I recently raninto major problems when I added the Exception namespace to the
Project which has my DBML file attached to it. Once I renamed all the
Exceptions instances to Syste.Exception the project would not recoginize any
assembly which had been added to the project, even know they were all there,
this happened to the designer.cs file that is attached to the dbml file. I
have no clue as to why this is the problem.
 
Hello Alexander,

First off, I am sorry if these major problems turn out to be caused by
Microsoft products.

I am trying to reproduce the issue that the assemblies cannot be recognized
by Visual Studio even if they were all there. But I am stuck by the step
"adding the Exception namespace to the project". In .NET framework class
library, there is no System.Exception namespace. Is the "Exception"
namespace defined by your own code? If that, when we change it to
System.Exception, we may get an compilation error "'Excpetion' is a
'namespace' but is used like a 'type'" from a code line like 'Exception e =
new Exception("");". This is because "System.Exception" is a class and
"Exception" can also be regarded as a namespace in this case. The
resolution is to explicitly specify the namespace "System" when we use
"Exception". For example, "System.Exception e = new System.Exception("");
". If I misunderstand you question, please let me know more detailed
repro-steps or send an example project to my mailbox (e-mail address removed)
so that I can have a clearer picture.

Have a good day!

Thanks

Figured out the problem!

The problem is that I have a namespace root called NTKSDataLayer I have a
class Logger that is defined in ths name space With in this calss the
Exception class is refrenced mutiple times.

Here is the example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

//using Snippet.Exception;
namespace Snippet
{
public class Class1
{
public Class1()
{
try
{
if (1 != 2)
throw new System.Exception("Whoops!");
}
catch (Exception ex) //This line won't compile
{

}
}
}
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Snippet.Exception
{
[global::System.Serializable]
public class DALException : ApplicationException
{
//

// and
//
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncscol/html/csharp07192001.asp
//

public DALException() { }
public DALException( string message ) : base( message ) { }
public DALException( string message, System.Exception inner ) : base(
message, inner ) { }
protected DALException(
System.Runtime.Serialization.SerializationInfo info,
System.Runtime.Serialization.StreamingContext context ) : base( info,
context ) { }
}
class Exception
{
}
}
