class libraries debugging

Question

I am creating a c# project using class libraries. The basic skeeton of the main project and the class lib. project worked well. When I tried to modify the class lib using some breakpoints for debugging, , the main project continues to use the old dll file only as against the newly modified one. I am building both the dll and the main project everytime I modify any one of them. Also the debugger dosn't stop at breakpoints. I am using c# with vs 2010.

Pls give me a solution soon as I am approaching  my completion date.

Answer 1

Are all projects in same solution? If not try to add in all one solution.

If its already in same solution, then add reference to project not the DLL.

Follow below steps to add Project reference.

For example, Project A is main project and Project B is DLL.

1. Right click on Project A, select "Add Reference"

2. Click on "solution" from lest side.

3. Checked the "Project B".

4. Hit "ok"

Hi RDchandrasekaran,

>>I am creating a c# project using class libraries. The basic skeeton of the main project and the class lib. project worked well.

So you mean that you add the class library project as a reference in your C# project, am I right?

>>When I tried to modify the class lib using some breakpoints for debugging, , the main project continues to use the old dll file only as against the newly modified one.

Do you mean that you modify your code in break mode while debugging If so, how about stopping debugging? Modify the code, and then debugging it again.

Whether it is related to the Edit and Continue?

If you stop debugging, please also clean and rebuild your whole solution, one possible reason is that the dll file was not updated, if you add a dll/project reference, you could see that it has the property called "copy to local", so please change the settings "copy local=true", re-debug it again.

Best Regards,

Jack
