#### Issue description:

This is a repair item from a [CRI](https://portal.microsofticm.com/imp/v3/incidents/details/254267550/home) investigation. Developing Function App in portal and adding the template C# HTTP Trigger function throws Compilation warning message regarding the assembly reference after adding any new assembly reference as shown below.

Even without adding any new assembly and trying to make any change with the provided template by our portal also emits same warning message with the included assembly as well when trying to compile after any change.

Customer has refused to accept our recommendation of using VS for development and insists on using portal.
