I like allot.  I am on chapter 3 and want to complete a shopping cart exercise from the book.  I have to create several folders and files.  The exercise has the files and under the root directory and a few folders below that.  I already have a site that I've been learning on.  Can I create a subfolder on my site and put all the files in there?  Like the subfolder is the root of the project.   Here is list of Folders and files... Code/CartItem.cs Code/Product.cs Data/Cars.mdb Images/car.jpg Cart.aspx Order.aspx Web.config ................................ On my website I want to create a subfolder to keep alll the files in, as so... ShoppingCart/Code/CartItem.cs ShoppingCart/Code/Product.cs ShoppingCart/Data/Cars.mdb ShoppingCart/Images/car.jpg ShoppingCart/Cart.aspx ShoppingCart/Order.aspx ShoppingCart/Web.config ................................ Can I have two web.cong files?, one in the subfolder?  Or do I have to use the single, web.config file in the root directory of the site?  Are there any other pitfalls or trouble I might get into setting up my file structure like this?  Anything I should be aware of? Any thoughts or advice would be appreciated. Thanks, Mike

Setting of sharepoint 2010 custom WCF service "web.config" file for both HTTP and HTTPS



        I have created a custom SharePoint 2010 WCF service that is deployed to 14\ISAPI\MYService folder. The issue i am facing is that this service should be accessible from all Web applications, that can be HTTPS (i.e. SSL) enabled or normal HTTP. If i am making in web.config file for web application that has HTTPS enabled, then it fails for Web applications having normal HTTP configuration. My requirement is that when this WCF service is deployed it should accessible from all web applications that can be HTTPS or HTTP both. I went through number of blogs and tried whatever option they had suggested but none of them worked for me :(. Here are some of the blog that i tried:-

Xml File Methods and Properties

Method and Properties of XmlTextWriter class:
The XmlWriter class is a base class that outputs an XML data structure. It has methods to sequentially write XML elements in a proper hierarchy to create an XML file or other types of output streams. The System.Xml namespace provides support for the XmlWriter. It must be imported to the ASP.NET page with the directive

<%@ Import Namespace="System.Xml" %>

The XmlTextWriter

XmlWriter is an abstract class that is implemented as an extended XMLTextWriter class. The XmlTextWriter writes a sequence of XML nodes one element at a time. Output can be written to an XML file, although other streams of output data can be produced. It can create a new file or overwrite an existing file. Its non-cached writing techniques provides very fast generation of an output stream.

Multiple MSIs from one deployment project


We have several .NET based products for which we need to generate multiple MSI files to allow for multiple instances of the same app to be installed on the same machine.  For instance, we might have a single server running version of the app that are pointed at either test or QA databases, or may use the same server box to deploy the product for multuple clients.  (So, for instance, our web server might have separate installs of the same code in different locations for product names "Client A test", "Client A QA", "Client B Test", etc., where the only real differences are in the web.cionfig files that are not overwritten by the install of a new version.)

Right now we simply have a deployment project for each named variation of the app.  This works, but is likely to become a maintenance mess as the number of instances grows.  We'd like to be able to maintain only a single deployment project and script the creation of multiple MSIs, one for each product variation, after the build of a baseline MSI.

As I understand it, this should be acheivable by building the MSI, then for each possible instance, making a copy of the MSI and giving it a unique ProductCode and PackageCode; this way Windows should recognize each instance as a unique application.  I've done this (as well as changing the produc

web deployment project (WS_deploy) on VS2008


I am building a asp.net webservice in VS2008 and the web service compiles and debug fine. The project should be using : Net 3,5

 I have

  1. VS2005 and VS208 installed
  2. .Net 1.1 - 3.5
  3. WebDeploymentSetup for VS2008 (and most likely a version for VS2005 as well)

But when I add a web deployment project the fun stops. The .WS_deploy project will not compile and I cannot find any precompiled output.

vs2010 web deployment project restarts w3svc even when restartwwwservice = false


We've updated some of our projects from VS2008 to VS2010.  When these projects are deployed the w3svc is restarted on the target machine, even when restartwwwservice = false in the vdproj file.


This was a problem in 2008 until SP1 (http://forums.asp.net/p/1300097/2534736.aspx).  Does this same problem exist in VS2010?


This is a major problem for us -  we need to be able to deploy projects without restarting IIS.


I've tried creating a new web deployment package and setting the restartWWWService field to false, but this still does a restart when it's installed.


Has anyone come across this problem in VS2010?
