Hi All

I am quite new to Guidance Automation Toolkit(GAT).

Ourcompany have a full fledged guidance package based on GAT Jun 06 which works fairly well on VS 2005.

Recently I joined this group in my company & I got the job to migrate this package from VS 2005 to VS 2008.

I have both versions of GAT July 07 as well as Feb 08 .

Initially when i started migrating I got stuck up somewhere with build errors. Now I am able to register my guidance package . When I try to create a new solution with this package, it works fairly well till WizardPages & upto some actions but after reaching a point where we are calling some arguments from recipe in t4 template file , it fails.

The error is as below

Microsoft.Practices.RecipeFramework.ActionExecutionException: An exception occurred during the binding of reference or execution of recipe CreateSolution. Error was: Action TestT4ForStringName failed to execute:
Exception of type 'Microsoft.Practices.RecipeFramework.VisualStudio.Library.Templates.TemplateException' was thrown..
You can remove the reference to this recipe through the Guidance Package Manager. ---> Running transformation: System.NullReferenceException: Object reference not set to an instance of an object.

When i tried to debug the t4 template , the arguments in the template file was showing error message :

DOProjectName threw an exception of type System.NullReferenceException

When i looked inside in the inner exception was _COMPlusExceptionCode = -532459699

Can anybody give me an idea why this error is coming.

I would like to mention that our factory is quite a big one which generates all layers of N-tier architecture , supports WCF,

It has got many Custom Wizard Pages, Custome Actions & custome Arguments

Hi Jose,

First of all thanks for replying,

I would like to inform you that Ihave sorted out the issue as of now.

It may seem strange to you that I had Debug=true for all my t4 templates & this was the problem I suppose.

Probably you might be knowing that VS2005 comes with CLRDebugger (generally in Program Files\Microsoft Visual Studio 8\SDK\v2.0\GuiDebug\DbgCLR.exe), but in case of VS2008 , as far as I know, there is no CLRDebugger so thatmight be the reason for the failure. As soon as I removed Debug=true, it worked perfect.

Please correct me, if I am wrong. It would really help me in understanding the GAT/GAX.

But now I am struggling with the same package's setup issue.The previous setup, even after converting to VS2008 & replacing all references with releavent VS2008 references, is still targetting VS2005. I haveposted the same issue in another thread here Any help in this regard from your side will be highlyappreciated.

Thanks & Regards,

Haritosh
