Hello  Andreas Hansson,

After doing some research on your issue, I am sorry that I could not  
reproduce it and no similar issue found in community. So I suppose this
should be an environment or setting issue.

From your description, I got that after resetting VS.net to General
Development Settings, the build error disappeared.  It looks like this
error is caused by VS.net setting. In order to prove the guess, would you
please to reset the development settings again, and set it back to VB
development settings. The steps are:
1.    Open IDE, open menu item [Tools] / [Importing and Exporting Settings]
2.    Choose "Reset all settings", click Next
3.    Choose to back up your settings and click Next
4.    Choose "Visual Basic Development  Settings" and click Finish
Then please build the project again in debug mode. And check if there is an
error.

If there is no error, that means your original setting is not correct. When
you encounter such issue again, you can reset the development setting to
"Visual Basic Development Settings" instead of "General Development
Settings". It will also reset all the settings to default value.

If the error occurs again, based on the current information, I cannot
locate the real cause. In order to narrow down the problem, would you
please try this:
1.    If you have multiple projects in one solution, please try the following:
"    Use project reference instead of file reference if possible.
"    Delete the broken reference which is reported in the build error and add
it again.
"    Build each project separately from the bottom of the project dependency
tree to the top. And locate which project build is failed while all its
dependent projects are successfully built.
"    Please refer to
http://msdn.microsoft.com/en-us/library/ayds71se(VS.80).aspx for broken
rule troubleshooting.
2.    If the you have only one project, try to create a new project with the
same files and try to build it again. If this way works, that means it is a
project setting issue.

Anyway,  output content is important for us to do troubleshooting. I would
appreciate it if you could collect the information in the output window to
us. You can collect it by:
1.    Open menu item [Tool] / [Options].
2.    In the options window, check "show all settings" at left bottom.
3.    Select [Projects and Solutions] / [Builds and Run] in the left menu.
4.    Select "MSBuild project build output verbosity" to "Diagnostic", and
click ok button.
5.    Open menu item [Debug] / [Windows] / [Output], and you will see the
output window lay on the IDE.
6.    Rebuild the solution again and in the output window you will see the
trace information. If not, please select "Show output from" to "Build".
7.    Click on the content of the output window, and make your cursor focus in
the output window.
8.    Hold [CTRL] and press [A] on keyboard, and make sure all the content in
the output window is selected.
9.    Right click on the selection in output window, and choose copy. Or you
can Hold [CTRL] and press [C].
10.    Open an txt file and paste output into it. Send the txt file to me.

I am looking forward to your update and reply, and please let me know if
there is any additional information that I missed here.
