Description Anubhav Ranjan 2015-03-26 15:03:01 UTC
One of our customers is facing an issue when building the project.

Description: 
=========
After making modifications to a project in accordance with

http://developer.xamarin.com/guides/android/deployment,_testing,_and_metrics/publishing_an_application/part_1_-_preparing_an_application_for_release/
(or at least the problem coincide with that modifications), it stops building my Android application throwing an error message:

"Error 12 Could not copy the file "...\bin\Debug\x.dll.mdb" because it was not found."

"X" is the project file.

Comment 2 dean.ellis 2015-03-27 09:16:25 UTC
The problem in this case is that the various .dll's and .mdb files are listed as Content in the csproj. 

<Content Include="bin\Debug\someassembly.dll" />
    <Content Include="bin\Debug\someassembly.dll.mdb">
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>

It looks like someone accidentally added the contents of the bin/* directory to the project. These items  should be removed from the csproj.
