Build error - bin folder

[Mark]

ive recently installed the telerik tools in my site, but keep getting this error when i try and build the solution.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(3607,9): warning MSB3061: Unable to delete file "C:\Sites\MySite\bin\Telerik.Web.UI.xml". Access to the path 'C:\Sites\MySite\bin\Telerik.Web.UI.xml' is denied.

i shut down VS and ensure the bin folder has read-only removed, but this error keeps coming back every time.

how do i eradicate it ?

Hello,

Could you please try following this steps and let me know if the issue still persists

1) Close the Visual Studio
2) Stop the IIS if the site is deployed on it
3) Close all other programs that eventually use “bin\Telerik.Web.UI.xml”
These 3 steps are to ensure no one is locking the file for writing. Then, you can
4) Check the security of “bin\Telerik.Web.UI.xml”, to make sure you have write permissions
5) Now copy “...\Telerik.Web.UI.xml” to the “\bin” folder of your project.

I hope this helps.

Greetings,

Further to this, I've experienced this when trying a Rebuild in a Telerik MVC 3 Application on the Telerik.Web.Mvc.xml file.

To solve, I've browsed to: C:\Program Files (x86)\Telerik\Extensions for ASP.NET MVC Q1 2012\Binaries\Mvc3 and added full control to my user account. This solves the issue.

It seems that when the Telerik Extension copies the file to your project folder, your user account isn't given permission to delete the file when running a Rebuild.

Cheers,

This issue has now become more serious as it stops the compiler.  In prior releases it didn't.  It's not reasonable to stop IIS each time we compile and it doesn't solve the problem anyway.  The only way I've found so far to get around it is to "Clean" the project TWICE then compile it.

Hello Joan,

Thank you for sharing your experience.

This should not in any way be related to our assemblies, but is probably a deployment quirk of some kind. Could you share some additional details around your current deployment scheme and project setup? That way I, or possibly someone else from the community could give you a hint on how to get things working better on your side.

All the best,

I think I know why the file is locked.  If I open the project and compile I don't have a problem.  I don't use the Casini web server, I use IIS.  If I run the site outside of Visual Studio, then IIS locks the file and the compiler has a problem with it.  The file is a 7MB documentation file that I don't think should be copied to the BIN folder at all.

I think this would explain why some people have a problem and some don't.

It's non stop over here also - every build I get that error - and then have to rebuild a second item and them it works.

Is there ANY way of stopping that automated file copy during building?

I'd suggest just switching over to using IIS Express or the Visual Studio Develiopment server for debugging. That should generally avoid any issues of the kind.
