I am walking through the steps.

The first problem is that when I select Create Test Certificate it defaults to a .pfx key.   I deslected the Sign The Assembly checkbox, yet it keeps pulling up the _TemporaryKey.pfx and asks me to Enter password.

How can I get it to ignore .pfx and create a .cer ?

I now get a new error when trying to publish...it will not go away even if I deselect the Sign the ClickOnce manifests checkbox and/or the Sign the assembly checkbox in the Signing tab.

The error is:

"Error 1 The ClickOnce manifest for XAML Browser Applications must always be signed. You must specify properties: SignManifests (value set to True), ManifestKeyFile (with the name of your key file) and ManifestCertificateThumbprint (hexadecimal thumbprint value in SHA-1 format, of key file). Alternatively, you may use your IDE's Publish Wizard or Signing options."

I've tried using the Publish Wizard but I do not see any options that refer to Signing...

I got it to work!   I had to rollback some other changes I made to the project.  Then I followed these instructions step by step and now I am able to run my Full Trust application over the web in a browser!

Thanks for all your help!!!!

How did you create the .cer file? In the steps, when he does "Copy to File" it creates a .pfx. No .cer.  So I'm confused on where that file comes from.

thanks

This is really helpfull

Gr8........ It works for me.

Thanks a lot.....

I have been looking for a solution from last 3 months....

once again thanks....

Hi

I'm getting the error: "The ClickOnce manifest for XAML Browser Applications must always be signed. You must specify properties: SignManifests (value set to True), ManifestKeyFile (with the name of your key file) and ManifestCertificateThumbprint (hexadecimal thumbprint value in SHA-1 format, of key file). Alternatively, you may use your IDE's Publish Wizard or Signing options." when trying to use the certificate from store. I opened the new, clean application, and keep getting this error. When using .pfx file that VS added for me, the app builds and publishes, but is not accessible from other machines in my LAN. I guess this is expected, otherwise there wouldn't have been this article. But what am I doing wrong in exporting the certificate?

Thanks in advance...

Thank you, I will see what exactly I messed up there.

Anyway, I got everything to work the way it was after registering the certificate (.cer) on client machines (which I somehow didn't think of yesterday...)

I am walking through the steps.

Though I got the following error...

ERROR SUMMARY

Below is a summary of the errors, details of these errors are listed later in the log.

* An exception occurred while determining trust. Following failure messages were detected:

+ User has refused to grant required permissions to the application.

thanks,

Now Its working on my system only. It shows the same error, run on some other system. Now what can I do for this.

Hello maxim,

This is run only in the system where the application is created. Its not runs in the client system.

so pls tell me the solution for this. Its very helpful to me.

Thanks

Hello maxim,

It is only run in the system where the application is developed. It's not run in the client system.

so pls tell me the solution for this. Its very helpful to me.

Thanks

Hi I do all of your instruction but i cant able to deploy, while deploying the following error shows,,

Error 2 The ClickOnce manifest for XAML Browser Applications must always be signed. You must specify properties: SignManifests (value set to True), ManifestKeyFile (with the name of your key file) and ManifestCertificateThumbprint (hexadecimal thumbprint value in SHA-1 format, of key file). Alternatively, you may use your IDE's Publish Wizard or Signing options. TrustedXbap

pls tell me how to rectify this...

Under "File export wizard (step B):", you're telling people to distribute their private key (i.e. export this certificate with the private (signing) key) so that users can run their apps.  This opens up the possibility of malicious users signing their own applications with such a private key, resulting in fully trusted code running from a malicious source.

Always keep private keys private, and please use strong passwords on them!

Post was just informative... :)

post provided exactly what i wanted ... Thank You.

very cool

greate, thanks a lot!

very helpful.sent this link to my friends.

Thanks a lot..

Hi,

This really helped a lot for a start. However in real time scenarios the client would not like to install the certificate in the end users machine. So how can we automate this process in XBAP ??

Thanks

This has been very helpful but I fear the last step is going to be an issue for me.

How can I manually deploy the files given that I use the Visual Studio developer version of IIS which doesnt exist until runtime so I cant deploy to it.

Thanks!

Thank you very much for this post, it was very helpful. Good job.

I use you method to solve my problem.

Thanks a lot!

But there is still a problem.

I can visit the WPF page after I publish it to a server becuse I install the certificate.

But I can NOT visit the WPF page via a computer which desn't install the certificate.

So, if there are any method to avoid certificate installation in the client computer? Or install the certificate automatically?

Thanks.

Great Post! Star Lee: We posted on our blog how to create an automatic certinstall application. Give it a look ... www.managescope.com ... If this is a serious blog faux pas pointing someone to this, mea culpa :)

Vivien Dracon:

I read your blog.

Thanks a lot!

I've this page very usefull.

I'm new to running XBAP's and this realy helps. I'm having a run-time issue, after ClickOnce step related to a dual http communications bewteen the XBAP and a wcf service. The problem seems to be that once an XBAP is using the callback channel, through the "http://+80/Temporary_Listen_Addresses/some_address" I cannot launch any other instance of the XBAP. Any suggestions?

Thanks

Ooops.

My email address is lshahar@harris.com

Thanks

Just wondering if someone could tell me what happens in 12 months after deploying (or creating the certificate). Will the application stop working? Will I (the developer) need to re-release the application with a new certificate and get all the users to reinstall the new certificate?

Hello

I tried your steps. I am happy that it is working, but only in my PC.

But when i open the hosted url from networked pc then its not going to open.

I installed the certificate file on my networked pc but still the same.

So what i need to do for accessing the application from network?

Thanks

XBAPs are deployed using ClickOnce and default to run in a sandbox, because of this you might encounter

First , that is a great article , thanks a lot =)

Im got it the same problem.

Import the certificate in "Trusted publishers" too.For me that works.

This is very helpful but what steps does the end user have to go through when they browse to my app?  Do they have to modify any of their browser settings?  There are quite a lot of steps there to follow, I want the end user to just be able to say yes or no.

Great Article. unfortunately it didnt work for me

I still get the error message

Wow.  that was incredibly annoying to get this to work. i found a post that said to add the certificate to both the TrustedRootCertificationAuthorities <strong> and</strong> TrustedPublishers

btw - How can be able to install the certificate automatically

Hi Maxim. Thanks for this post. Unfortunately, it's not working for me. I followed all steps exatly several times with no luck. Please help.

P.S. I'm trying to write file on the local filesystem and always I get error:

System.UnauthorizedAccessException: Access to the path 'C:\date.txt' is denied.

Great Article! I have been reading a lot of articles on how to deploy and get it working on the client side and have been pulling my hair out. Anyhow, It worked for me. Thanks for the easy tutorial on how to set it up.

I have a question for you. Can I set up the XBAP app to launch executables on the server-side when the client clicks on something?

Great Article, thank You. Questions : 1) How can I extend use of the certificate ?

2) How can I make a easy installation ?

I could be wrong but I think there's two things wrong with this tutorial.

1/ You say that we should choose 'Yes, export the private key' but you need to choose 'no, don't export the key' to get the .cer file.

2/ I needed to install the certificate under 'Trusted Publishers' not 'Trusted Root Certification Authorities' fot it to run on a clean client machine.

Like I say, I'm no expert but this is what I had to change to get it to work. Thanks for the info though, much easier than the way I was doing it before!

Great Thanks, dear last poster!!! :)

It works!

Don't stop posting such stories. I like to read articles like this. BTW add some pics :)

I tried for days to get my XBap to not throw the Trust error. Caspol would work on occassion, but not always. This is the best article by far, and step by step instructions work great!.

One caveat though like another said. Choose "No, dont export the key" in order to see the .cer extension.

turns out you may also have to run Caspol

And on some machines the Cert appears to have no effect.  Caspol is more reliable actually.

And for that to be run the user must have admin priveledges or an admin must log on to the machine.

I hope to figure how to automate remote delivery/run of caspol.

SURE MAKES ME MISS THE GOOD OLD DAYS WHEN WE HAD PHP, PERL, AND BASH.

HA HA!

Ah, great! This cleared up some confusion I'd heard.

Oddly, when the trusted publisher's certificate expires, Trust is not granted! How come?

I tried HTA and it's very easy to get through

My project has some references to some third party dll. and when I publish it my localhost and run it, IIS always return me, unable to find those dlls... How come u looks never meet this issue?

Jesus loves you

This is fine for same machine(server), but whenever accessing from another machine(client) it shows same error "Trust not Granted". Please let me know the solution for this problem.

Install certificate on client machine as well

What if the certificate used to sing the application gets expired. I received the same error again. How to handle this in deployed application?
