Edit: Sorry, I noticed too late that also the issues should be created in the new repo. I will create a new one here.


I am just setting up a project with ASP.NET as server and Blazor as client. I also use a Directory.Build.props file to redirect bin and obj folders into artifacts folder. This redirection causes the following error:

Cannot write embedded resource from assembly 'Blazor.Extensions.SignalR.JS' to
C:\Users\wilvin\Desktop\IBOW\artifacts\obj\xx\Debug\netstandard2.0\blazor_content\Blazor.Extensions.SignalR.JS because it is outside the expected directory

The difference is: IBOW\build\..\artifacts vs IBOW\artifacts, which is the same path. If I normalize the path with msbuild first, there is no problem. Example:



I think the best way to solve it in general is if this code block is normalizing the paths before comparison, so that no msbuild normalization is required.
