28/01/2011 Leave a comment

Ok you start developement with .net framework 4.0 and possibly try to deploy your site to iis first time and getting this error :Unrecognized attribute “targetFramework” when deploying asp.net 4.0 Because you did not configure your iis run with .net framework 4.0.

For do it you have to change your path to

C:\Windows\Microsoft.NET\Framework64\v4.0.30319

that execute command of

aspnet_regiis.exe -iru

if you already do this and getting this error you should better to check your site application pool for correct .NET framework version chosen.

Application Pools->Select yours -> Basic Settings -> And change .NET framework version

Thats it folks.

The given expression is never of the provided warning.

When you try to getting type of Generic variable “T” you get this warning.Here is the sample :

class CauseWarning
{
    public void make<T>(T value)
    {
         if (typeof(T) is Test)
         Console.Write("Something"); 
    }
}
public class Test
{
}

Here is the solution:




class CauseWarning
{
    public void make<T>(T value)
    {
         if (typeof(T).IsAssignableFrom(typeof( Test)))
         Console.Write("Something"); 
    }
}
public class Test
{
}

Type.IsAssignableFrom Method Determines whether an instance of the current Type can be assigned from an instance of the specified Type.true if the c parameter and the current Type represent the same type, or if the current Type is in the inheritance hierarchy of c, or if the current Type is an interface that c supports. false if none of these conditions are the case, or if c is a null reference.
