Hi,
The following exception occured when I tried to create an appdomain.
"System.Security.SecurityException: Request for the permission of type
'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
   at System.AppDomain.CreateDomain(String friendlyName, Evidence
securityInfo, AppDomainSetup info)
   at StoredProcedures.SPInsertTest()
The action that failed was:
Demand
The type of the first permission that failed was:
System.Security.Permissions.SecurityPermission
The Zone of the assembly that failed was:
MyComputer "

Let me explain what I have done.

1.I've created a class library by name TestApp which has a config file. I
have method called Readconfig which reads from the config and puts the value
in the file in some location. the readconfig method is called in the
constructor of this class.

2. I've created an exe which refers the above calss libray and creates the
object of the class present in it.

3. I've created a Managed stored procedure using the SQLServerProject in the
whidbey. The stored procedure has the following code.

            AppDomainSetup ads = new AppDomainSetup();
            ads.ApplicationBase = @"C:\SPTestExe";
            ads.ConfigurationFile = @"C:\SPTestExe\TestAppExe.exe.config";

            AppDomain ad = AppDomain.CreateDomain("TestApp", null, ads);
            ad.ExecuteAssembly(@"c:\SPTestExe\TestAppExe.exe");
       
when I install this stored procedure in yukon and run it, I get the above
mentioned exception.

Not able to trace out the reason.

Any help is gratly appreciated.
Thanks in advance,
