May 15, 2010Error Description while browsing the website under IIS "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." Initially I deleted the virtual directory, created again, set the permission to anonymous, set the browse and execute permissions, no solution. Then after doing many trials, I found out the basic problem reading the error "not allowed by the security policy". In web configuration file if we set the security policy to Fully Trusted, then problem solved and application working fine. or Set the trust level to the main configuration file in he "C:WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGweb.config"

Full Trust Doesn't Seem To Work With WebMatrix Web.config File?
Mar 30, 2011I've been told by my host that I need to enable FullTrust in my webmatrix website because I keep getting an error. (BUT, I have used a different host, and everything on my site works perfectly with them without modification). Anyway, I used the code my host suppllies in their KB, but that just generates a different error. So I looked up full trust on google and used about 5 different code samples to enable full trust but they all generate errors! even the ones on MSDN. And googling "Full Trust WebMatrix" doesn't really bring anything helpful either.
How can I successfully add full trust to a web.config file that is made using WebMatrix?

Is It Possible To Prevent File Access Outside The Website Folder While Keeping Full Trust
Jan 4, 2011Setting the .Net trust level to Medium on a site will ensure that no code can access files outside the application directory.
I have an ASP.Net site that must run in Full Trust. I have configured my website in IIS to use its own Application Pool Identity [URL].
Currently it is possible for scripts/code in this app to read files outside of the application directory. This occurs because by default, accounts that are a member of the BUILTINusers group are able to read most files on the system, including c: and c:windows. It appears that Applicaion Pool Identity accounts are also members of BUILTINusers.
Is it possible to prevent file access outside the website folder while keeping Full Trust?
Configuration :: How To Give Full Trust To Activex Control By Programmaticallytrust To Activex
Jul 30, 2010Currently I have written the Activex Control for RFID USB reader and calling that one in ASP.NET web application. The Activex Control is working fine when I will give the full trust permission for particular IIS URL in
1. Open Control Panel > Administrative Tools > .NET Framework 2.0 Configuration
2. Expand Runtime Security Policy > Machine > Code Groups > All_Code
3. Right Click All_Code and click New...
4. Create a new code group, I named mine MyProject_FullTrust_Zone
5. Choose the URL condition type and specify the path on the network where the apps will be deployed.
6. Choose Use Existing permission set, and set it to Full Trust.
Alternative way of giving permission for an Activex Control is
1. Open Visual Studio Command Prompt
2. Run the command caspol -machine -addgroup 1. -site <ip address> FullTrust Doing this it works fine.
Whenever my web site will open, it will ask the user to give permission for the Activex Control using Allow or Cancel Button in browser. This type of functionality I have seen some web site which takes input from the user to allow the ActiveX Control.
Configuration :: Server Trust Level And Twitter Application Interface - Error "System.Security.Permissions.SecurityPermission, Mscorlib"
Oct 14, 2010There seems to be an issue with the "Trust" level when executing within a "Cloud" environment. In order for the following app to work it needs a trust level of at least "Medium." This web app is developed using VB.NET 3.5, and Visual Studio 2008. The app works perfectly on my local sever but when deployed/published to the "Cloud" it returns the error: System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I have added all 4 required values, ConsumerKey, ConsumerSecret, OAuthToken, and OAuthTokenSecret to the web.config file in the "appSettings" section of the "configuration"
[Code]....
If found that by going to [URL] and signing into the account that is using the application, then go to the "Settings" page, go to the bottom of the page and click on the "API" menu option. Once the API page appears you will clik on the button "2", Register An App. On the right side on the new page, you will see a button "View Your Applications." If you have previously registered your app, click this button, If not fill out the appliction for a new app. Now at the View your Applications page, select the app you want to get the authorization keys for where is says "Edit Details". Now click on the button to the right that says, "Application Detail." Here you will find your Consumer Key and your Consumer Secret Key. On the right side of this page you will see the menu option "My Access Token", click it and you will find your oauth_token and your oauth_token_secret keys! Not that you have all the keys, put them in the "appSettings" section of the web.config file. Add "Dim twConn As New TwitterVB2.TwitterAPI" at the top of the page.
I then created a subroutine where I pass in the Tweet:
[Code]....
This code works great in an enviornment that allows at least a "Medium" trust level. However it appears that many of the "new" hosting envrionments such as "Cloud Hosting" and others do not allow this trust level automatically!However if the trust level is less than "Medium" on your host you will likely receive the error message: "Twitter Returned: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed." If anyone has found a fix for this "Trust Level"

Configuration :: Webservice WebConfig File Not Recognized By Windows App?
Mar 2, 2011I have created a webservice, which debugs fine with no errors, and published this on my localhost server for testing.
I have created a windows app which calls the webservice but am hitting problems as soon as I reach the point where the webservice tries to connect to its database.
The connectionstring is held within the web.config file of the webservice as
>><connectionStrings>
<add name="MyConnectionName" providerName="System.Data.ProviderName" connectionString="server=MyServerName; database=MyDataBaseName;uid=MyUser;pwd=MyPassword;"/>
</connectionStrings>
and called within the code by using the statement
>> System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionName"].ConnectionString
, and as I said before, this works perfectly when debugging the webservice application directly.
However, the windows application is not seeing the connection properly, if I use the statement as above I get a debug error stating that it is a NULL reference. If I change it to
>> System.Configuration.ConfigurationManager.ConnectionStrings[0].ConnectionString
I no longer get a debug error, but the connection is not made. On testing the above code it believes the name for connection 0 is "localSqlServer" and in both the web app and the webservice the error below is returned.
>>An attempt to attach an auto-named database for file \MyServerMyDirectoryMyProjectMyProjectApp_Dataaspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
why the windows application see's the correct connection string code as null? Is there additional security I need to add for the web.config file to be accessible? Or does the connection strings need to be relicated within the app.config of the windows app?
Both applications are written in C# and I use Visual Studio 2010, ASP.Net version 4.0.30319

Detect The Current Trust Level For Application
Jan 23, 2011I found this code:
AspNetHostingPermissionLevel GetCurrentTrustLevel() {
foreach (AspNetHostingPermissionLevel trustLevel in
new AspNetHostingPermissionLevel [] {
AspNetHostingPermissionLevel.Unrestricted,
AspNetHostingPermissionLevel.High,
AspNetHostingPermissionLevel.Medium,
AspNetHostingPermissionLevel.Low,
AspNetHostingPermissionLevel.Minimal
} ) {
try {
new AspNetHostingPermission(trustLevel).Demand();
}
catch (System.Security.SecurityException ) {
continue;
}
return trustLevel;
}
return AspNetHostingPermissionLevel.None;
}
Get current ASP.NET Trust Level programmatically):
but for C#, and would like to have it for VB.NET. Any chance of someone expert in both VB.NET and C# that can translate this to VB code?
I tried myself and got the following VB.NET code but it generates an error inside my VWD:
Private Function GetCurrentTrustLevel() As AspNetHostingPermissionLevel
For Each trustLevel As AspNetHostingPermissionLevel In New _
AspNetHostingPermissionLevel() {AspNetHostingPermissionLevel.Unrestricted, _
AspNetHostingPermissionLevel.High, AspNetHostingPermissionLevel.Medium, _
AspNetHostingPermissionLevel.Low, AspNetHostingPermissionLevel.Minimal}
Try
New AspNetHostingPermission(trustLevel).Demand()
Catch generatedExceptionName As System.Security.SecurityException
Continue Try
End Try
Return trustLevel
Next
Return AspNetHostingPermissionLevel.None
End Function
These parts seems to be wrong:
New AspNetHostingPermission(trustLevel).Demand()
and
Continue Try
Obviously, need to be handled by someone fluent in both C# and VB.NET and can spot the errors in VB.NET

.net - WebPermission Exception Even Though In Full Trust?
Jan 16, 2010I'm trying to do what I thought was a simple HttpWebRequest (the code is deep inside a dll so I can't give a small code snippet, but it should be relatively simple), but I'm getting a security exception:
System.Security.SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I've checked and everything is running with Full trust, and have tried setting this in the web.config. But I've no idea what could be creating the error.
C# - Setting Trust Level To High In Web.config Makes Application Run Slower?
Jan 11, 2011We had a UAT and Production version of a .NET web application. UAT was taking around 5 seconds to run a particular operation while Prod was taking 35+ seconds.
This even happened when pointing both web applications at the same database and putting them both on the same machine.
The culprit was finally found to be the following entry, which was in the Prod but not UAT web.config
<trust level="High" originUrl="" />
why this would cause such a significant performance degradation??
