1) When trying to copy the given source code you’ll mention that all the classes are unknown to Visual Studio, because all a lot of references are missing. So far I have no clue about the R#-class-architecture. So I started .NET Reflector, open ALL the .dlls in the R#/bin-folder into Reflector and use the search to find the .dlls to reference in my project.

2) When you have your first R#-plugin ready you want to test it. To do so you have to copy the dll containing your plugin in the R#-plugin folder. You may want to do this in a post-build event like this:


copy $(TargetPath) "C:\Program Files (x86)\JetBrains\ReSharper\v5.1\Bin\PlugIns\WobTest"


When you build your project with this post-build event it fails. This doesn’t work for two reasons. First: Win 7 denies access to that folder. Second: after another start of Visual Studio R# has loaded the plugin so you can’t copy a newer version over it.

My solution to this is a .cmd that starts Visual Studio without R# (devenv /safemode). I run this .cmd as administrator.

Now at least I can debug my plugins by starting another instance of Visual Studio (not in safemode!)

This solution is not cool, because developing R#-plugin without using R# in the development-process sucks…. any ideas?

a better solution…

Some minutes after I published this post, Benjamin pointed me to this page. Forget about my lines to 2). You don’t need a silly .cmd run as administrator not a post-build event. All you need to do is to start your debugging Visual Studio the the command line option /ReSharper.Plugin followed by the path to your plugin-dll.

/ReSharper.Plugin "R:\sandbox\ReSharperPlugInTest\PublicGoesVirtual\PublicGoesVirtual\bin\Debug\PublicGoesVirtual.dll"
