CustomBinding binaryMessageEncoding error, Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service.

this is an Issue about the WCF Bindings. By default, if you use wshttpbinding or httpbinding, The http channel will use the Text based encoding which is not very efficient in terms of the network transfer. however, you can combine one custombing, just pick up the binaryencoding which is been used by tcpbinding, and httptransfer as the transport channel.

you can create one customBinding like this,

</binding>
</customBinding>

if the service is hosted in IIS, and the anonymous access for this folder has been turned off. you may get the follow error when you try to access the svc. even just the wsdl access.

erver Error in '/DemoWCF' Application.

Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service.

Tutorial , Firebug , Free Commercial IE httpwatch alternative

HttpWatch is a great Commercial Tool to capture the Http traffic, enable admin to do the user end http analysis. like check the Cache is correct, client did get the Gzip version response. If you are looking for a free alternative. FireBug for fixfox is my top choice. Here is a basic tutorial one Firebug.

Install Firebug on Firefox.
Click tools->add-ons, search firebug. click to install the add-on and restart firefox.

After loaded the firebug, Open Firefox, press F12 or click add-ons to turn it on.

View the Http Request /Response Header. Click the dropdown arrow to enable the traffic capturing.

When you access Wikipedia mainpage, http://en.wikipedia.org/wiki/Main_Page, you will see the resource get requested to web servers. and the timeline.

click one url , i.e the first one. you can tell the server is apache, the wiki used Cache heavily. here the cache could be squid or varnish. the we do get the gzip version response.

scroll down, you can see the request header the firefox is sending out.

If you press Shift and click the refersh in firefox. you will see that the firefox tell the edge server to reload th request and never pickup the cached version.

in the HTML tab, click the pointer to a object like the logo here., you can see the img url and css styles.

after I located the Entity framework connection string, Unable to load the specified metadata resource. continued reading the professional asp.net mvc 2 to page 48. When I try to run the details page. /controller/details/validid
get the following error,

Then I did some research. Though we added the assembly System.Data.Entity into our project. which means that those assembly are only for Runtime reference. For Compile time reference, We have to add the reference to System.web/Compilation/Assemblies in web.config, then the csc will pick up this settings

Troubleshooting Entity framework connection string, Unable to load the specified metadata resource.

I was reading the Book called Professional MVC 2 , following the tutorial to Page 44.

When I run the application, /Details/id, which will invoke the Entity framework to do a DB query. No luck, get an strange error.

Line 37:         /// Initializes a new nerdDinnerEntities object using the connection string found in the 'nerdDinnerEntities' section of the application configuration file.

Then I check the web.config. the connection string is there.

So the runtime will read some resource file embedded in the Assembly. So are the name correct?

I just run a ILDASM NerdDinner.DLL /out:a.il

c:\NerdDinner\bin>ildasm NerdDinner.dll /out:a.il

Here, for those resource file, Pay attantion to the filename. this is no Assmebly name as the prefix.
Models.NerdDinners.csdl Instead of NerdDinner.Models.NerdDinners.CSDL which is defined in the web.config

so remove the nerddinner in web.config , that’s the trick to fix the problem

550 5.7.1 Unable to relay for name@domain.com System.net.mail

one day, the ASMX web service can’t send email any more. When I run a cordbg and attached to the W3wp. turn on to catch all unhandled exception, “ca e”

first, get CDO Exception. then continue, get the error like

550 5.7.1 Unable to relay for name@domain.com

then I change different TO Address, no luck , still the same error.

the Service just a wrapper of the System.net.mail to send email , and uses a local SMTP server.

it looks like that’s a fat finger issue. When I turn on the Relay setting of the smtp server.

I get the following settings as shown.

which means that all relay will be denied. unless you specify it in the exception list.

then just switch it back.

When I run the cordbg and attach to the dfsvc.exe . the stack trace tells somthing different. no signature

all these errors are caused by one fact that the filed downloaded by click once are “Broken”, either file is deleted or the signature is incorrect.( for example, you download the file from http://servera/, then next time same file is downloaded from the loadbalancer. http://loadbalancer/ or http://virtualIP/

Fix is easy. Go to the default once click app file location.
windows 7 will be C:\Users\[userid]\AppData\Local\Apps\2.0
xp or 2003 C:\Documents and Settings\[userid]\Local Settings\Apps\2.0

delete all those folders in that path.

try to install and run the app again, the issue will disappear. It looks like the pre-determined state of click once is broken.

IE8 JavaScript is disabled / not running after remove McAfee folder ACL

One day, JavaScript will not run on my IE . how to make sure javascript works? here is the step to run the helloworld test. [ Open a webpage, like google.com, then put “ javascript:alert(“hello world”) “ in the address bar , and click enter. you should get a prompt window if java script works.]

finally, I find it was caused by the McAfee ACL setting. Here is the story,

I just want to disable the McAfee temporally, the easy way is to remove all ACL on the folder, then nobody else can access the folder. for sure, the service fail to start when I reboot the PC.

Then when you try the helloworld test. Nothing returns. Javascript is disabled, it might be caused by Mcfee indirectly or directly.

to fix it,
1. Add back the ACL.
2. The jscript.dll might be unregistered. run “regsvr32 jscript.dll” in the runbox to make sure it is registered
