Microsoft Application Blocks and Medium Trust??

Michael Howes

I'm upgrading a VS 2003/.Net 1.1 ASP.Net application to VS 2008/.Net 3.0

The application uses an older version of the Microsoft Data Blocks for
database access. The version in the Microsoft.Appli cationBlocks.Da ta.dll
is 2.0

The call to SqlConnection.O pen() fails after I upgrade to .Net 3.0
The application runs under a tweaked version of Medium trust. After the
upgrade and the call to .Open() fails if I change the trust to Full the
call works.

Do I need to upgrade the version of the Application Blocks we are using
or is there a way to get this older version to run under medium trust in
..Net 3.0??

The call works in .Net 1.1 medium trust
The call works in .Net 3.0 full trust
It fails with .Net 3.0 medium trust

thanks

Moving up to EnterpriseLibra ry 4.0 is probably the next logical step.

But I think its strange you're getting the issue in the .Data DAAB.

...

Wait, are you one 3.0 or 3.5? It's either EnterpriseLibra ry 3.1 or 4.0. I
don't know if you're in VS2008 but youre using 3.0 compatability.

This gets more complicated.
I don't know where the Microsoft.Appli cationBlocks.Da ta.dll comes
from. It's just in a bin folder in the project.
I think it came from "Enterprise Library for .NET Framwork 2.0 -
January 2006".

I just installed "Enterprise Library May 2007" which I think is
version 3.1. After install I did not fine a dll called
Microsoft.Appli cationBlocks.Da ta.dll

I don't understand the problem either. I do know that if I make the
call to SqlConnection.O pen() it fails (after upgrading to .NET Framework
3.0) in Medium trust and works if I change to Full trust.

..

Wait, are you one 3.0 or 3.5? It's either EnterpriseLibra ry 3.1 or 4.0. I
don't know if you're in VS2008 but youre using 3.0 compatability.

I'm building (upgrading to) .NET Framework 3.0
I think the version of the enterprise library is "Enterprise Library
for .NET Framwork 2.0 - January 2006" which is *before* 3.1

But as I just mentioned I just installed EnterpriseLibra ry 3.1 and
don't see the dll we are using.

any help appreciated

This example uses the DAAB 2.0.

This example
http://sholliday.space s.live.com/blog/cns!A68482B9628 A842A!176.entry
uses the EnterpriseLibra ry 3.1.
Dll Name?
Microsoft.Appli cationBlocks.Da ta.dll is a compiled version of the DAAB 2.0.
(Pre EnterpriseLibra ry)
//Quote//After install I did not fine a dll called
Microsoft.Appli cationBlocks.Da ta.dll//Quote//
That is correct.
Microsoft.Pract ices.Enterprise Library.Data.dl l will be the new one.

This is not a super trivial upgrade. The syntax is different. Use the
projects above to figure that out.
The issue is that you need to pay this price to get at the right level of
Enterprise Library for VS2008.
With the 2 projects, you can see a DAAB 2.0 version (for 1.1 code) and a
(upgraded newer version) of the EnterpriseLibra ry with a VS2005 (2.0/3.0)
code.

That's alot better than nothing.
The EnterpriseLibra ry is much more mature. And deals with the security
issues alot better.
You basically need to view the DAAB as a deprecated library, since its been
superceded by EnterpriseLibra ry.
..........

Have a good weekend, I'm out.

thanks!

it looks after a quick 15 minute glance that the old SqlHelper class
has been mostly replaced by the Database class. If that's true, I have a
lot of work ahead of me.
a lot of the calls look similar, PrepareCommand, ExecuteReader, etc

You don't see what you're looking for because the structure of Enterprise
Library has changed. I strongly recommend you take some time to read the
part of their documentation that deals with Data Access.

Also, if you're using Visual Studio 2008, why _not_ use .NET 3.5 features
where they are useful? Neither .NET 3.0 nor .NET 3.5 make any changes to
..NET 2.0 code - they only add features. You will still be running the 2.0
CLR in either case, so why not get current?

Url Posting Fails / Medium Trust

I am trying to do a URL post using HttpWebRequest, but it fails because I am hosting on Network Solutions, and their servers are all medium trust. Apparently HttpWebRequest doesn't work on medium trust. Is there any way to do URL posting in a medium trust environment? I'm hoping I don't need to switch hosts because of this.
