Dear All,
I am using asp.net 3.5 with Microsoft Reporting Service (RDLC).
My Application works fine in local machine. But when I upload my application in
my real application server it shows the following error message
My real application server is a shared asp.net 3.5 hosting provider.
Can anyone advice to resolve it.
Server Error in '/' Application.

I have tried with crystal report too.
It shows the error as follows

If not you have to check if you have the required permissions sets to load your appdomain within the distant server and you have to configure this by setting the updoamain policy
// Set a new AppDomain PolicyLevel.
PolicyLevel policyLevel = PolicyLevel.CreateAppDomainLevel();
// Set a new application domain.
AppDomain mydomain = System.AppDomain.CreateDomain("MyAppDomain");
// Create a new permission set.
PermissionSet permSet = new PermissionSet(PermissionState.None);
// Add permission to execute code to the permission set.
permSet.AddPermission(new SecurityPermission(SecurityPermissionFlag.Execution));
// Give the policy level's root code group a new policy statement based
// on the new permission set.
policyLevel.RootCodeGroup.PolicyStatement = new PolicyStatement(permSet);
// Give the new policy level to the application domain.
mydomain.SetAppDomainPolicy(policyLevel);
// Try to execute the assembly.
try
{
// This will throw a PolicyException if the executable tries to
// access any resources like file I/O or tries to create a window.
mydomain.ExecuteAssembly("Assemblies\\MyWindowsExe.exe");
}
catch (PolicyException caught)
{
Console.WriteLine("PolicyException: {0}", caught.Message);
}
