CrmSvcUtil Attribute Constant Generator Extension

A recent question on the CRM MSDN forum made me realise that as far as I can see, no-one has yet created a CrmSvcUtil extension to generate attribute constants. So I did.

Download the CrmSvcUtil extension at codeplex: CrmSvcUtil Generate Attribute Constants.

To use the extension:

  1. Copy GenerateAttributeConstants.dll into the directory containing CrmSvcUtil.exe
  2. Run CrmSvcUtil with the following parameters:
CrmSvcUtil.exe ^
/codecustomization:"GenerateAttributeConstants.CodeCustomizationService, GenerateAttributeConstants" ^
/codewriterfilter:"GenerateAttributeConstants.FilteringService, GenerateAttributeConstants" ^
/url:http://servername/orgname/XRMServices/2011/Organization.svc ^
/out:Attributes.cs

The baseTypes parameter is optional and can be used to override the base types for entity classes which is needed if you have previously generated the wrapper classes with an extension (eg. Microsoft.Xrm.Client.CodeGeneration.CodeCustomization).

To use the generated attribute constants:

Contact contact = new Contact();
contact.Attributes[Contact.firstnameAttribute] = "Michael";
contact.Attributes[Contact.lastnameAttribute] = "Palmer";

CRM 2011 Developer Tools target location for Visual Studio 2010 vs Visual Studio 2012

The path for the targets is different for the Developer Toolkit for Visual Studio 2010 and Visual Studio 2012. This can cause errors when loading the Visual Studio project in the form of the error

The imported project “C:\Program Files (x86)\MSBuild\Microsoft\CRM\Microsoft.CrmDeveloperTools.CrmClient.targets” was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.

or when attempting to deploy the CrmPackage project from Visual Studio 2010 as the error

or when attempting to deploy the CrmPackage project from Visual Studio 2012 as the error

depending on the combination of Visual Studio version, installed Developer Toolkit version and previously installed Developer Toolkit versions.

In order to resolve any of these, make sure that the correct targets are referenced in the CrmPackage.csproj file:

  1. In Visual Studio, right click the CrmPackage project and click Unload Project.
  2. Right click on the CrmPackage project and click edit CrmPackage.csproj.
  3. Find the line starting with “<Import Project="$(MSBuildExtensionsPath32)\Microsoft\CRM\" and replace it with the correct path from the list below.
  4. Save and close the file.
  5. Right click on the CrmPackage project and click Reload Project.
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\CRM\Microsoft.CrmDeveloperTools.CrmClient.targets" />
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\CRM\Microsoft.CrmDeveloperTools.12.targets" />

Every now and then I randomly receive the error above when attempting to access CRM. Usually, restarting both the Microsoft Dynamics CRM Asynchronous Processing Service and Microsoft Dynamics CRM Asynchronous Processing Service (maintenance) resolves this but when it doesn’t, we do the following to resolve the issue:

  1. (Re)start the Microsoft Dynamics CRM Asynchronous Processing Service and Microsoft Dynamics CRM Asynchronous Processing Service (maintenance) services
  2. In a command window, run
    Microsoft.Crm.Tools.WRPCKeyRenewal.exe /R

    in the CRM Tools folder (C:\Program Files\Microsoft Dynamics CRM\Tools\ by default)
