ReSharper: Namespace does not correspond to file location

Question

I renamed a folder and updated my namespace declarations, but ReSharper 6 claims that the namespace should be a reflection of how it was before the rename. Where is it storing the file location data?

I suggest that you delete all *.ReSharper files. Resharper will recreate them from scratch without the "garbage". – Taluk

I thought I had. I suppose I should give it another go. – Infuriate

It's all in *.ReSharper files. If all were deleted and you still get a namespace issue, I believe it is indeed related to your folder's structure... – Taluk

This also happened to me using Resharper 8.2.3. The problem is that it was ignoring folders with a space in the name. So MyProject>Service Contracts>Common was resolving to MyProject>Common instead of the expected MyProject>Service_Contracts>Common – Cloudland

Answer 1

Check to make sure your assembly name matches your new namespace. If you've changed your folder structure to match your new namespace, you may still see the ReSharper alert until you update the project properties.

Yeah... project file and not just resharper files. – Infuriate

@Will S That's exactly what was vexing me until I found your post. In VS go to Project > [project name] Properties > Application & change "Assembly name" (this may not be required in your situation) as well as "Default namespace". Once I did this, ReSharper 7.7.1 quit complaining about the namespace. – Broomrape

Answer 2

As delliottg's comment says, in Visual Studio, go to

Project > [project name] Properties > Application

and change "Assembly name" as well as "Default namespace".

I also had this problem with a folder/namespace and none of the above steps fixed it.

In my case I had to do this in Visual Studio:

• Right-click the "problem" folder in the solution explorer to open the properties
• Ensure the "Namespace Provider" is set to true

This fixed the ReSharper issue for me and I was able to adjust namespaces as normal.

I had a folder that was giving me total grief. Resharper kept telling me to add it to a folder with the same name within the folder. This was the perfect solution. – Patronymic

Ugh, yet another stupid hidden setting in visual studio! – Expellee

Answer 4

Root namespace is needed to be changed as following.

Thank you this worked. Also if you check the CSPROJ file there will be a <RootNamespace>OLD_NAMESPACE</RootNamespace> entry which you can remove to make sure the assembly name and root name are from the csproj file – Nne

I use Resharper 2019.3.2 in VS 2019 vs 16.5.2 and I had similar issues.

When developing, I first work out my namespace hierarchy in a single project, then split the project in seperate class libraries. In the first stage, it is convenient to always let the subdirectory correspond to the namespace.

For example, my prototype MeshTools.dll project currently contains:

 Meshtools ........................ 3 cs-files in \MeshTools
   MeshTools.HeightField .......... 2 cs-files in \MeshTools\HeightField
   MeshTools.VectorTools .......... 3 cs-files in \MeshTools\VectorTools

The above answers all assume one single namespace per project. Renaming directories manually may confuse Resharper and that can be repaired by setting the default assembly in the .csproj file to the proper namespace. Thanks for the tip.

However in my case, I have several namespaces in a single project, with each namespace in a Solution directory corresponding to a real directory. Setting the default assembly "Meshtools" does not affect ReSharper behaviour for HeightField and VectorTools, when things have gone wrong with the renaming.

I googled this issue and came by https://www.jetbrains.com/help/resharper/Refactorings__Adjust_Namespaces.html#

It turns out there is a right-click option on a Solution Directory -> Properties. You will find an option to decide, if the Solution Directory is a NameSpace provider or not. When something has gone wrong, Visual studio will reset the field to False. Set it back to True and Resharper will correctly refactor namespace or file location when needed..

If you're using JetBrains Rider, go to the Solution Explorer and right click on the csproj file, then properties in the context menu. In my case the Assembly Name was already updated but "Root Namespace" wasn't, updating Root Namespace allowed JetBrains to automatically update all namespaces.
