Odd problem I keep having, wondering if its because I use types with same name as namespace?

UPDATE:

I ended up solving this in a way I did not expect - it apparently was not the namespace/typename collision I thought it was (to my surprise when I re-did it and it failed the exact same way). I think maybe this is minor VS bug - here's what happened:

--> The error path

• I added a Winforms project
• I added a reference to Lib1
• Lib1 appeared as an added reference
• (I revise my estimate of exactly when VS gets "confused") The next time I compile, things get broken and it's as if I never added the reference to Lib1.

--> Surprising way I ended up resolving the issue:

• I was taking random shots because I was confused and I decided to add the library a (slightly) different way.
• Instead of right clicking the References node in the Solution Explorer and choosing Lib1 from the "solutions" tab, I chose it from the "Recent" tab.
• When I added it, to my surprise, VS complained that it could not add the library
• The reason was my Library was set to .NET 4 and my Winforms app defaulted to Client profile.

--> the issue was resolved when I switched my winforms app to .NET 4

Background/Motivation:

I'm a lone developer - which is why when I have strangnesses like this one, I sometimes spend 20 minutes and if I can't figure it out I completely work around it. Sometimes these problems recur, and I spend another 20 minutes, and become annoyed with the workaround a second time, which finally makes me really want to figure it out. This is the case now.

Description of the Problem:

I'm coding along, in this case, I was prototyping an ASP.NET website with VS10.

• new project, ASP.NET website: Web1 (creates solution)
• add Project, C# library, Lib1 (adds to solution)
• Lib1: add Model.cs, View.cs, Presenter.cs, ...etc
• Web1: add a DataList to Default.aspx, bind data via Lib1
• Test it it works

---> Now I want to see my Lib1 work for a winforms project, basically proving to myself I can write Library code that doesn't care about the UI

• add Project, WinformsApp1 (adds to solution)
• add a DataGridView to Form1, bind data via Lib1

Then the wierdest thing happend (at least to me): At first, adding a reference to Lib1 and implementing the IView interface on Form1 works fine, but as soon as VS auto populates th开发者_如何学Pythone stubs for IView, everything goes to a state as if I didn't add the reference to Lib1. That is, the compiler tells me it doesn't know the definition of IView, and politely reminds me that I might have forgotten to add a reference, but the kicker is that it's talking about the code that it just generated and would not have been able to without that reference.

NOTE: If nobody knows just what this is and I'm wrong that this is a symptom of lone developer syndrome, I'll work up the example again and post the code (I just zapped it).

It sounds like you have a method in your interface that has the same name as the namespace, so when you populated the interface the compiler could no longer differentiate between the namespace and the method.
