Ok so I don't know why this happens but I've had a few times where VS 2008 doesn't ask me if I want to target 3.5 and I've gone on about my business not realizing the error. So as a reminder to myself and others out there if you see this error, right click on your solution and go to properties. Under the build section make sure you're targeting 3.5 and save yourself some headache.

Hi toadkicker,

it's nice to hear I'm not the only one to do this mistake. Thanks for the reminder, maybe once we have had this error more than n^n times we'll start our projects setting the target framework, just in time to have some new headaches with other errors.

[Edit] Also remember when upgrading the framework to keep changes made to the compiler and assembiles sections in web.config to prevent further headaches with custom modules targeting 3.5. [/Edit]

Best regards,
Dario Rossa

Hi Dario,

I got this problem, too.

But I got it in a productiv dnn installation.

I wanted to test the LinqThings4Sale sample from Michael Washington.

http://www.adefwebserver.com/DotNetNukeHELP/LinqTutorial/

So I do nothing than upload his compiled version.

So do you think that there is an compilation error in the sample from Michael? 

 

Full Error report:

Error: LinqThings4Sale is currently unavailable.

On that tutorial it reminds you:

Note: In order to run this module on another DotNetNuke site, you need to install ASP.NET 3.5 on the server and modify the web.config of the DotNetNuke site:

Change: the <system.codedom> section to:

<system.codedom>
<compilers>
<compiler language="vb;vbs;visualbasic;vbscript" type="Microsoft.VisualBasic.VBCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" extension=".vb" warningLevel="4">
<providerOption name="CompilerVersion" value="v3.5"/>
<providerOption name="OptionInfer" value="true"/>
<providerOption name="WarnAsError" value="false"/>
</compiler>
<compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4">
<providerOption name="CompilerVersion" value="v3.5"/>
<providerOption name="WarnAsError" value="false"/>
</compiler>
</compilers>
</system.codedom>

Change: the <assemblies> section to:

<assemblies>
<add assembly="Microsoft.VisualBasic, Version=8.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
<add assembly="System.DirectoryServices, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
<add assembly="System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
<add assembly="System.Management, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
<add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
<add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
<add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
<add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
<add assembly="System.Data.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</assemblies>

Hi Michael,

thanks for your quick response.

I have already copied the changes in the web.config before.

Is there anything else I can do?

In DNN 5.0 is there an out of the box support for LINQ?

When is it comming out?

 

Best regards,

Alex
