I have deployed a website on server (Windows Hosting).
I am getting the following error:
Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityException: Request failed.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
I have searched and found that the solution is to add the following code to webconfig file
<trust level="Full"/>
But this produces the error
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: This configuration section cannot be used at this path. This happens when the site administrator has locked access to this section using <location allowOverride="false"> from an inherited configuration file.
Source Error:
An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Line: 24
On Line:24 in webconfig file is
<trust level="Full"/>
How to resolve this ?
I am using
Target Framework: .NET Framework 4.7.2
Edit
You can check for that Code Access Security is already set to Full.

I am trying to re-direct from Classic asp application to a .aspx page for a File upload. I am receiving following error. Any input of what this error is can be really helpful.

I tried the URL on browser and get following errors
CS0234: The type or namespace name 'Transactions' does not exist in the namespace 'System' (are you missing an assembly reference?)
I have placed my system.Transactions.dll in bin folder. Made sure that Copy to local is true and also have Using system.Transactions . But still unable to see what is causing this issue.
I'm in the process of migrating a client site to an Azure VM (stop gap until we rewrite to move to Azure Proper). The problem that I have is that there is a problem somewhere and I can't see what it is. When I run up the site I get the usual yellow screen of death...
Runtime Error
Description: An application error occurred on the server. The current
custom error settings for this application prevent the details of the
application error from being viewed remotely (for security reasons).
It could, however, be viewed by browsers running on the local server
machine.
Details: To enable the details of this specific error message to be
viewable on remote machines, please create a tag within
a "web.config" configuration file located in the root directory of the
current web application. This tag should then have its
"mode" attribute set to "Off".
Notes: The current error page you are seeing can be replaced by a
custom error page by modifying the "defaultRedirect" attribute of the
application's configuration tag to point to a custom
error page URL.
I have had this many times before in such situations, so I edited the web.config file to look like this...
<system.web>
<customErrors mode="Off" />
(other stuff)
</system.web>
... and the same message came up. I recycled the app pool and even restarted IIS but I still get the same message, it's as if the VM just doesn't care what I put in the config file.
I've added 'localhost' to the bindings so I can view it on the server directly and I get this instead...

Has anyone else come up against this before?
I'm at a loss what to do.
I found the answer to this one. The web.config file was referencing a child file which wasn't present. This is quite a gotcha if you can't use localhost based debugging.
Your system.web tag is not properly closed:
<system.web>
<customErrors mode="Off" />
(other stuff)
</ system.web>
Should be:
<system.web>
<customErrors mode="Off" />
(other stuff)
</system.web>
when i host my website on my local machine on IIS 7 my website runs correctly, but when i upload the website to my hosting space online the error:
<sessionState mode="InProc" cookieless="false" timeout="20"/>
(comes up in red)
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
comes up. could you guys please help me out?
Notes i use multiple web.config files and no i cannot delete them
Much appreciated
The clue is here: "This error can be caused by a virtual directory not being configured as an application in IIS."
Depending on who your hosting provider is, check that your website is running as a Web Application.
The tag is allowed only at the root level. If you are using multiple web.config's ensure that you haven't copied this tag into any other config file.
Also ensure that your virtual directory root is marked as an application.
I want to publish my ASP.net based web page on Windows 7 machine.But,I got continually an error inside the below code.
<sessionState mode="Inproc" timeout="30"></sessionState>

How to get rid of this problem?
The clue lies in the error message:
This error can be caused by a virtual directory not being configured as an application in IIS.
Have you created an "Application" for it in IIS? Does the website's node in IIS look like a folder or a globe?

Please help me !
To avoid seeing useless error messages like the one you posted, I use an errorlog database table and additional exception handlers. In general, when an exception occurs, I catch the error, write the error to the error log and then just reraise it to let the system handle it further. Then, when I receive an errorpage like this one, I can check the error log for possible exceptions.
In this case, I suspect that it's a configuration error, though. So it's likely that the system did not even manage to get inside your code or possibly the exception handling itself would fail too, simply because it can't connect to the database.
Possible causes: no access rights to the database, missing modules, invalid configuration, not enough access rights, routing errors, application not set in IIS and many, many other possibilities. To solve these errors and to prevent this happening in a production environment, always deploy to a test environment first, so you can check for any errors and other problems.
As Joel Coehoorn commented, adjust web.config first. But additionally, deploy the web application to a local, clean test environment first! Then you can more easily check any problems without disturbing the production environment. (Use a virtual machine if you can't afford a second test system.)
