Recently, I encounter the bug of code CS1513 while trying to compile old project of MVC3 into newer version.

Compiler Error Message: CS1513: } expected

I found out that without proper usage of Razor syntaxes, you will encounter this when you upgraded MVC to latest version.

There are several ways might cause you this error. For example,

Instead of

@if(@variable)

You should

@if(variable)

Instead of

 @{int a = @Model.Property }

You should

@{int a = Model.Property }

Conclusion, you should be aware of the Razor V3 Advanced Parser feature which is different with the old version.
