Is it really worth purchasing R# for VS2010?

Question

I heard that R#5.0 (still in beta) will support VS 2010. My question is VS2010 == VS2008 + ReSharper ?

I know there are many improvements to VS2010, so I 'm not sure weather is it really worth purchasing the R#5.0 for VS2010?

Answer 1

Well, I haven't explored VS 2010 new refactoring features that much, but its my understanding that VS has some but definitely not all of resharpers features implemented (From MSDN):

Navigate To

You can use the Navigate To feature to search for a symbol or file in the source code.

Navigate To lets you find a specific location in the solution or explore elements in the solution. It helps you pick a good set of matching results from a query.

You can search for keywords that are contained in a symbol by using Camel casing and underscore characters to divide the symbol into keywords.

For more information, see How to: Search for Objects, Definitions, and References (Symbols).

Generate From Usage

The Generate From Usage feature lets you use classes and members before you define them. You can generate a stub for any undefined class, constructor, method, property, field, or enum that you want to use but have not yet defined. You can generate new types and members without leaving your current location in code, This minimizes interruption to your workflow.

Generate From Usage supports programming styles such as test-first development.

IntelliSense Suggestion Mode

IntelliSense now provides two alternatives for IntelliSense statement completion, completion mode and suggestion mode. Use suggestion mode for situations where classes and members are used before they are defined.

In suggestion mode, when you type in the editor and then commit the entry, the text you typed is inserted into the code. When you commit an entry in completion mode, the editor shows the entry that is highlighted on the members list.

When an IntelliSense window is open, you can press CTRL+ALT+SPACEBAR to toggle between completion mode and suggestion mode.

So I guess it would depend on which of Resharpers features you want to use. If you are satisfied with the above which is certainly great improvements, then you don't need Resharper.

On the performance question, well it might perform better because of tighter integration.

Personally the above leaves me still needing a lot of features like (just the ones i can think of right now - might be more):

• There are as far as I can tell only about 6 refactorings, where resharper currently has more than 30
• No import type completion, which i use ALL the time. One shortcut adds to references and adds import statement
• No smart completion
• Change namespace to follow navigation structure and update all references with one shortcut
• Goto is more advanced in R# you can go to inheritors and bases, file member, recent files and edits and theres the fast goto feature
• Resharpers static analysis is far more comprehensive than what you get from VS

So what do you need? (I am definitely not giving up Resharper)
