This PR addresses missing documentation content in 8 Visual Basic error message files that were either completely missing their "To correct this error" sections or were missing the Error ID identifier.

Problem

The following Visual Basic error documentation files had incomplete error correction guidance:

• bc36613.md, bc36614.md, bc31537.md, bc31199.md, bc42207.md, bc31536.md - Had empty "To correct this error" sections
• bc30981.md, bc31538.md - Were missing both the "Error ID: BCxxxxx" line and had empty correction sections

Solution

Added comprehensive, actionable correction guidance for all 8 error files:

bc36613.md - Anonymous type member name inference from XML identifiers:

• Guide users to use valid Visual Basic identifiers explicitly
• Show how to access XML element values properly
• Explain Visual Basic naming rules

bc31538.md - Member override access modifier conflicts:

• Added missing Error ID line
• Explain how to use correct access modifiers (Protected vs Protected Friend)
• Guide users on reviewing base member access levels

bc36614.md - Range variable name inference from XML identifiers in LINQ:

• Show how to use valid range variable names explicitly
• Demonstrate proper XML element access in LINQ queries

bc31536.md - Friend access denied errors:

• Provide steps for adding public key information
• Show command-line compiler switches
• Explain InternalsVisibleTo attribute usage

And similar comprehensive guidance for the remaining files covering assembly references, friend declarations, .NET Framework updates, and inheritance hierarchy issues.

Validation

• All changes follow established documentation patterns from working error files
• Markdown linting passes with 0 errors
• All referenced links verified to exist
• Changes are minimal (108 lines added, 0 deleted)
• All 8 files now have complete Error ID and correction sections

Fixes #14193.
