To deploy our custom web application inside ISV folder of CRM 2011 we need to follow the below steps

Make following changes in the web.config

<configuration>
<configSections>
<remove name=“crm.authentication“ />
</configSections>
<system.web>
<httpModules>
<clear/>
</httpModules>

……………………

And after deploying the application within the ISV folder, place the following dlls within its bin folder

• AntiXssLibrary.dll
• Microsoft.Crm.dll
• Microsoft.Crm.Sdk.dll
• Microsoft.Crm.Platform.Sdk.dll

We can find these dll’s inside

../Microsoft Dynamics CRM/Server/Bin folder.

The above solution worked perfectly for Beta Versions of CRM 2011.

Recently we upgraded to RTM, and we had to deploy a WCF Service and custom web site inside isv.

For WCF service we had to make following changes to the web.config apart from the changes mentioned above

<serviceHostingEnvironment aspNetCompatibilityEnabled=”false”>
</serviceHostingEnvironment>
</system.serviceModel>

And in case of custom web site we had to add the following additional dll’s

• Microsoft.Crm.Sdk.Proxy.dll
• Microsoft.Xrm.Sdk.dll

Hope it helps!
