将库dll添加到引用后，类库Intellisense未显示

Question

In C#, I made a ClassLibrary that has one Namespace and one Class. I saved it and build it. in other Projects, when i use it, I add it to my references by browsing to the .dll location.

But The Problem is that its name is not showing up in the Intellisense. ie when I: using ... my dll doesn't show .. I'm Importing the library to a ConsoleApp. both of the App and the library target Framework is .NET Framework 4.0 and I made their Assembly Version 4.0.0.0 so they're the exact same.

is there a setting or something that I'm missing ? how can i make it pop up ?

I'm using VS2010 Professional

Thank you for your help

也许这很有用，我有一个类似的问题，我有一个Web项目，通过选择项目添加对类库的引用，但如果我对类库进行了更改，我看不到该更改Web项目的intellisense，在尝试了很多东西后，我看到在最近添加的引用中，选项“Local Copy”的值设置为“True”，然后我将其更改为false并且everething正常工作！

I had a similar issue but in my case it was a property on the class. If you go to the file properties and look for a Build Action . Somehow mine was set to Content it had to be set to Compile .

I am using Visual Studio 2013. I hope this helps someone else.

Is the namespace for your assembly different than the namespace for your currently open project? I've had times when the current project and an assembly share the same namespace path the intellisense can mess up.

In general, Visual Studio is pretty good about intellisense generation, especially for C#. But sometimes there are some interesting conditions regarding ambiguities, and especially mixing project types where it just doesn't quite work.

Placing your content in the same namespace makes me wonder if you've actually fixed the problem (it may just be autocompleting the namespace in the currently loaded project rather than the assembly), but if it allows you to continue working, then go with it!

Right click on project on which you add reference of your dll/project select menu project dependancies and select/MarkCheckBox for reference project/dll. then it will work fine.

Answer 5

If the class library project had its name changed after creation, then intellisense may fail finding it due to directory issues, I believe.

I created my class with the generic "ClassLibrary1" or whatever, and then later changed the default namespace, class name, and project name inside of VS2017. I closed VS2017 and changed the directory name to match my default namespace, and then re-associated the project file in VS2017, and then re-added the reference in my main project file.

All seems to be fixed now.
