Introduction

I was working on a MVC Application (Razor Engine) using with Entity Framework. I triggered an error not able to populate entities while binding the controls with the database. I have written below detail of error as follows:

Error Description

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. 

Compiler Error Message: CS1963: An expression tree may not contain a dynamic operation

Solution (Error CS1963)

I went deeply under this issue and found here is the issue of @model case while calling the meta class to populate the control.

Incorrect Way to Call Up Class Entities

@Model slnMyapp.Models.clsSignup

I was getting error while call @Model, below I corrected in the way to lower case model @model

Correct Way to Call Up Class Entities

@model slnMyapp.Models.clsSignup

cs1963 error
Corrected Model Name
Corrected cs1963 error
Corrected cs1963 Error

Conclusion

This way was due to upper case of @Model, it is correct in a way @model, it is working fine for me. Compiler Error Message: CS1963: An expression tree may not contain a dynamic operation, this is the way how corrected this issue.
