Fix: Visual Studio Achievements and FxCop problem

Posted on 25. Januar 2012 by Marcus Haßmann

Actually there is a problem with FxCop and Visual Studio Achievements (with Visual Studio Professional): the FxCop assemblies can’t be loaded.

Here is a workaround (note: you have to install FxCop 10.0 – not FxCop 1.36):

x86: You have to copy all files from "C:\Program Files\Microsoft Fxcop 10.0" to "C:\Program Files\Microsoft Visual Studio 10.0\Team Tools\Static Analysis Tools\FxCop".

x64: You have to copy all files from "C:\Program Files (x86)\Microsoft Fxcop 10.0" to "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Team Tools\Static Analysis Tools\FxCop".

LINQPad

Posted on 21. Januar 2012 by Marcus Haßmann

LINQPad is a modern SQL query tool. Say goodbye to the old SQL Management Studio. LINQPad supports SQL Express, SQL 2008, SQL 2005, SQL 2000, SQLite, MySQL and Oracle.

LINQPad standard edition is free and can run without installation. The executable is 3MB and is self-updating. There is even a version that runs in Google Chrome.

Autocompletion is an optional extra. You can buy LINQPad Pro for $39.00 or LINQPad Premium for $58.00 (introductory price). The Premium Edition also unlocks LINQPad’s ability to write cross-database queries. Just control+drag additional databases from the Schema Explorer onto your query.

Here is the official LINQPad website: http://www.linqpad.net

I had this problem today. You may have an underscore in your username? So you can edit your username per regedit.exe,

key HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\VSAchievements –> value “username”.

Prefer readonly to const
Prefer the is or as operator to casts
Use conditional attributes instead of #if
Always provide .ToString()

Remove an assembly from the global assembly cache (GAC)

Posted on 25. November 2011 by Marcus Haßmann

You can manage your global assemblies with the gacutil.exe which comes with Microsoft SDK. You can find this tool for instance in folder "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\".

This is an example about removing one assembly:

"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\gacutil.exe" /u Assembly.To.Uninstall

Add a trailing backslash to a path

Posted on 15. Oktober 2011 by Marcus Haßmann

In my old Delphi days I used IncludeTrailingPathDelimiter() to ad a backslash to a path variable.

In C# you can use this code to combine a path and a filename:

Code Snippet

Path.Combine(folderBrowserDialog1.SelectedPath, fileName);
