I have been developing a .net web application for a while now. I had my application installed on a test server and everything was running smoothly. Now that the application is almost ready for deployment to end users, I obtained a brand new web server to host the application. I installed SQL server 2008R2, copied over my database and after a bit of messing about with conection strings and SQL logins, everything seemed to be working fine from debug. When I tried to install my app to the new server, I was prompted that I would need to install .net 4.0 which I then did. Gave the server a reboot and tried to install the app again - this time I got the following error before the install rolled back incomplete...

View 1 RepliesI was unable to upload files in a medium trust application and caught security exception.
If I change trust level to full it is working fine, but the hosting environment is set to run only medium trust application.
What are the settings to be done prior to upload files in a medium trust application.
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:

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."
