Does anyone know of a way to view all compiler warnings for a VB.NET project?

Question

VB.NET has this rather annoying limitation which caps compiler warnings reported at 100.

vbc : warning BC42206: Maximum number of warnings has been exceeded.         


        

Answer 1

You should read Configuring Warnings in Visual Basic and How to: Enable or Disable Compiler Warnings

For example, you can to the compiler options (under the project build properties) the following line

warnaserror:42206

this should (I haven't tried it myself...) disable your 100 errors limit.

On another note, 100 warnings is a very large number. You should probably go over your code, check and fix the reasons to those warnings.

Answer 2

The official answer is apparently "No." From Microsoft: "While this issue does exist, the Visual Basic Compiler Team has decided to leave the hard limit to the reported errors because it helps with performance."

Answer 3

As of VB11, in VS2012, vbc no longer has a maximum error limit when called from the command line.

There's probably a better link for this now, but this will do until I find one.

UPDATE: new link

Answer 4

I've had the same problem with SQL projects I've been working on; the limit is 200 warnings. Then as I fix them, new ones merge in so the number never goes down!

I found that if you look in the "Build" output in the "Output" tab you can see everything. In my case I have thousands. Just select all and copy/paste it into a text editor.
