Multiple references, not updating most recent version

Mooro81

I have built a C# program which consists of one executable project and 7 DLL's which are referenced. I'm having trouble with one DLL which is a user control which is used in the main project. Sometimes when I open the main project I get multiple errors saying, "Could not find type 'UserControls.ucDataInput'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built." Where ucDataInput is the user control. All instances of this control then dissappear. Sometimes I can fix this by re-compiling all the DLL's and then refreshing all references in main project. I also always have warnings when I comile saying, "Warning: The dependency 'DataStorage, Version=1.0.1857.23604, Culture=neutral' in project 'VesselComponent' cannot be copied to the run directory because it would overwrite the reference 'DataStorage, Version=1.0.1875.21789, Culture=neutral'." where DataStorage is another DLL i have created. I fear the problem may be cause because the DLL's reference each other and are also referenced in the main project. There are no circular references tho. So for instance if I have 2 DLL's A and B, A references B and the main project, C, references both A and B. I think what is happening is that unless A and C are recompiled everytime B changes then they are referencing different versions which creates a problem. Is this the problem? and how can I solve it without re-structuring my whole program? Cheers

Solved! I had the # character in the project path which causes this problem. What an annoying bug!

Actually on closer inspection it hasn't solved all my problems. It removed the warnings I spoke about earlier but there are still some problems. I have a DLL which is a user control I created for data entry in a seperate project but in the same solution now. It is used hundreds of times. When I open a form which uses one these controls in designer view I get the following error for each instantiation of the control, "D:\Development\C# Vessel\Vessel\VesselComponent\ucOpeningsReinforcement.cs(1911): The variable 'ucGasketWidth' is either undeclared or was never assigned." and " Could not find type 'UserControls.ucDataInput'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built." and the controls do not appear in the designer view. The solution compiles with no errors or warning and the program runs fine but it is annoying because I cannot select any of the control to edit their properties etc. All project references now reference the project file not the DLL file now. I thought the problems were connected but maybe not. Does anyone have some suggestion of what the problem may be. Thanks.

Stupidly I hadn't loaded all the projects into the same solution but I have now and fixed the problems as suggested. Thanks mate.

Did you write the assemblies in C#? If so, add their respective projects as a reference to your application instead of the binaries themselves. They will then be recompiled every time your application is compiled.
