ASP.net web site unable to reference dll

Question

User-468333257 posted

I could add reference to one of my custom made dlls in ConsoleApp, and Web application(Add reference)

But when I added reference to WebSite, and tried to import namespace, it complains the following:

The type of namespace xxxx could not be found. (are you missing a directive or assembly reference)?

In a website, put the dll in the Bin folder.  Add a using statement in the code behind.

It didnt work
using xxx doesnt detect the namespace

This only has problems in website

Web application and console app are fine

Answer 3

Is the Bin folder right under the root of the site?   And I have no idea what "xxx" means.   I assure you that it works - I have several asp.net websites that are not applications.  You have not posted any code so there is not much more anyone can tell you.

The dll is a custom dll i built from a console app built into class lib, not any kind of open source dll you get from downloading online.

xxx is the namespace but somehow after i click project->add reference ->select these dll and add
It still cant detect


I didnt have this problems for web app and console app, only for web sites

You don't need to "add reference" for a website for code you are putting in the Bin yourself. Again, since I have no visibility to what you are doing, I can't tell what is wrong.

Yes, the dlls are already in the bin folder, yet still same issue<br>

Is there some kind of vs logs in vs2015 that i can refer to , to see what is wrong with vs not detecting my dll?

Whats the use of providing code when it cant detect my dll

using namespace; already gives error

Hi z080236,

How about installing it into the global assembly cache?

(Note:Each computer where the common language runtime is installed has this machine-wide code cache. The global assembly cache stores assemblies specifically designated to be shared by several applications on the computer.)

Add the file to GCA

gacutil.exe /i MyFile.dll

Then you can get the version and

gacutil /l MyFile

For more details, please refer to the following articles:
