Method 'Started' in type 'Migrator.MSBuild.Logger.TaskLogger' does not have an implementation.

What steps will reproduce the problem?

1. svn checkout (bins on the download page are woefully out of date, and
don't match the documentation e.g. ScriptFile is not supported)
2. run build.bat (succeeds apart from some local properties missing warning)
3. Copy contents of build to my Source/ThirdParty dir
4. try to use the bins in a msbuild script:

  <PropertyGroup>
    <MigratorTasksPath>E:\Dev\XYZ\Main\Source\ThirdParty</MigratorTasksPath>
  </PropertyGroup>

  <Import Project="..\Source\ThirdParty\Migrator.Targets" />

  <Target Name="MigrationScript">
    <Migrate Provider="SqlServer"
        Connectionstring="Data Source=localhost; Database=XYZ; Integrated
Security=SSPI;"

Migrations="..\Source\XYZ.DatabaseMigrations\bin\Debug\XYZ.DatabaseMigrations.dl
l"
        Directory="."
        ScriptFile="MigrationScript.sql"/>
  </Target>

I just made one minor change - changed the To field to a Long as it should have 
been. 
But the Logger didn't change.

Either way, I wasn't able to reproduce this.

One thing - remove the Directory part. That is if you want to have the Migrate 
task 
compile your Migrations in memory. (Which I don't think currently is working 
with the 
MSBuild task).

I got this error too.  It was because I built the project with the .NET 3.5 
msbuild.
 To fix it, change line 108 of default.build so that the build will compile
Migrator.MSBuild.dll with .net 3.5 as well as .net 2.0:

line 108 used to be:
<csc target="library" output="${dir.bin}/Migrator.MSBuild.dll" 
define="${defines}"
debug="${debug}" if="${framework::get-target-framework() == 'net-2.0'">

should be:
<csc target="library" output="${dir.bin}/Migrator.MSBuild.dll" 
define="${defines}"
debug="${debug}" if="${framework::get-target-framework() == 'net-2.0' or
framework::get-target-framework() == 'net-3.5'}">

After changing that, the Migrator.MSBuild.dll was produced from running 
build.bat,
and the MSBuild migration task worked.

I noticed that there is a property called DOTNET2 which checks for either 
version of
the framework, but it doesn't seem to be used.

SVN 130
Thanks for finding that Lance, it should be fixed now.

The DOTNET2 was a define (to using in #if conditions in the code)
I made a property called mono and a property called dotnet that could be 
checked in various places to see if they 
were defined, so I think that should fix the. Please confirm.
