MsbuildSonar Runner +Fxcop - No fxcop issues are posted to server.SonarDashBoard shows 0 technical debt

问题

I am using Sonarqube 5.1 with MsBuildSonarRunner for my c#.net project analysis. Sonarqube 5.1 has come with C# 4.1 plugin, Recently I upgraded to 4.2. I have created a quality profile with ONLY Fxcop rules. I have followed the steps mentioned in Sonar site for analysis.

In analysis, I see that FXcop rule violations are captured. But when I browse to SonarDash board, It shows technical debt as 0 and issues as 0. I have reviewed my steps many times and I don't see any mistakes from my side. What could be the reason why Issues are not posted to server.

Here is my Build command log. I see clearly FXCOP rules are applied and violations are printed on console during build phase.

FxCop analyzes assemblies, and relies on *.pdb files to map issues back to locations within the source code (i.e. to specific *.cs files at specific lines).

The issue reported by CA1823 seems to be on a field, which due to limitations of the *.pdb format are not being mapped back to source code. These issues are ignored during the import of FxCop results into SonarQube. You can verify that by manually opening the FxCop report (whose path you'll find in .sonarqube\out*\ProjectInfo.xml).

There is already a ticket to improve this in a future version of the C# plugin: https://jira.sonarsource.com/browse/SONARFXCOP-32

Update November 18th 2015

After many comments on this answer (see below), the root cause of the issue was finally found: The SQL Server collation must be case-sensitive (CS) and accent-sensitive (AS).

SonarQube 5.3 is expected to fail faster when this is not the case, to avoid these kind of strange problems: https://jira.sonarsource.com/browse/SONAR-6884
