Thanks for replying David.
These are the DLLs that I imported. The application runs fine on my
local machine, the error is only happening when the trust="medium" aka
a medium trust environment.
Here are the DLL's my application is seeing:
DbLinq.dll
DbLinq.MySql.dll
MySql.Data.dll
I'm getting the following error message:
{"Type 'DbLinq.Data.Linq.Sugar.IDataMapper' has no implementation"}
at DbLinq.Factory.Implementation.ReflectionObjectFactory.Create(Type
t)
at DbLinq.Factory.Implementation.ReflectionObjectFactory.Get(Type
t)
at DbLinq.Factory.ObjectFactoryExtensions.Get[T](IObjectFactory
self)
at DbLinq.Factory.ObjectFactory.Get[T]()
at DbLinq.Data.Linq.DataContext..ctor(IDatabaseContext
databaseContext, MappingSource mappingSource, IVendor vendor)
at DbLinq.Data.Linq.DataContext..ctor(IDatabaseContext
databaseContext, IVendor vendor)
at DbLinq.Data.Linq.DataContext..ctor(IDbConnection dbConnection,
IVendor vendor)
at AppUI.Models.Linq.MySqlDBTest..ctor(IDbConnection connection)
at AppUI.Controllers.AccountController.ValidateLogOn(String
userName, String password)
I am trying to edit the ReflectionObjectFactory's Create(Type t)
method to somehow anticipate this error and deal with it accordingly,
but I don't fully know what the create method is trying to accomplish.
Here is the code modification that I am attempting:
public object Create(Type t)
{
//warning - the Activator.CreateInstance below was
throwing unerported exceptions (as of 2008June).
//So - let's add two future rules:
//1) for know types from DbLinq, don't load via Activator.
//2) surround all Activator calls with try/catch block.
if (t.IsInterface)
{
IList<Type> types;
try
{
if (!Implementations.TryGetValue(t, out types))
throw new
ArgumentException(string.Format("Type '{0}' has no implementation",
t));
if (types.Count > 1)
throw new
ArgumentException(string.Format("Type '{0}' has too many
implementations", t));
return Activator.CreateInstance(types[0]);
}
catch (ArgumentException ex)
{
if (ex.Message.Contains(" {\"Type
'DbLinq.Data.Linq.Sugar.IDataMapper' has no implementation\"}"))
{
//DbLinq.Data.Linq.Sugar.IDataMapper idm;
DbLinq.Data.Linq.Sugar.Implementation.DataMapper idm = new
DbLinq.Data.Linq.Sugar.Implementation.DataMapper();
return
(DbLinq.Data.Linq.Sugar.IDataMapper)null;
}
}
}
return Activator.CreateInstance(t);
}
