CSLA .NET

I think you got the source code for Rolodex that is too old – prior to Silverlight RTM.  IEditableObject interface that the error mentions got moved into a different namespace in RTM version.  Try to download the sample from this page:

http://www.lhotka.net/cslalight/download.aspx

The link is located in Samples column.  I would also download and compile CSLA itself just in case as well.

Thanks.

I was trying to get the rolodex project compiled but I am having the hard time trying to do it.

I have installed the silverlight sdk and tools for VS 2008 from here.

http://www.microsoft.com/downloads/details.aspx?FamilyId=c22d6a7b-546f-4407-8ef6-d60c8ee221ed&displaylang=en

I then opened up the Rolodex project and rereferenced the CSLA dlls.

I noticed then when I view any of the silverlight controls I get this error:

Could not load type 'System.Windows.Controls.IEditableObject' from assembly 'System.Windows.Controls.Data, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

and Building the project results in several misc errors:

*"ValidateXaml" task failed unexpectedly.

* 'TransactionalAttribute' could not be found 

* 'SerializableAttribute' is an ambiguous reference between 'System.SerializableAttribute' and 'Csla.Serialization.SerializableAttribute'

And some other errors. Some of these I can fix, though, it seems like I simply didn't install something correctly to have this many compile time errors running around.

The csla dll referenced was located in the Rolodex sample CslaLight\cs\Rolodex\CslaBin\silverlight\csla.dll

I am hoping something is glaring obvious and someone can help me get this sample up and running. Any thoughts greatly appreciated.

You need to reference DLLs because the ones in the solution may be out of date.  The sample is used to illustrate an approach, but you should always use the latest Csla DLL to incorporate up to date changes and fixes.  I would start there and see if the error goes away.

I seem to be having similar problems to Kyle, though I downloaded files from your link above.

I don't understand why I have to rereference the CSLA.dll in the Rolodex sample, when there is a CslaBin folder included in the solution? Why doesn't the solution point to those DLLs?

The main error I am getting is:

It looks like it might be related to this warning?

BTW, I attended your webcast. My only frustration was that I had not managed to get this going beforehand.

I am guessing that you do not have the latest version of SL runtime or SL toolkit on your machine.  Is this a possibility?  Or, maybe you are referencing .NET version of Csla.DLL instead of SL version?

Hi Sergey

I am getting similar errors while trying to compile any of silverlight samples.

Specific error i am getting is

Error 1 The "ValidateXaml" task failed unexpectedly.

This was being raised in silverlight project.
I was able to isolate error by creating brand new simple silverlight project. As soon as I add reference to CSLA.dll (CSLA light) to my project . I thought that may be I am using old CSLA.dll. I downloaded latest CSLA light solution and built it. Then refere the csla.dll from client bin in my new test silverlight project. I again got this error while trying to build. If i remove the reference, I was able to build it.
I am not sure what in CSLA.dll is breaking this.

I am not sure then.  I can see the file on my machine in C:\Program Files\Microsoft SDKs\Silverlight\v2.0\Reference Assemblies

Maybe you need to install SL dev. run time, but it should been installed with tools. My guess (and it is a guess), that there is something wrong with SL run time on your machine.  A quick test would be to create an SL application from scratch and see if you can run it.

Thanks for quick reply.

I have latest SL runtime and Silverlight tool kit.
SL Version: 2.0.31005.0
Microsoft SL Tools for VS 2008 SP1 (Version 9.0.30729.146)

I am definitely referencing CSLA light version. I downloaded both CSLA light(3.6.0 Beta 2a) and CSLA Windows (3.6.0 Beta 2a) again. Build CSLA Light solution and can see CSLA.dll in output 'ClientBin' folder.

I reference this dll in my silver light app and again got the same error.
