问题
I have a ASP.Net Web API project that is failing to load in Visual Studio 2019. When I try to reload the project from the Solution Explorer I get the error:
The method or operation is not implemented
Any ideas what might be causing this?
回答1:
A bit of a cryptic error message - the actual problem preventing the project from loading was:
In the csproj file for the project, section, I had
<UseIIS>true</UseIIS>
and IISUrl pointing to a local site that was not yet set up on IIS, e.g.
<IISUrl>http://localhost:12321</IISUrl>
where there was no site bound to localhost:12321
