| 1 | +# MSBuild Condition Fix - Version 2 |
| 2 | + |
| 3 | +**Date:** October 16, 2025 |
| 4 | +**Status:** ✅ Fixed |
| 5 | +**Files Modified:** 125 `.csproj` files |
| 6 | + |
| 7 | +--- |
| 8 | + |
| 9 | +## Problem Discovered |
| 10 | + |
| 11 | +### Initial Bug (Original Code) |
| 12 | +The original project files had: |
| 13 | +```xml |
| 14 | +<When Condition="'$(SolutionName.Endswith(`Nuget`))'"> |
| 15 | +``` |
| 16 | + |
| 17 | +**Issue:** Typo - `Endswith` should be `EndsWith` (capital S) |
| 18 | + |
| 19 | +### First Fix Attempt (Incorrect) |
| 20 | +I replaced with: |
| 21 | +```xml |
| 22 | +<When Condition="'$(SolutionName.Contains('Nuget'))'"> |
| 23 | +``` |
| 24 | + |
| 25 | +**Issue:** MSBuild doesn't support `.Contains()` directly in this syntax. |
| 26 | +**Error:** `MSB4092: An unexpected token 'Nuget' was found at character position 27` |
| 27 | + |
| 28 | +### Second Fix Attempt (Also Incorrect) |
| 29 | +I then tried: |
| 30 | +```xml |
| 31 | +<When Condition="'$([System.String]::Copy('$(SolutionName)').IndexOf('Nuget') >= 0)'"> |
| 32 | +``` |
| 33 | + |
| 34 | +**Issue:** Parenthesis placement was wrong. The comparison should be outside the property function. |
| 35 | + |
| 36 | +--- |
| 37 | + |
| 38 | +## Correct Solution |
| 39 | + |
| 40 | +### Final Fix (Correct ✅) |
| 41 | +```xml |
| 42 | +<When Condition="$([System.String]::Copy('$(SolutionName)').IndexOf('Nuget')) >= 0"> |
| 43 | +``` |
| 44 | + |
| 45 | +### How It Works |
| 46 | + |
| 47 | +1. **`$([System.String]::Copy('$(SolutionName)'))`** |
| 48 | + - Creates a System.String object from the SolutionName property |
| 49 | + - This is the MSBuild property function syntax |
| 50 | + |
| 51 | +2. **`.IndexOf('Nuget')`** |
| 52 | + - Calls the IndexOf method to find "Nuget" in the string |
| 53 | + - Returns the index position (0 or greater if found) |
| 54 | + - Returns -1 if not found |
| 55 | + |
| 56 | +3. **`>= 0`** |
| 57 | + - Compares the result of IndexOf |
| 58 | + - `>` is XML-encoded `>` |
| 59 | + - If result is >= 0, "Nuget" was found in the solution name |
| 60 | + |
| 61 | +### Why This Works |
| 62 | + |
| 63 | +- MSBuild property functions allow calling .NET methods |
| 64 | +- The syntax is: `$([FullTypeName]::StaticMethod(args))` or `$([FullTypeName]::new(args).InstanceMethod())` |
| 65 | +- IndexOf is a well-supported string method |
| 66 | +- The comparison happens outside the property function evaluation |
| 67 | + |
| 68 | +--- |
| 69 | + |
| 70 | +## Examples |
| 71 | + |
| 72 | +### Solutions That Match |
| 73 | + |
| 74 | +These solution names will trigger the NuGet package references: |
| 75 | + |
| 76 | +``` |
| 77 | +"Krypton Explorer 2022 - Nuget.sln" → Contains "Nuget" → TRUE |
| 78 | +"Krypton Docking Examples 2022 (Release) - Nuget.sln" → TRUE |
| 79 | +"Navigator Examples - Nuget.sln" → TRUE |
| 80 | +``` |
| 81 | + |
| 82 | +**IndexOf("Nuget") >= 0** evaluates to `TRUE` |
| 83 | + |
| 84 | +### Solutions That Don't Match |
| 85 | + |
| 86 | +These solution names will use Dev project references: |
| 87 | + |
| 88 | +``` |
| 89 | +"Krypton Explorer 2022 - Dev.sln" → No "Nuget" → FALSE |
| 90 | +"Docking Examples - Dev.sln" → FALSE |
| 91 | +"Navigator Examples 2022.sln" → FALSE |
| 92 | +``` |
| 93 | + |
| 94 | +**IndexOf("Nuget")** returns -1, so **-1 >= 0** evaluates to `FALSE` |
| 95 | + |
| 96 | +--- |
| 97 | + |
| 98 | +## Complete Conditional Logic |
| 99 | + |
| 100 | +```xml |
| 101 | +<Choose> |
| 102 | + <!-- When solution name contains "Nuget" --> |
| 103 | + <When Condition="$([System.String]::Copy('$(SolutionName)').IndexOf('Nuget')) >= 0"> |
| 104 | + <ItemGroup> |
| 105 | + <!-- Use NuGet packages --> |
| 106 | + <PackageReference Include="Krypton.Toolkit.Canary" Version="100.25.8.234-beta" /> |
| 107 | + <PackageReference Include="Krypton.Navigator.Canary" Version="100.25.8.234-beta" /> |
| 108 | + <PackageReference Include="Krypton.Workspace.Canary" Version="100.25.8.234-beta" /> |
| 109 | + </ItemGroup> |
| 110 | + </When> |
| 111 | + <Otherwise> |
| 112 | + <ItemGroup> |
| 113 | + <!-- Use project references (Dev solutions) --> |
| 114 | + <ProjectReference Include="..\..\..\..\Standard-Toolkit\Source\..." /> |
| 115 | + </ItemGroup> |
| 116 | + </Otherwise> |
| 117 | +</Choose> |
| 118 | +``` |

| 122 | +## MSBuild Property Function Reference |
| 123 | + |
| 124 | +### Syntax |
| 125 | +```xml |
| 126 | +$([FullTypeName]::StaticMethod(parameters)) |
| 127 | +$([FullTypeName]::new(constructor-params).InstanceMethod(params)) |
| 128 | +``` |
| 129 | + |
| 130 | +### Common String Functions |
| 131 | + |
| 132 | +| Function | Example | Notes | |
| 133 | +|----------|---------|-------| |
| 134 | +| IndexOf | `$([System.String]::Copy('text').IndexOf('sub'))` | Returns position or -1 | |
| 135 | +| StartsWith | `$([System.String]::Copy('text').StartsWith('tex'))` | Returns true/false | |
| 136 | +| EndsWith | `$([System.String]::Copy('text').EndsWith('xt'))` | Returns true/false | |
| 137 | +| ToLower | `$([System.String]::Copy('TEXT').ToLower())` | Returns lowercase | |
| 138 | +| ToUpper | `$([System.String]::Copy('text').ToUpper())` | Returns uppercase | |
| 139 | + |
| 140 | +### XML Encoding in Conditions |
| 141 | + |
| 142 | +Since we're inside XML, special characters must be encoded: |
| 143 | + |
| 144 | +| Character | Encoded | Usage | |
| 145 | +|-----------|---------|-------| |
| 146 | +| `<` | `<` | Less than | |
| 147 | +| `>` | `>` | Greater than | |
| 148 | +| `&` | `&` | And | |
| 149 | +| `'` | `'` | Apostrophe (rarely needed) | |
| 150 | +| `"` | `"` | Quote (rarely needed) | |
| 151 | + |
| 152 | +--- |
| 153 | + |
| 154 | +## Testing the Fix |
| 155 | + |
| 156 | +### Local Test |
| 157 | +```bash |
| 158 | +# Build a NuGet solution |
| 159 | +msbuild "Source/Krypton Explorer/Krypton Explorer 2022 - Nuget.sln" /restore /p:Configuration=Debug |
| 160 | + |
| 161 | +# Should restore NuGet packages and build successfully |
| 162 | +``` |
| 163 | + |
| 164 | +### Expected Behavior |
| 165 | +1. MSBuild evaluates `$(SolutionName)` → `"Krypton Explorer 2022 - Nuget"` |
| 166 | +2. Calls `[System.String]::Copy().IndexOf('Nuget')` → Returns position 30 |
| 167 | +3. Compares: `30 >= 0` → `TRUE` |
| 168 | +4. Uses NuGet package references |
| 169 | +5. Restores packages from NuGet.org |
| 170 | +6. Build succeeds ✅ |
| 171 | + |

| 173 | + |
| 174 | +## Lessons Learned |
| 175 | + |
| 176 | +1. **MSBuild != C#** |
| 177 | + - Can't use C# syntax directly |
| 178 | + - Must use property function syntax |
| 179 | + |
| 180 | +2. **Property Functions Are Powerful** |
| 181 | + - Access to .NET Framework methods |
| 182 | + - Proper syntax is critical |
| 183 | + |
| 184 | +3. **XML Encoding Matters** |
| 185 | + - `>` must be `>` in XML |
| 186 | + - `<` must be `<` in XML |
| 187 | + |
| 188 | +4. **Test Locally First** |
| 189 | + - MSBuild errors can be cryptic |
| 190 | + - Local testing helps catch issues early |
| 191 | + |
| 192 | +5. **Parenthesis Placement** |
| 193 | + - Property function result must be evaluated first |
| 194 | + - Then comparison happens outside |
| 195 | + |
