Hello devs,

we've decided to upgrade Razor from version 2.0 to 3.0 in our MVC 4 project. The reason is that Razorengine (which uses Razor 3.0) is used be the other project which needs to be connected to the MVC one. As app domain can't normally contain 2 different versions of assembly, it was decided to upgrade to Razor 3.

So could you please tell - are there any breaking changes in Razor 3.0 compared to 2.0 version, and can ASP.NET MVC 4 work normally with Razor 3.0?

MVC3 is compatible only with Razor v1
MVC4 is compatible only with Razor v2
MVC5 is compatible only with Razor v3

They cannot be mixed, unfortunately.

From Razor 2 to Razor 3 there were no deliberate breaking changes, but I think there were maybe a couple of bug fixes that caused a slight change in behavior in obscure cases (such as redundant usage of "@" in C# code). But in general Razor has been highly compatible across versions.
