TypeScript Compiler was given an empty configurations string

Question

I am getting a Warning in the Error List of Visual Studio when building my TypeScript project.

The TypeScript Compiler was given an empty configurations string, which is unusual and suspicious.

Answer 1

This is caused when this line ...

<Import Project="$(VSToolsPath)\TypeScript\Microsoft.TypeScript.targets" />

... precedes these PropertyGroup sections in the .csproj file.

<PropertyGroup Condition="'$(Configuration)' == 'Debug'">
  <TypeScriptTarget>ES5</TypeScriptTarget>
  <TypeScriptRemoveComments>false</TypeScriptRemoveComments>
  <TypeScriptSourceMap>true</TypeScriptSourceMap>
  <TypeScriptModuleKind>AMD</TypeScriptModuleKind>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)' == 'Release'">
  <TypeScriptTarget>ES5</TypeScriptTarget>
  <TypeScriptRemoveComments>true</TypeScriptRemoveComments>
  <TypeScriptSourceMap>false</TypeScriptSourceMap>
  <TypeScriptModuleKind>AMD</TypeScriptModuleKind>
</PropertyGroup>
