Disabling OBSOLETE error in C#

Question

I am using the Microsoft TFS API and one of the properties on one of the interfaces has been marked as Obsolete and it instructs me to use a different property. Unfortunate

Answer 1

Visual Studio 2015

Build failing due to [Obsolete]?

This would only occur if "Treat Warnings As Errors" is enabled, and there is a method with the [Obsolete] attribute.

Method 1: Downgrade error to warning

Add 612,618 in the .csproj file (repeat for all sections):

    true
    4
    612,618
    true
    full
    false
    bin\Debug\
    DEBUG;TRACE
    prompt

If dealing with many .csproj files, see Appendix A: Notepad++ for search and replace.

Method 2: Ignore error in file

Note: This method is not recommended, because it hides the warnings for methods marked [Obsolete]. We still want to see a list of all calls to obsolete methods so we can upgrade them.

Use #pragma warning disable 612,618

Method 3: Ignore error in project

Note: This method is not recommended, because it hides the warnings for methods marked [Obsolete]. We still want to see a list of all calls to obsolete methods so we can upgrade them.

Edit the project (repeat for all sections):

Method 4: Ignore error in project

Note: This method is not recommended, because it hides the warnings for methods marked [Obsolete]. We still want to see a list of all calls to obsolete methods so we can upgrade them.

Manually edit your .csproj to disable warnings for specific errors. Add the tag 612,618 (repeat for all sections):

    612,618
    true
    bin\x64\Debug\
    DEBUG;TRACE
    true
    full
    x64
    prompt

Have a lot of files? No problem!

Open all .csproj files in NotePad++, then:

• Find: true
• Replace: true\n\t612,618
