C# - Setting Trust Level To High In Web.config Makes Application Run Slower?
Jan 11, 2011
We 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??

My web application is composed of several Visual Studio projects. It currently runs fine under high trust level (<trust level = "High" />). When I try to run it under medium trust level, I get this error:
Security Exception

What is the best way to identify the problem and convert the application to run properly under medium trust?

I 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

Error 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"

There 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"

My ISP recently has migrated my app to a new platform. The app has now to be parked in a root subfolder, say site1, rather than at the root.
The main page can still be accessed via [URL] is now located at /site1/default.aspx. Subfolder pages however cannot be accessed correctly anymore since the url includes now subfolder name "site1" ie
[URL]
instead of
[URL]
This of course breaks page referencing.
Despite multiple requests, I have not yet obtained an answer so far. Question: Is there a simple way to strip away string "site1" from the url, preferably at the web.config level? I know this can be done programmatically at the page level, to clean up page references (>30 pages). In addition, this could entail further compatibilty problems between the deployment version and the local development site.

what Medium Trust level is ?And what does it mean :
"More and more ASP.NET hosting providers are enforcing a Medium Trust Policy on their servers.Therefore it is important to make your website work (as much as possible) in environments where medium trust is enforced."

CWe've internal application written in ASP.NET, AJAX, SQL 2005. The problem is that sometimes response time (post back) is raising up to 10-30 second for some reson. The only way to make it faster is to restart browser (IE). Then it works really fast.
I have no clue what is causing this. Maybe it's viewstate, browser cache, browser memory clogging - I DON'T KNOW. The only thing I know is when I shut and reopen browser it's working fine. If I leave it open and come back in an hour or two it's really slow.

The following code snipped doesn't work, because AppSettings[...] is readonly!
