Error HRESULT E FAIL has been returned from a call to a COM component VS2012 when debugging

Question

I have a problem debugging a project migrated from Visual Studio 2010 to 2012   Every time I go to debug it I get the error message       Error HRESULT E FAIL has been returned from a call to a COM component     Compiling and running the application in a local IIS server works fine - just cannot debug   The other change other than moving to VS2012 is I am now using Team Foundation Server for source control and issue tracking - but I cannot see how that would affect it   I can narrow it down to the following   The project file - it has been migrated from VS 2003 as a website project and has been chopped and changed up the different versions Crystal Report runtime library  some other library   Anyone with any ideas

In my case  it appears that this message can be issued by Intellisense in Visual Studio 2013   The screenshot below shows the error at the bottom of VisualStudio 2013 after the first load of a customer project    I started googling what causes this error  and decided to try deleteing the user vxproj files as mentioned above   I found however that the project built with no issues  then after exiting and re-loading the project  I no longer received the error    So I m assuming in my case  it was some corruption due to moving the project from the customers directory tree structure to my local development disk tree structure    The key here is that in my case  the problem was transient   I did NOTHING and the problem appeared to resolve itself     Not generally a desirable thing as I didn t fix anything so it might come back

I wrote a simple program to open different folder while clicking on some specific buttons  I made the file properties as  content  and  copy if newer  to make deployment  So if I installed the exe file in the other software it actually install all of its resources and run the program fine  So  this is all about my program  While developing this sometimes if I run the program to check  it showed the error       HRESULT E FAIL has been returned from a call to a COM component     and I could not open the designer view  But Somehow I got an easy solution for me  I am not sure whether it will work for other or not    Here is the solution   Copy the whole application folder to another location  click on the application file from there   it will not work since it is just a copy and you will not see the designer   From the solution explorer delete the form1 vb   or may be a different name if it was changed during developing  In the solution explorer right click add an existing item  browse the file Form1 vb from where the folder is copied   orginal location  run the program in the new location  It will work   The problem with this solution if you want to add something and after running the program you find the same error  you have to copy the whole application folder in another location again and follow the above steps

I have been getting this a lot lately  I ve been having to create a new file and move the code to the new file to get around it  I fixed it by deleting the solution s suo file  as far as I can tell  it just stores info like what files are open in the IDE and stuff  and deleting it does no real damage   My file was seemingly corrupt   The IDE wouldn t remember what files were open when restarting  It was 1 7MB in size  which seems large  even for my 40 project solution  which rarely has more than 50 files open at once   Edit  I just recently had to do this in VS2017 but for another reason  it was taking longer to build and took 5  minutes to stop a debug session  deleting that pesky suo file fixed it right up  now anytime VS acts weird deleting SUO is my first port of call
