Add Quick Documentation sources from a different project

Can you compile SDK and reference it? By default documentation is compiled into xml file near each assembly.

Unfortunately I can't. The build requires access to private repos (I'm guessing) which I won't have access to for some time (waiting for access currently which may take some weeks).

I might be able to ask someone to do that for me though. Is there any documentation that you know of that explains where this XML file ends up? Is there one XML file per csprj? I might be able to get that from someone and add it to the project that I have.

When you compile with the DocumentationFile option, the compiler will search for all XML tags in the source code and create an XML documentation file.

Thanks, I found this https://stackoverflow.com/questions/47115877/how-to-generate-xml-documentation-for-csproj-with-multiple-targets and tried adding

<GenerateDocumentationFile>true</GenerateDocumentationFile>

to the Directory.Build.props file in the root directory. This seems to work to get the XML files generated but now I just need to figure out where to put them in my other project so that Rider picks them up and enables Quick Documentation for the classes that are coming from that library.

In Solution Explorer you may see references, find your reference, check its properties via context menu. There would be full path. Place xml files in the same folder as assemblies.

Thanks! Will try that.

Doesn't look like it's working.

I now have (I am of course omitting a bunch of stuff... but you get the point):

project/
+- dotnet
    +- project.sln
    +- prj1
    |   +- prj1.csproj [this project has a reference to my-ext-lib directory below]
    |   +- [prj1 source code and stuff]
    +- [a bunch of other projects, some with, and some without a reference to my-ext-lib]
    +- my-ext-lib
        +- My.Lib.Foo.dll
        +- My.Lib.Foo.pdb
        +- My.Lib.Foo.xml [I manually copied this file here]
        +- [a bunch of other My.Lib.*.* triplets here]

I've closed the project and started again but Rider does not seem to pick up the documentation from the XML files.

Anything else I could possibly try?

oh... hang on... I invalidated the caches in Rider, restarted and reopened the solution and now it seems to work. Thank you!
