C#, Linq2Sql, .NET 2.0, SQL 2005 Express
When I run the following code I get a InvalidCastException unable to cast of type System.Byte[] to System.String
This does not occur on all rows in the table i.e. this code runs fine soemtimes.
I checked there are no columns in the table that linq declares as SYstem.Byte[]
The stack trace says the exception occurs on the linq statement and when I F11 into the code the GetProject is never called the exception occurs before this method is called.
So I think it is Linq framework bug.
This has got me stumped? any ideas?
