Using Configuration Manager - .net-4.0

some of my web applications write to the disk on the web server. The paths change depending on location, prod and dev, etc. I used to store the paths in web.config under configuration / appSettings like:
<add key='PDFOutPutPath' value='C:\Temporary_Web_Files\PDFTempDocs\'/>
And then get them like this:
path = ConfigurationSettings.AppSettings('PDFOutPutPath')
Now in .Net 4, I get compile warnings about this being depreciated, so I found some instructions telling me to add a configuration file, move my values to it like so:
<configuration>
<appSetings>
<add key='PDFOutPutPath' value='C:\Temporary_Web_Files\PDFTempDocs\'/>
</appSettings>
</configuration>
and use configuration manager like so:
ConfigurationManager.AppSettings( 'PDFOutPutPath' )
However, this does not work. I'm not sure if I'm supposed to be using the configuration manager for this or not - If not, where do you put stuff like this? I have System.Configuration referenced, so this in not my issue.

So it appears the instructions you followed were a bit misleading.
You do not need a second file, you should delete the app.config file. You can place all of the configuration values in the web.config. Just make sure the config items are in the <appSetings> node. But you should continue to use the ConfigurationManager class within the code to access the values.

How to use multiple locations for configSource in config file for WCF Client

Our application will act as client for different WCF-services in the future. At the moment we consume only one WCF-Service. Our config-file for the application is set up using configSource-attribues at the moment:
<configuration>
<system.serviceModel>
<services configSource="services.config"/>
<bindings configSource="bindings.config"/>
<behaviors configSource="behaviors.config"/>
<extensions configSource="extensions.config"/>
</system.serviceModel>
</configuration>
Is there a way to use multiple files for e.g. the bindings section? We would like to have each binding for a particular WCF-service that we consume in one file. So we would need to point the bindings section to multiple configSources.
Any help would be great.
Looks like you can't separate the configsections into different physical files. So we ended up merging e.g. all bindings in one file.

Failure to obtain lock using Lucene and Sitecore

I'm trying to implement Lucene search in Sitecore. Using the default Sitecore.Search implementation, I should be able to get a reference to the index defined in my config file and call index.Rebuild.
I tried using the RebuildDatabaseCrawlers script from the AdvancedDatabaseCrawler, but everytime I call Rebuild, it fails.
The error I receive is:
Lock obtain timed out: SimpleFSLock#C:\sites\MySite\Data\indexes\__mysite\write.lock
I've tried changing permissions (including giving Everyone full perms), restarting databases and IIS, all to no avail. I've also tried stripping my search configuration section down to the bare minimum, with the same result.
Unfortunately I don't have any visibility into what the index.Rebuild() method does, as its inside the Sitecore.Search assembly.
The issue ended up being related to configuration.
Specifically, when trying to remove all superfluous Sitecore.Data.Indexing references from the configuration files after determining that i didn't need both Sitecore.Search and Sitecore.Data.Indexing, I had commented out the following line:
<configuration>
<appSettings>
<add key="Lucene.Net.FSDirectory.class" value="Sitecore.Data.Indexing.FSDirectory, Sitecore.Kernel"/>
</appSettings>
</configuration>
That needs to be there.
Try to adjust the permissions for c:\Temp for your app pool user, e.g. Network Service
You can also try to do the same for: c:\windows\microsoft.net\framework\{version}\Temporary ASP.NET Files

Problem with type of service in ServiceHost directive in wcf service

I am developing a simple wcf service for test. When I test this service with my local IIS 7.5, then it works properly. But when I host it in web IIS, I receive this error:
The type 'WcfServiceLibrary1.Service1',
provided as the Service attribute
value in the ServiceHost directive, or
provided in the configuration element
system.serviceModel/serviceHostingEnvironment/serviceActivations
could not be found.
And my ServiceHost is:
<%# ServiceHost Language="C#" Debug="true" Service="WcfServiceLibrary1.Service1" %>
Please help me resolve this problem
Because I couldn't find this suggested in any of the questions I looked through for this, adding my case here:
I had this problem when I manually changed the namespace in the file MyService.svc.cs, and did not change the Service name in the corresponding file MyService.svc - turned out that it needed to be Service="namespace.classname".
Try using the assembly qualified type name.
This is [Fully Qualified Type Name], [Assembly]
Where [Fully Qualified Type Name] is, in the most common cases YourNamespace.YourType
And [Assembly] is, in the most common cases YourAssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null
It gets more complicated than this (generic types, nested types etc) - but unlikely to be so in your case.
If your application is using the default build options, then I'm going to hazard a guess that the directive should be something like this:
<%# ServiceHost Language="C#" Debug="true"
Service="WcfServiceLibrary1.Service1,
WcfServiceLibrary1,
Version=1.0.0.0,
Culture=neutral,
PublicKeyToken=null" %>
Although you'll probably want to get rid of the newlines there.
Also, make sure your dll has actually been deployed
I had the same issue only when publishing my service but it worked locally.
It turned out to be that the service was referencing a DLL that wasn't being deployed. It's a super special case because it was a system dll (System.Web.Helpers) and thus the project didn't even have a reference to it and thus the "Copy Local" wasn't set to true.
IIS defaults to expecting to see the svc file in the virtual directory, and the binaries inside a bin folder (as marc_s commented).
However, the default build configuration for WCF Library projects is to build inside a bin/Debug folder (or bin/Release). You can change the Output Path to 'bin/' on the project properties Build tab.
Changing this resolved this error for me today.
I had this same problem after I deployed a working service to a new location (new site) in IIS. In inetmgr under the Default Website tree, I hadn't right-clicked the new site and selected Convert to Application - all working now!
Finally my problem solved.
I removed the service directory in my host and created a new virtual directory in the host space. Then I copied my service in new directory where I created it.
Now I can browse the .svc file for service and my client will consume the service.
I don't understand why this problem occurred! I am a little confused!
The answer marked as answer is very difficult to understand. In fact, although it led me to solve my similar problem, I don't know if that's because I accurately understand what the writer was meaning.
I was finding if I pointed an IIS application on my development machine to the actual project directory in which resides the web.config, MyService.svc, and bin folders necessary for the WCF Service Application it just wouldn't work, and was throwing this error. This is despite quadruple checking every setting and ensuring that things were equivalent to other simple, working WCF Applications.
Ultimately, I solved the problem by publishing to a different directory rather than depending on the project files and directory themselves.
Perhaps it was because the files were open in Visual Studio as I was trying to run the WCF application through IIS? I don't know, but the Visual Studio provided localhost:59871/... was working. I don't know if that instance is using the project files or a temporary published version.
Check whether namespace and class written in "Service" of "SeviceHost" is correct .It should be Service="namespace.classname" .
Another reason for this issue is often when a wcf service is moved from one directory to another, and the svc file has not been updated... easiest solution is to double check your .svc file and make sure the service definition is defined correctly.
As I can't up vote #jeromeyers answer at the moment, I want to add that this is the solution that I found for this issue.
Someone had copied and pasted a svc file and associated contract and code files to a new project, but they had not updated the namespaces and class names everywhere. Very frustrating tracking this down as it started with this error :
" name was started with an invalid character. Error processing resource 'file:///C:/...
<% #ServiceHost "
when trying to right click on the .svc file and doing "View in browser".
Even though this is slightly different than the question (not web iis): I got here through search because I was getting this error trying to Debug my service -- if you have multiple services inside a single solution, this error will occur if the solution in question is not built yet, and therefore the DLL not created when you try to access it. So to anyone out there make sure if running locally that the entire solution is built!
had this problem running a test project that was embedded in my solution.
I had to view in browser, then copy that link to a new service reference (delete the old one) then paste it in rather than using the discover utility button in the service reference.
Strange as well, after looking and trying others suggestions, i was still getting the error saying the:
The type ', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found.
Sure we all get large project with a lot of DLLs. Turned out some of the older components in my solution were targeting .Net 4.5, and newer dll were build with 4.5.1. When the 4.5 dlls referenced the 4.5.1 dlls .... Not sure why i was the happy little guinea pig to be the first on my team to find this. While the fix was obvious and easy enough, just all the dlls to target the same .Net runtime.
Just wish Visual Studio would notice DLLs within the same solution should all target the same .Net runtime and generate a warning/error when building especially with we have a solution and a project reference and the runtimes don't match...
Be sure your compiled dlls are moved to service(IIS directory)
directory.
For example, sometimes Jenkins doesn't move them automatically.
I had the same issue when i uploaded my working localhost service to a new location on host.
I create a new Virtual Directory and published my Service to it via Visual Studio(FTP). Problem Solved.
It happend the same to me and the solution was creating a forder named "bin" and place the dll inside of it. Then, refresh the website on IIS and that's all
I had this problem too, and what did the magic for me was to restart the IIS.
This is a very weird error.
First time hosting WCF Service Application, in IIS ?
Many have solved their problems one way or the other. However if everything is your solution is correct and your error is about host your app in IIS, then ensure your physical path in IIS when you add your website is pointed to the "bin" directory of your solution as seen below in the screen shots.
Please look at https://msdn.microsoft.com/en-us/library/ms733766(v=vs.100).aspx
You need to do 2 things to be able to Host the Service on IIS, or even on Visual Studio's itergrated IIS_EXPRESS.
1) Update the Web.Config to include ServiceActivations
change:
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
to
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true">
<serviceActivations>
<add service="API.Service1" relativeAddress="Service1.svc"/>
</serviceActivations>
</serviceHostingEnvironment>
2) You need to create a directory called App_Code in the root directory.
You now need to move the Service (ex: Service1.svc) from the root directory into the App_Code directory.
So you will have App_Code\Service1.svc
If you browse the Service
http://localhost:63309/Service1.svc it should work.

Why is this class library dll not getting information from app.config

I am developing a custom HttpHandler, to do so I write a C# Class Library and compile to DLL.
As part of this I have some directory locations which I want not hard coded in the app, so i'm trying to put it in the app.config which I've used before.
Before this has worked by just going building the app.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="Share" value="C:\...\"/>
</appSettings>
</configuration>
And then obtaining this in code like:
var shareDirectory = ConfigurationManager.AppSettings["Share"];
But when I compile it and put it in the bin folder for the webservice, it keeps getting null for shareDirectory, probably because it can't find app.config. So how do I make sure this is included so I don't have to hard code my direcotry locations? I notice it will essentially after compiled we get the assembly.dll and the assembly.dll.config which is the app.config file, so it's definetly there in the bin folder!
That is because your web service uses web.config
You're probably confusing the scope of your class library.
Remember, your config, be it web.config, or app.config, is the config present in the HOSTING application. In this case your hosting application is the WebService, hosted of course by IIS, so your config file is the web.config.
If you had a console app which somehow used that class library (though probably not in an http handler context), then the config would be the app.config in the console app, not the app.config in your class library.
You need to put the configuration in your web.config file, not in assembly.dll.config: .NET does not (by design) read assembly.dll.config files.

how can i setup my nhibernate library to work in both a web and console application?

on the web application, I am using a NHibernate helper that looks up the session that was opened in a httpmodule (and committed there also).
<property name="current_session_context_class">web</property>
In the console application, what do I do?
Your options are: "call" & "thread_static". Have a look at this for more detailed explanation on all available contexts:
http://nhibernate.info/doc/nhibernate-reference/architecture.html#architecture-current-session
In order to have your library work for both a web and a console application you have two options:
Based on a application setting in the App.config and in the web.config have the Session Factory built accordingly by setting the current_session_context_class property manually in the code and remove it from the hibernate.cfg.xml file.
Include a in the web application's web.config and in the app.config of the console application. This way you can have the current_session_context_class property set to different values. If I am not mistaken the in the web.config and in the app.config overrides the values of the hibernate.cfg.xml. If I am wrong then you will just have to include in the web.config and the app.config the complete and remove the hibernate.cfg.xml file from your library.
