Question

I have solution with 3 projects. Project one - Library . Project two - Service (asmx) . Project three - Test . In my service I have two config transform: PRODUCTION and TEST . They are equals, but name of databases is different. My solution:

I had similar issue and I did the following simply:

Go to Debug => Options => General => Remove the check mark for " Enable Just My Code "

This worked for me.

Answer 3

Another reason this can happen is that if you are sharing multiple projects between solutions and you have set up custom build configurations then simply changing from release to debug on the toolbar (or other shortcuts) can mess up the active build configuration and create all sorts of random consequences.

Make sure that Solution > Properties > Active Config is what you expect ('Mixed' is usually bad) and use Solution > Configuration Manager if in doubt.

I forgot again and the tactics popular on the intertubes did not, of course, work so this is partly a note to self...

Answer 4

As a future reference, the same issue can happen when you have the same assembly both in GAC and bin\\Debug folder. Just deleting the assembly from the GAC and it works again.

Answer 5

Require source files to exactly match the original version

This has to be unchecked.

Answer 6

Try adding or updating your .csproj file with the tag <DebugType>full</DebugType> inside <PropertyGroup> . This solved my problem.

Answer 7

I am using a solution with several projects (Visual Studio 2015). In my case, the problem was solved when I realized that one of the projects was being defined with another URL in: Project properties - Web - Servers - Project Url. After changing to use the same URL as the other projects, the problem was solved.

If you're doing multiple startup projects, make sure you have all your services your want to debug set to Start

Answer 10

In my case the project under which the debug breakpoints were not getting hit was also referenced by another solution which was at the time running. When I stopped that solution the breakpoints started hitting.

Answer 11

First try rebuilding your project by right mouse click the project > Rebuild If that doesn't work, try a clean of the project (right mouse click on the project > clean)

I had similar issue and I did the following: Debug=>Options=>General => Remove the check mark for "Enable Just My Code" This worked for my vs

Answer 12

如果库恰好是 C++ 并且有 C# 消费者项目实际调用它，则需要在消费者项目中转到 Properties -> Enable Native Debugging，并确保选中此框。

Answer 13

This can happen if you haven't set the current project as the startup project. In the solution explorer navigate to your project right click and select set as startup project.
